Question

what is presbyopia ?how can it be corrected?​

Answer 1

As people age, the lens becomes harder and less elastic, making it more difficult for the eye to focus on close objects. For centuries presbyopia was corrected with the use of bifocal eyeglasses. Today there are many ways to correct presbyopia with eyeglasses, contact lenses and surgery.

Symptoms: Blurred vision; Eye strain; Headache

Treatments: Glasses

Although it can't be reversed, it is easy to correct. The simplest way is to wear reading glasses. Laser treatment and other kinds of eye surgery have hardly any advantages, but are associated with a lot of risks.

Hope this helps!
