The most popular eye surgery today is LASIK surgery. It is efficient, fast, very gentle and with few complications. For most people the LASIK surgery can help them no matter if they are nearsighted, farsighted and have 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.
