Our eyes represent an optical system through which we view the world around us. As the most sophisticated camera, they consist of several lenses, or even two: the cornea (the clear covering of the front of the eye) and the lens inside our eyes. There are different vision defects and there will be relevant applicable methods of their correction.

Glasses: they are composed of two main elements – lenses and frames that holding them in front of our eyes. The lenses must match the features of our face and certain geometrical parameters, such as center distance, vertex distance, angle, etc.

Advantages of vision correction using glasses:

  • Creating an image of smart person;
  • Wide availability of different frames in all possible price categories;
  • Wide availability of lenses, each designed to correct a specific defect;
  • The possibility of combining the optical and sun lenses;
  • Ease of use and maintenance.

Disadvantages of vision correction with glasses:

  • Incorrect spatial perception and narrowing of the field of view;
  • Evidence of “physical disability” to others;
  • Unacceptable change in appearance;
  • Risk of injury to the face and eyes in some situations;
  • Restrictions on the choice of leisure activities and sports.

Contact lenses are worn directly on the cornea of the eye and form with it a single optical system similar to tightly coupled lenses in the lens of the camera.

Advantages of vision correction using contact lenses:

  • No destruction of spatial perception and normal viewing angle;
  • Invisible to others;
  • Ability to change the color of eyes;
  • No restrictions on the choice of activities and sports;

Disadvantages of vision correction using contact lenses:

  • Direct contact with the eyes and the related risk;
  • A need for adherence to strict hygiene and wear;
  • Frequent money expenditure on new lenses and care products;
  • Inconvenience in certain circumstances;
  • Limitation of usage with certain diseases (colds, allergies, etc.)

Surgical vision correction is done either by a special diamond scalpel, which makes incisions in the cornea of the eye or with a laser, which gives the cornea a new form. Both interventions provide for a change in the optical power of the cornea.

The advantages of surgical and laser vision correction:

  • Reducing dependence on optical means of vision correction;
  • Quick and painless procedure of correction;
  • A short recovery period.

Disadvantages of surgical and laser vision correction:

  • A risk of serious and irreversible complications to the eyes;
  • A likelihood of further deterioration of vision;
  • Set of contraindications.

As you can see, there is no ideal method of vision correction, therefore try to find a balance between life and work and pay attention to eye health.

Hassle Free Glasses Refunds And Replacements

glasses refunds and replacements

You do need to keep in mind that there is a line between defective frames and lenses and those that have obviously been abused or have gone through an accident. Generally speaking, the seller and the manufacturer aren’t obliged to replace your glasses in those cases, though some stores may provide warranty or insurance plans for them.

If you got the right prescription, but still aren’t comfortable with the vision that your new eyeglasses provide, you can just get your eyes rechecked and have your prescription fixed as needed.

The majority of optical stores out there won’t mind remaking the lenses for you free free after the first adjustment that your doctor makes on your prescription. In the majority of cases, one change is all that is needed to give you comfortable vision all throughout anyway.

Choose Reputable Optical Stores!

Most of the time, you can expect a complete refund or a replacement from an optical store if you buy an item with a manufacturer’s defect, like a broken frame brought about by weak solder joints; or the wrong prescription, coming about from the way that the lenses were fabricated or the way that your eyes were measured. By law, you can also ask for a complete cash refund, if the item was already broken when you bought it.

Anyway, reputable optical stores generally won’t mind providing you with a replacement since the majority of eyewear manufacturers will stick to their products and give out free replacements to retailers in cases of manufacturing defects. Plus, both the manufacturers of eyeglass frames and lenses and the optical stores tend to place their reputation on a pedestal because they don’t want their customers to think they have inferior eyewear available.

Can You Simply Change Your Mind?

A grey area will come into play if you are hoping to return your glasses just because you aren’t fond of them after taking them home. If your prescription is right, then not being happy with your glasses could come about because of the heaviness of the eyewear that makes it slip down your nose all the time; the unflattering lenses and frames; or just a poor style choice, in general.

Depending on your overall objection, optical stores will have policies in place. These policies may differ from store to store, though, so your success in getting a refund or getting your eyeglasses exchanged will depend on the store that you bought them from to begin with.

Some eyewear manufacturers are just sweet! Warby Parker made it clear via their youtube channel that should you have any problems, doubts or change of mind you can easily return you pair of glasses hassle-free!

