Presbyopia is the natural deterioration of eyesight that we all experience as we age. It starts from around the age of 45 and gets progressively worse until we lose all of our near vision accommodation.
Current solutions like progressive or bifocal lenses maintain a reasonable level of distance vision correction but, because of the way they are designed, give a very small viewing area and limited field of view for near and middle distances. This can make common near tasks like reading and computing difficult, especially over long periods.
Adlens adaptive lens technologies offer an alternative solution, putting you back in control and allowing you to see sharply at any distance, with a better field of view, just as you did when you were younger.
