Buying a pair of glasses without first finding out about the difference between lenses and glasses can be quite dangerous. For those of you who might buy glasses just for style or complementary accessories, it does not matter if you do not find out first. But if you buy glasses, intending to help your eyesight, then learn or understand them first, it becomes one thing that must be done. Specific glasses for eye sufferers, of course, are not made haphazardly, and these will be equipped with special lenses that are tailored to those of you who have problems with your eyes. The use of laser mirror mounts is one of the technologies that play an important role in the manufacture of lenses from glasses. Therefore, you need to understand the type of lens before you decide to buy it.
In this case, lenses have various types such as Bifocal lenses, progressive lenses, mirror lenses, plus lenses, and so on. In this article, we will explain two types of lenses, namely progressive lenses and mirror lenses. For glasses with progressive lenses, this is not much different from the use of Bifocal lenses because these do have the same focal point, namely dual, and are certainly useful for helping someone who has eye problems in the nearsighted and farsighted categories. The advantage that can be obtained from the use of glasses with progressive lenses is that the user will have to see from a moderate angle of view. However, the progressive lens here does not have a dividing line, or unlike that of the Bifocal lens.
Next for glasses with mirror lens types. It is not used on clear glasses but rather is used on sunglasses. This type of glasses is quite different from the previous types of glasses with lenses. Glasses with this type of lens are quite a lot of fans.