Uncovering the Latest Technologies in Eye Care Optics

Today we will be discussing progressive lenses – this particular term is applied to the most advanced type of lenses for the correction of vision with a smooth change of the focal distance between the “far” and “near” bands.

The farsightedness – the eye’s ability to focus on close object only is forcing us to use lenses. For majority, diopters are needed when looking at close objects, while using other lenses for distanced items. People can certainly use two different types of glasses with conventional lenses – one pair specifically for reading, while others, if they are needed – to look into the distance.

When we use reading glasses and suddenly need to look at more distanced objects, we have to look above the lens of our glasses. Thus, there are special frames for reading, so-called “half-moon glasses” designed for this purpose, which are narrow and cover only the lower part of the field of our vision. But still, it is much more convenient to be able to have glasses equally good for all distances.

So, in order to use the same lens to see both near and far objects, the lenses should combine different diopters. Such lenses are called multifocal optics – various diopters mean a different focal length, hence the name. Our usual lenses are, therefore, called monofocal, or “single vision lenses” – they have only one specific diopter.

The opportunity to combine a single lens for both functions comes from the fact that we look differently at close and far objects. When we read, our eyes look down, and the directions of the left and right eyes converge with each other very close, so pupils are shifted towards the nose. When we look into the distance, our eyes are pushed down slightly, and the pupils are in their normal position. When we first look at the book, and after – into the distance, the direction of our vision goes through different parts of the lens. Therefore it is possible to make the lens sections with different prescriptions.

First multifocal lenses have historically been bifocals. These lenses, as you might have guessed by their name, combine two specific fixed diopters. Basic diopter – for general view, and an additional diopter for close vision – a special segment, located in the lower portion of the lens, and shifted to the nose. The shape and size of the segments may vary. Most often, segments have a horseshoe shape with a flat or arcuate top and a width of 25 to 35 mm. There are also circular segments of the same size.

Bifocal lenses allow us to use the same points, whether we look into the distance, or at close objects. However, they have a set of drawbacks. In terms of comfort, they deliver quite an abrupt change in the optical power of the lens when you turn your sight from distant objects to close. In addition, it often turns out that you need some intermediate diopters between “close” and “distant” bands.

From an aesthetic point of view, the border’s segment is clearly visible from the outside. As reading glasses are associated with old people, bifocals frankly scream about your age. Furthermore, the segments are seen from outside, working as small magnifier, increasing your lower eyelids and the region under the eyes – not a favorable visual effect. Despite these numerous shortcomings, bifocal lenses are still being produced in large quantities.

There is another group of lenses called trifocal, where intermediate segment has smaller additional diopters than basic, providing a clear vision for medium-length distances. The rest of the trifocal lenses suffer from the same drawbacks as bifocals.

Most modern lenses that are replacing outdated bifocals and trifocals are progressive lenses. Their main difference is a smooth, or “progressive” increase of the optical power as we turn our sight from remote objects to those that are located in the middle distance, and then – to the closest. Progressive lenses have no segments with fixed different prescriptions and their optical features are based on complex geometry of their surfaces. The design of progressive lenses and their respective production are the most recent achievements of applied science and optical technology.

There is a huge variety of lenses available on the market – both of early designs and more modern (with a wide channel). In general, millions of customers today are more than satisfied with progressive lenses, especially when compared with bifocals. Progressives with a wide channel are more “tolerant” to small movements relative to the lenses of our eyes, and therefore provide for even greater level of comfort.

Progressive lenses have specific requirements for how and where you buy your glasses. Any lenses require a proper placement after the frame is assembled, but in the case of progressive lenses, this requirement becomes an absolute imperative, and technology to ensure this requirement is very specific. Therefore, the correct production of glasses with progressive lenses can be carried out only by professional optometrists who have undergone a special training, and constantly improve their skills in this area.

Choosing the Right Lens Material For Your Glasses

Plastic CR-39 Lenses

Plastic CR-39 is basically just regular plastic, which is what the majority of lenses out there consist of. Plastic CR-39 is usually used in clear lens glasses and can cover the mid-range of practically every prescription possible. Glass aside, it is also known to have the best clarity out of all of the other lens materials and is known to be the cheapest lens material out there. Aside from that, it is also very lightweight, easy to tint and less likely to break compared to glass.

