Nearsightedness or myopia

For a nearsighted person, close objects are clear, but distant objects—such as a school blackboard, a street sign, or a face across a room—are blurred and difficult to distinguish. Over 25% of adults worldwide are nearsighted.

Myopia, also called nearsightedness or shortsightedness, is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed.

For people with astigmatism, all objects both near and far are distorted. Images are blurred because some of the light rays are focused and others are not.

Presbyopia, what is Presbyopia?

Presbyopia is a natural occurrence associated with aging in which the normally soft and flexible crystalline lens of the eye hardens and becomes less elastic.

This makes the lens less able to focus incoming light from near objects, thereby causing blurred vision at reading distance.

It is not a disease or an illness, it’s a natural part of the aging process, and it happens to just about everyone around the age of 40.
