LASIK is the most popular type of eye surgery today. It is at the same time fast, efficient and gentle. And the complications of are rare. For most people a LASIK surgery is a good solution to improve their sight in the cases of nearsightedness, farsightedness and/or astigmatism.
The strength of reading glasses was originally based on the patient’s age. For a man of 30″40 years lenses of 2 degrees were used, for 70″80 years, lenses of 4 degrees. It wasn’t until the middle of the 19th century that glasses started to be issued by people who knew some basics about optics.
Eyeglasses or specs are fundamentally a set of frames bearing a couple of lenses borne in front of the eyes, normally for vision rectification, eye protection, or alternatively for protection from ultraviolet rays.