The downside of Plastic CR-38 would be that it is a bit more fragile compared to trivex and polycarbonate. Also, the plastic will be thicker the higher your prescription is. However, if your prescription is still relatively low, or if you don’t need prescription lenses at all, then plastic CR-39 would be a great option for you. Plus, you will be able to save money with it at the same time. Naturally, this only counts if you don’t add any extra features, such as UV protection or scratch resistance, though.

Polycarbonate Lenses

Polycarbonate refers to a kind of plastic that is lighter, thinner and more durable compared to other lens materials. It also happens to so soft that it is considered to be one of the most shatter-resistant materials out there next to trivex. This is actually why polycarbonate is used for all sorts of eyeglasses and why it would be such a great match for most people out there. Polycarbonate would generally be highly recommended for anybody under 18 years old, as well as athletes, active kids and those who work in labor-intensive environments. Also, polycarbonate lenses usually already come with UV protection and scratch resistance included in their price tags.

The downside is that polycarbonate may scratch a bit easier compared to plastic CR-39. It is also a bit more expensive and isn’t as clear as plastic CR-39 or trivex overall. While the majority of people don’t really notice these disadvantages, those who are more sensitive to them may want to opt for plastic CR-39 or trivex instead. Polycarbonate cannot hold dark tint, either, and people with high astigmatism might experience additional distortion, as well.

Trivex Lenses

Trivex is relatively new and has all of the traits that polycarbonate has. However, it is much more stable, clearer and lighter in weight for rimless and semi-rimless glasses.

However, trivex does cost a bit more money and is a bit thicker compared to polycarbonate overall. It doesn’t have as many design options as polycarbonate, either.

Glass Lenses

Glass is the original material that was used for every lens back in the day and is the one with the best clarity and optical quality to this day. It is also more scratch-resistant and stable, and doesn’t flex or distort in any way. This is why people who work in mechanical fields or farms still prefer glass over any other lens material out there.

However, because of how heavy and expensive glass is, more and more frame lenses are now using plastic materials. This has made glass much less available in the market and has made it more expensive, as well. Its weight happens to put too much pressure onto the nose and even leaves skin marks sometimes. Plus, it requires special equipment for its production and it takes longer to produce, too.

High Index Lenses

High index refers to the type of plastic that is considered to be made of the topmost quality out of any of the other plastic materials used for lenses. Because of this, it provides the best clarity for prescription lenses. This material would be perfect for those who have high prescriptions because it stays thin, no matter how high the prescriptions may get.

However, high index is very expensive and tends to be oversold and overprescribed to people who don’t even need its quality for their glasses overall. Insurance companies usually won’t cover the upgrades of this material, either, so you may end up paying more than expected in the end.

Conclusion

Let me assure you that choosing the right lenses for your glasses is the most important step. You can still spend plenty of time deciding on specific shape, but i advise you to pay special attention to lens material and be aware of their pros and cons. You may be interested in checking how the lenses are being created and fitted. This process is not easy and requires highly-skilled professional work.

Why It’s Important to Choose Glasses Properly

Eyeglasses happen to be very important parts of certain people’s lives because they can help them see things more clearly in the world. This would be especially true if the people in question have to wear their glasses all day and everyday.

If this is the case with you and you are not simply following the trend of hipster glasses, then you have to make sure that you choose comfortable eyeglasses with a precise prescription to last you a long time. After all, ill-fitting, uncomfortable or inaccurate glasses could cause problems, such as blurred vision and headaches that can make things harder for you in the long run. This is why it would be so vital to purchase to quality glasses from a reliable and experienced lab from the beginning.

Problems Associated with Wearing Unsuitable Glasses

Some of the most obvious problems associated with wearing the wrong prescription would be fuzzed or blurred vision. While you might not notice a wrong prescription if there is only a minor difference involved, a bigger difference could cause dizziness, vertigo, nausea and headaches from eye strain.

Fortunately, using glasses with the wrong prescription won’t bring about any long-term side effects. In other words, your vision won’t get worse if you keep wearing them nor will your eyes get damaged in the process. However, if you don’t correct your vision properly, you could risk certain injuries at work or while driving.

There are several kinds of eyeglasses, like bifocal lenses, that will require a certain adjustment period before you can get used to them. This may last a few days or even a few months. Some signs that you are having trouble adjusting to your lenses include disorientation and headaches.

How to Choose Glasses for Computer

31 Aug

different monitorsPeople are spending more and more time with their computers, tablets, smart phones and other technology. No wonder this is a very big burden for the human eyes. The question is – are there any special “magic” computer glasses that ensure our eyes are not getting tires while using our gadgets?

