We get presbyopia as we age. Normally, most people become presbyopic at the age of 40. Even more sadly is that more and more young people get vision problems, mainly nearsightedness at a young age. But vision is never a problem when it comes to fashion. We've always got solutions for the problems. Specially made glasses, known as reading sunglasses are designed for people who are presbyopic to read as anyone else. Now there are many types of lenses available for making reading sunglasses. The main three include single vision, bifocal and progressive lenses.

Single vision reading sunglasses are the simplest form of reading sunglasses. They can only correct near vision and objects in the distance will appear blurry. In comparison, bifocal reading sunglasses can be both used for viewing objects in near and long distance. The drawback is there are clear lines that divide various segments for different functions. Finally, progressive reading sunglasses have not got those visible lines and are pretty much like normal vision. One thing that we should be concerned when choosing reading sunglasses is to make sure the lens is polarized. Since you always wear reading sunglasses outdoors, it is important to take measures to prevent any eye damage or injuries. Polarized lens can do this pretty well.
