Many drivers would wear sunglasses when they are driving so as to block strong sunlight, so would they do when driving in snowy day so as to keep off glare. Sunglasses, at those times, serve as a great help for them to keep eye health and to eliminate unnecessary car accidents. However, when the cars are driven from bright places to dark places, like tunnels, sunglasses would be burden some which would bring drivers side effect to see vision forward clearly. If drivers constantly putting on and taking off sunglasses, it would be fairly inconvenient for them and be rather dangerous. Then how to liberate drivers from this trouble? Wearing transition glasses would be helpful.

Transition glasses are special eyewears which appear to be regular eyeglasses in normal circumstances, but would turn to shades when encountering strong light, like sunlight, glare and any reflection. It is amazing, right? Then you must ask how do transition glasses work? How would they exchange color accordingly?

The myth of transition glasses lies in the lenses, which are made from photochromics glass. During the production of photochromics glass, elements sensitive to light, like argentic chloride and silver halide, etc., are mixed in. A small amount of copperoxide catalyst are added as well. When silver halide, meeting with light, would have chemical decomposition, during which process, many black silver micelles would be produced and distributed evenly on the glass. As a result, the glass turn to black. When brought to dark places, with the promotion of copperoxide catalyst, silver and halogen would get chemical combined once more, as a result of which the glass return back to be transparent again. This is how the magic come from. The decomposition and chemical combination can carry through for limitless times.

The photochromics glass, besides applied in eyeglass production, are used in many other fields, for example the production of windows. Houses or cars equipped with photochromics glass need no curtains to block sunlight, for in sunny days, the windows would automatically turn black and when envenfall comes or when in cloudy days, the windows get back to transparency.

Therefore, with transition eyeglasses, life are full of miracles and fantasy. Additionally, transition glasses are able to absorb UV, which is fairly good for eyes. They can be among eye wears of top grade.

Forms of varifocal glasses

Eyeglasses widely employed by massive people are mainly single focal, mainly because these wearers only suffer from myopia, hyperopia and other ordinary vision errors. However, some unfortunate people may get more than one eye problems at the same time. In particular, when people are over forty, they are vulnerable to presbyopia and other eye problems, with both distant and nearby vision symptoms. For this, many multi-focal glasses can be employed, like bifocal glasses, trifocal glasses, and progressive glasses and so on. However, some of these multi-foal glasses are not ideal as people can ever think, like bifocals and trifocals, due to their vision lines. Therefore, no-line eyeglasses are usually deemed as better options, for they have more than two focal, but varifocals, and are usually called varifocal glasses.

Strictly speaking, bifocals and trifocals can not be called varifocal eye glasses, in which no-line bifocals and no line trifocals are included. Therefore, from a broader perspective, varifocal eye wear can be fallen into the following groups, namely, no line bifocals, no line trifocals, progressive glasses. Here is some detailed information about these eye wear.

No line bifocal glasses are upgraded from ordinary bifocals, mainly because many wearers are tormented by the vision lines in the lenses. Bifocals are combined by two different lenses, each of them are responsible for nearby vision and distant vision respectively. However, the transition between the two lenses is too radical and wearers will always suffer a lot when they change their visions. Or in some cases, wearers have to suffer from headache and dizziness. Therefore, the transition between the two vision areas should be natural and smooth, so as to ensure wearers have more vision comfort. And the emergence of no line bifocals has really benefited these sufferers. No such radical vision transition can be found between the two, for the transition areas are designed in varifocal.

No line trifocals are other important varifocal glasses in the industry. They are also upgraded from ordinary trifocal glasses. Similar to no line bifocals, these no line eye wear can ensure wearers have natural vision transition. And the only difference is- they have more lenses than no line bifocal glasses.

Progressive eyeglasses are some of the most popular viarifocal eye wear. They are composed of various focal, at least 20 focal and can make all vision transition in a progressive way- this is why they are called progressive. These eye wear are so perfect in vision transition that many wearers always think no eyeglasses are on their faces.

In addition, almost all these varifoal eyeglasses are used be designed in larger sizes. But now, they can also be designed in ordinary sizes, due to the employment of special materials.

In a word, varifocal glasses are the best options for people with both nearby and far vision problems. And all wearers are suggested to select according to their personal situations.

