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!

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 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

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

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.
