In order to block harsh sunlight in hot summer days, and to keep off the had glare from snow fields, people would usually choose to wear sunglasses. However, one demerit of sunglasses is that the wearers can not see things clearly indoors, especially those wearing prescription sunglasses, for they could neither take off the sunglasses nor put on them for a clear vision. Then how to get a resolution? With the development of science and technology in sunglass manufacture, people in modern times have put the axe in the helve. Transitions sunglasses, which have a magic power to change the color of the lens according to the change of sunlight intensity outside, are able to off a clear vision both indoor and outdoor.

The secret lies in the lenses, where argentic chloride and silver bromide, etc., are added. Those items are able to get chemical radiations: 2Ag=2Ag+X2. The argentic chloride can be resolved into silver and halogen, when encountering strong sunlight, or more specifically speaking ultraviolet radiation. The silver atoms are little black pellets, which when distributed uniformly, can darken the lenses. Similarly, when the light weakens, the chemical radiations reverses: 2Ag+X2=2Ag, and the lenses turn to transparent again.

Nevertheless, not everyone is advisable to wear transitions sunglasses. To wear them blindly would lead to sever harm to eyes. There are four groups of people inadvisable to wear transitions sunglasses, and they are:

People with excessive myopia. They originally view faintly, and if transition lenses are applied for them, they would feel rather hard to see characters, and even objects in vision clearly.

People with both myopia and astigmatism. They are probably to see things clearly in strong light, and then, the silver halide of transition lenses would always in a state of deterioration. As a result, it is impossible to have a clear vision easily for the wearers. Moreover, the pupils of the wearers would be in dilation state always, which is rather bad for eye health.

People with presbyopia. The reason why they are not transitions sunglass persons is the same with that of the people with excessive myopia.

People suffering from eye diseases, like cataract and glaucoma, etc.. Transitions sunglasses would lead to the worsening of their sickness, for they pose stress on their eyes.

Eyeglasses can now be sold separately in either frames or lenses and there are many replaceable lenses and frames as a result. However, it seems that lenses are much popular than frames, for many people love to fix the same frames with different lenses. Among so many replaceable lenses, transitions lenses, also called photochormic lenses or transition photochromic lenses, are very popular, mainly because buyers posses special passion for them.

Transition lenses in different colors are available in the market. There are usually grey, black, green, brown, yellow and other colored transition eyeglass lenses. This can really satisfy buyers with different color demands. However, some people may have such question that is there any difference among transition lenses in different color; are light tinted lenses worse than dark tinted lenses in terms of vision protection, and so on. Such worries are reasonable but not necessary. There are no difference among all lenses in terms of function and vision safety, no matter what the color are and how dark or light the color is. Therefore, people can choose transition lens of any colors according to their personal tastes.

Transitions lenses  in the market can be made from various sorts of materials and can meet buyers’ different needs. Glass, plastic, polycarbonate and other new materials in the industry are widely employed to manufacture these lenses. And the only difference among transition lenses from different materials is cost. Usually, these lenses made from ordinary materials are cheap while those from the latest materials are expensive. And buyers can buy the lenses that fit them most according to their personal income.

There are also many transition eyeglass lenses that can be used to rectify different vision errors. Usually, these lenses are compatible with many other lenses. For example, there are many special transition lenses for presbyopia, like transition bifocals, transition trifocals, and so on. Therefore, these lenses are suitable for all people whether or not they have vision errors.

By and large, transitions lens can be fallen into two major groups, say, common lens and sunglass lens. The former is ideal for daily uses, especially in other reasons, not summer; the later is very good option for people who are in need of sunglasses in summer. Therefore, if fixed onto different frames, they can be called transition glasses and transition sunglasses respectively.

Lastly, transitions lenses make it possible that wearers have more options for different vision needs. Any one who wants to have a try on these special lenses can visit firmoo.com for more detailed information.
