​Presbyopia

Presbyopia is a refractive disorder of the eye which occurs as you age. It affects your near vision, and not so much a disease as a natural age-related occurrence. The condition is often confused with far sightedness (hyperopia), but the two are different as presbyopia is caused due to aging when the natural lens of the eyes lose their flexibility over time, while farsightedness is caused due to the shape of the cornea’s curvature which causes incorrect focusing of light rays in the eyes.

As we age, the natural lenses in the eye gradually thicken and become less flexible. Changes in the proteins that make up the lens, as well as in the muscle fibres surrounding the lens makes them less elastic.

Presbyopia is a common eye disorder and occurs naturally, affecting almost everyone. It starts after the age of 40, and symptoms start with difficulty reading or looking at things close by.
