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.
