Presbyopia is an eye condition that usually happens to everyone later in the life. People suffering from presbyopia have a hard time focusing up close.

While hyperopia is commonly known as farsightedness and myopia as nearsightedness, presbyopia might be called “old sightedness.” The term Presbyopia is derived from Greek and Latin origins that mean “old eyes.”

However, presbyopia is generally seen in adults over the age of 40, the exact age of onset varies from person to person and depends on what type of eyeglass prescription (if any) the individual wore before its development.

Many people with myopia (near-sightedness) can read comfortably without eyeglasses or contact lenses even after age 40. Presbyopia may seem to appear immediately, but the actual loss of flexibility in the lens takes place over a period of years.

Presbyopia is not a disease, and it cannot be prevented. There is no cure available for it, but there are many ways to improve near vision.

Causes of Presbyopia

This disease is caused by the aging process. When one is younger, the lens of the eye is flexible and changes its shape in order to focus up close – this process is called “accommodation.”  With age, the lens becomes progressively more rigid and loses its ability to accommodate.

Trauma, occupation, and lifestyle are some of the factors which are responsible, but presbyopia is a natural part of the aging process and will eventually happen to everyone.

Prognosis of Presbyopia

By definition, presbyopia is not a disease it can always be corrected by glasses or contact lenses and will never affect distance vision. It worsens over time.