Problem may be related not to the computers and gadgets (though some time ago, there were myths about harmful monitor radiation), but the general problem for our eyes working “at close range.”

The myths about the harmful monitors have disappeared. Experts agree to the fact that the only way to facilitate the health of our eyes when working with different monitors is to use the yellow coat on the surface. Such coating cuts the blue-violet component of the color spectrum of monitors, which is the most annoying for our eyes (although there is no scientific evidence on this point and the conclusion comes from general considerations).

What happens with our eyes when working at close range? Let’s review three different case scenarios:

  1. Normal vision (or vision already corrected with contact lenses): experts recommend using lenses up to +2 diopters;
  2. Nearsightedness: it is strongly recommended to use glasses for distanced objects;
  3. Farsightedness: people are advised to wear glasses with progressive lenses.

In any case, don’t forget about simple yet effective recommendations when working at your computer:

  • It is important to organize the optimal lighting of the workplace;
  • Make sure you do regular breaks and relaxation exercises for your eyes;
  • Carry out regular checks to maintain vision health.

The 21st century is full of different gadgets, each of those are putting an excessive pressure on our sight. So, the combination of healthy nutrition, exercises and maintenance will pay off well at later stage!

Choosing The Right Food For Your Eyes

11 Aug

carrotsWithout exception, all probably heard that carrots are one of the top products that improve vision, and its use in the diet plays a huge role in maintaining good eye health, so the benefit of this vegetable, as well as the benefit of carrot juice cannot be underestimated. But what other useful products can be used to improve our eyesight? What can we eat to maintain our eye health and reduce the risk of various diseases?

Answers to these questions are simple yet many people don’t pay enough attention to procedures that must be followed in order to look after such a complicated part of our body. As for improving vision, and for maintaining the general health of the whole organism, it is necessary to use nutritious and vitamin-rich foods. Here is the list of the top selected products that will help you get rid of your glasses if not for the rest of your life, but at least for some time if you so wish.

Kale

The substance called carotenoids was found in green leafy vegetables such as spinach chard, kale and others and proved to be important for your eyesight. These products – ordinary antioxidants – act as natural sunglasses to protect the eyes from ultraviolet radiation, as well as protecting cells from the harmful damage.

Wild Berries

You will be pleased to hear that various berries are here to correct your vision. Scientists have shown that the antioxidants contained in the berries reduce the risk of cataracts and other sight issues. Summer is the perfect time to stock up on vitamins – starting with fresh strawberries, followed by blueberries and raspberries. It is so easy to make desserts or add the fruits to salads!

Milk

Milk is also considered as one of the top health-improving products. Cheese, eggs and milk are a good source of vitamin A that is considered to be the best for our vision.

Fish

Omega-3 fats, which are found in oily fish, play a key role in the health of the retina. Eating at least once a week a fatty fish such as salmon, trout, mackerel, sardines, herring and others will reduce the risk of sight problems and the development of cataracts.

Nuts

Another group of products ideal for sight are nuts. They contain vitamin E, which is very important for normal eye condition. Almonds more likely to contain this vitamin, so eat them alone, or cook your meals using almond oil – your eyes will always be healthy.

So, we have introduced you the healthiest food products that will help you maintain your perfect vision. But there are some other things you can do for the same purpose in conjunction with the diet: make sure you do some eye exercise from time to time, especially when your work involves long hours in front of computer!

Buying Special Frames For Your Nerd Glasses

9 Sep

We have already covered plastic and metal materials available on the market. How about very special frame?

If you are looking for a unique style and don’t mind shelling out extra money for it, then you should definitely try out the eyeglass frames and design accents that consist of the materials in this article. If you don’t know where to look for this unique and expensive eyewear, then high-end optical boutiques would probably be your best bet for now.

Wood, Buffalo Horn and Bone Frames

Wood, buffalo horn and bone frames are usually unique handmade pieces. While bone and wood are less adjustable, more expensive and stiffer compared to the other frame materials just mentioned, people tend to like them because of their one-of-a-kind beauty.

On the other hand, buffalo horn frames look very elegant and will warm to the temperature of the body. They really are very different compared to any other frames that you might have tried before.

Leather Frames

While leather isn’t as practical or as durable of a material compared to the other accenting materials used for frames, it does provide a very fashionable and interesting look overall. Leather is mostly used across the frame fronts and on the temples and, recently, velvet has been added to wrap up limited edition sunglass models, as well.