Sun glasses in the market are aimed at wearers of different groups, and their quality varies a lot as a result. However, some people have their eyes injured by wearing low end or low quality sun wear, like some replica sunglasses made by unknown manufacturers. And the best solution is to buy top sunglasses, which do not refer to a specific brand name, but a series of sunglass wear with top quality and high fashion. And the real top sun wear are much better than people can ever imagine.

Firstly, top sun wear can be prescribed according to users’ personal situations- this mainly refers to prescription sun wear. For people who have vision errors, sunglasses should be more carefully made, mainly because their two eyes usually have different prescriptions. However, many ordinary sunglasses are designed with the same power or prescription in both two eyes- neither can they cure wearers’ vision errors, but will also cause great damages to the eyes. Contrarily, all these problems can never be found on top sunglass, which are completely prescribed according to wearers’ personal eye conditions. In other words, top sun wear can not only cure wearers’ vision problems, but also offer great vision comfort and freshness.

Secondly, top sun glasses can be completely designed in light of wearers’ personal tastes and interests- all of them can be called designer sunglasses. Wearers’ personal tastes are now some of the most important factors to be considered by both buyers and sellers. But ordinary sunglasses in the market are designed and manufactured with the same models- might be produced from assemble line; and no difference can be told among all of them, let alone wearers’ personal tastes. Accordingly, top sunglasses are particularly designed for wearers with different personal tastes. For example, if buyers are bored with those traditional colors, like black, while, red, they may ask for mixed colors or other options; if they do not like a specific shape, they can also ask for the ones they love most. In a word, top sun glasses are meticulously manufactured for people who are in need of top designer sunglasses.

Third, top sun wear can offer 100% vision protection, no matter what the environment is like. Compare with those common sunglasses that are not always guaranteed in quality and vision safety, top sun glasses can really bring wearers more vision safety and comfort. These sun wear can block all harmful rays, like UV rays, Glares, blue light and so on.

Forth, top sun wear are the best articles for fashion and elegance. Fashion can always be firstly found on top sun glasses that are usually designed and manufactured by the world’s top fashion design houses. Just because of this, top sun glasses are also considered as symbol of social stratus.

Ultimately, but not lastly, there are still many other unique features on top sunglasses, each of which can expound wearers’ personal tastes and elegance and all sun glass wearers can have a try.

Eyeglass is a necessity for people who have vision problems. Choosing a pair of eyeglass is not easy if you have no knowledge about eyeglass.  Here is some information about eyeglass which can help you a lot.

While choosing eyeglass frames, the face shape, color of skin, eye and hair all should be taken into consideration. Photochromic lenses can change its color in different light conditions. These lenses become darker once exposed to UV light. Nowadays, most eyewear lines provide one or two frames in relatively larger sizes. Some typical brands are Chesterfield XL frames for men from Safilo, Prada frames from Luxottica and Silhouette frames.

People with presbyopia are supposed to buy reading glasses from eye doctors, rather than simply pick up one pair from drugstores. On one hand, those one-size-fit-all reading glasses are problematic for people with different prescriptions in two eyes, resulting in side effects such as headache. On the other hand, regular eye exams from eye doctors can detect underlying vision problems as early as possible.

There are some tips that can help wearers prolong their eyeglasses lives. Trendy frames in some cases should be avoided because they become out-of-date quickly. New lenses put in old frames can save much money, especially in children whose prescriptions change more frequently. Spring hinge styles can better protect eyeglasses from breaking. Scratch-resistant coating is available for lens protection.

There are many warning signs in children that may indicate the need for eyeglasses, including close TV watching or book reading, squinting, frequent eye rubbing, light sensitivity, excessive tearing and poor performance in school. Polycarbonate lenses are most usually recommended for children.

Regular computer users may feel uncomfortable with bifocal eyeglasses or reading glasses. In fact, computer screen reading requires intermediate vision, which can be provided by computer glasses, progressive lenses or trifocals. In some cases, occupational lenses are needed to provide task-specific vision.

Not all eyeglass lenses provide proper UV protection, such as some plastic lenses. Those lenses offer UV protection only if they are applied with UV coating. One superior lens material is polycarbonate, which has built-in UV protection.

Choose the right pair of eyeglass which suits you the most when you have vision problem. Just remember the comfort should always be put on the first place when choosing eyeglass.