Semi-Precious or Precious Stones

Semi-precious stones, precious stones and even crystals have been used as frame accents in the past most notably on the temples. Some of the most popular choices for this include Swarovski crystals, onyx stones and turquoise gems. However, a lot of people also use diamonds for a more luxurious touch. These designs are most commonly worn at dressy formal occasions.

For something a bit less expensive, rhinestones can easily do the trick, too. However, they usually create a more retro and flashy look, most of all when used in upturned cat eye frames.

Choosing Right Frame Material Is Not Only About Fashion

When choosing eyeglass frames, there are certain things that you will need to consider in order to make the best choice for you and your lenses, such as the material’s cost, durability and flexibility. However, you will also need to consider your current allergies. If you have any allergies to certain materials at the moment, then you will have to limit your options to frame materials that are known to be completely hypoallergenic.

Overall, your choices in terms of eyeglass frames are completely limitless. There are full-rim, semi-rimless and rimless varieties, for instance. Since frames tend to reflect a person’s personal style, though, it is nice to know that you now have the chance to choose and take your pick between specs that are retro, modern or traditional based on your personal tastes and preferences.

Choosing Metal Frame For Your Pair of Nerd Glasses

8 Sep

Recently we have been discussing variety of plastic frames. Now let’s check what is metal frames are able to offer!

Metal Frames: Classy And Trendy

To help make your decision in terms of eyeglass frame materials easier, here is everything that you need to know about the metal kinds in layman’s terms.

Titanium

Metal Frame Glasses

Titanium refers to a silver-gray metal that is corrosion-resistant and has been used for various things in the world so far, such as medical implants and space capsules.

Titanium frames are very light and strong, and are nickel-free and hypo-non-allergenic at the same time. This material is normally used to produce frames that have the perfect balance of comfort and strength. Titanium eyewear also tends to exist in various colors for a modern, clean and colorful look. They are hypoallergenic, too.

There are also titanium alloy frames out there, though, which are very light and durable, and have great memory shape retention. These frames usually work well in extreme circumstances and succeed therein, too.

Aside from that, there are other titanium frames out there that are made out of an alloy combination of nickel and titanium or copper and titanium, as well. Generally speaking, titanium alloy frames tend to be much cheaper compared to 100% titanium frames, too.

Flexon

Flexon refers to a titanium-based alloy that is both popular and unique. Flexon frames are sometimes called memory metal frames, as well, because of their ability to go back into shape even after being twisted, crushed or bent. These frames are corrosion-resistant, lightweight and hypoallergenic, too.

Stainless Steel

Stainless steel is generally durable, lightweight, springy, non-corrodeable and strong and is usually used as an alternative option to titanium in order to produce thin and fine frames that are still very durable and strong overall. This material also has a low toxicity and is hypoallergenic and nickel-free.

Aside from that, stainless steel is easy to find and is very affordable, too. While it is mostly an alloy of chromium and steel, it may contain other elements, too. The majority of stainless steels consist of 10 to 30% chromium, though, providing it with great resistance to heat, corrosion and abrasion.

Stainless steel would be the perfect material for people who sweat a lot, play energetic sports, live in warm countries or live near sea water. This material comes in different degrees of purity, too.

Nickel Alloy

Nickel alloy is the material that is used to make the majority of the frames in today’s market and consists of a mixture of various metals of various proportions, depending on which part of the frame needs to be flexible or stiff. In its greatest form, though, this material is malleable, durable and strong. And, even though it has some nickel in it, which may bring about skin irritation, top quality versions of these frames can give a great barrier between the base metal and the wearer in the end.

Overall, nickel alloy isn’t completely resistant to corrosion, though. As mentioned earlier, some people might experience skin reactions because of it. However, the good news is that, aside from buying top quality versions, this can also be prevented by using nickel-free plating, like palladium. There are some nickel frames hat use thick rolled gold kinds of covering, too. These gold-filled frames are no longer used as often now as they were used back in the day, though, due to their high cost and thickness.

Beryllium

Beryllium refers to a steel-gray metal that is much cheaper compared to titanium eyewear. It is corrosion-resistant and tarnish-resistant, as well, making it the perfect choice for people with highly acidic skin and those who spend a lot of time around saltwater.

This material is also very strong, flexible, lightweight and easy to adjust. Plus, it comes in a wide array of different colors, as well.

Aluminium Alloy

Aluminum frames are very corrosion-resistant and lightweight and are mainly used by high-end eyeglass designers due to their overall unique look.

Aside from being the most abundant material in the world right now, it is also the most widely used and nonferrous one. Since pure aluminum tends to be weak and soft, though, commercial aluminum mixed with some iron and silicon is mostly used for more strength and durability.

Nerd Glasses: Plastic Frame Materials To Choose From

Ray Ban Plastic Frames

You have probably noticed the huge amount of trendy glasses in the crowd. This can be attributed to the very recent trend of so-called hipster or nerd glasses. Today we are going to discover the world of numerous materials to design and produce spectacle frames. Generally speaking, there are three major groups of frames materials when it comes to eyewear production: plastic frames, metal frames and special frames. We will try to go through every group one by one discovering advantages, possible issues and latest fashion trends. But for the time being, let me concentrate on plastic materials.

Plastic Frames: Be Creative By Choosing Any Color You Want

Thanks to the many different eyeglass frame materials available in the market nowadays, you currently have a lot of options to revamp your look. So, when shopping for new sunglasses or eyeglasses, you might want to ask your optician what your options are in terms of colors, lightness, durability, brands, uniqueness, price and hypoallergenic materials before making your final decision.

Overall, though, finding eyeglasses with all of the traits that you find most important could simply lie in finding the perfect material for you – one that has the unique strengths that you need for your glasses. Generally speaking, spectacle frame materials have two main categories: plastics and metals. Here, we will focus on plastic frames.

SPX

SPX refers to the lightest plastic material that can be used to make spectacle frames out there. Despite its light weight, though, it is known to be very strong overall. Plus, it is hypo-non-allergenic and very resistant to perspiration absorption at the same time. As such, it can also retain its luster and color quite well. The best part is that SPX comes in various finishes, too.

SPX can be quite hard to adjust as time goes by, though, since it tends to get very brittle in colder weather and tends to shrink with age, as well. Sometimes, this could make removing the lenses very hard without actually breaking the frames. This is why SPX frames shouldn’t be reglazed at all. If it absolutely has to be done, though, then you must do so at your own risk.

Optyl

Optyl is very light yet very durable, too. It is also known to be a top quality plastic and is available in both translucent and solid colors to suit your preferences. Aside from that, it can also resist perspiration and retain its shape quite well.

Optyl is basically a cast-molded thermosetting plastic, which means that it can stay in a certain shape until it experiences very high temperatures. In extreme heat, it may soften and be re-shaped into new adjustment shapes as needed, as well. The reshaping will need to be done during its cool-down, though. So, while optyl can be tricky to adjust overall, it can be very useful as a material since it can retain any adjusted shape forever.

Nylon

Nylon eyeglasses were first introduced in the 1940s. However, because of certain problems related to them, such as their brittleness, a lot of eyeglass manufacturers started using blended nylon to make eyeglasses instead. Nowadays, these blended nylon frames are considered to be both lightweight yet strong.

Nylon also works well for performance and sports frames, which usually consist of trogamid, gliamides or grilamid materials that are resistant to different temperatures, and are stiff yet flexible at the same time. Nylon is also easy to mold into wraparound styles and other shapes that are popular nowadays.

Carbon Fibre

Carbon fibre frames are generally made of plastic that is reinforced with carbon fibres and metal on the sides to make it stronger despite its light weight.

You have to be careful of carbon fibre frame coatings, though, because they tend to come off when their wearers perspire a lot. While expensive versions don’t really suffer from this problem, it may be best to steer clear of carbon fibre altogether if you know that you sweat a lot.

Glass Fibre

Glass fibre can be quite hard to adjust if it isn’t perfectly made as needed.

Cellulose Acetate

If you want to have all of the colors of the rainbow available to you, then cellulose acetate would be the perfect material for this. Cellulose acetate isn’t just very cost-effective overall, either; it is also a creative and lightweight option for eyewear, in general. Laminated cellulose acetate frames with layered colors are quite popular nowadays, for one, and look best when the light colors are inside. All-black frames are good options, too, though.

There are several drawbacks that come with plastic frames, though. For starters, they are much easier to break compared to metal frames, and they can burn if ignited, too. Aside from that, sunlight exposure and time can make them weaker, as well. Their colors may also fade as time goes by, though not as much as the way colors fade in more modern materials.
