Presbyopia is a condition in which the lens of the eye loses its ability to focus, making it difficult to see objects up close.
Presbyopia is a condition in which the lens of the eye loses its ability to focus, making it difficult to see objects up close.
Causes:
In the young eye, the lens needs to change its length or shape to focus on objects that are close. The ability of the lens to change shape is called the elasticity of the lens. This elasticity is slowly lost as people age. The result is a slow decrease in the ability of the eye to focus on nearby objects.
People usually notice the condition at around age 45, when they realize that they need to hold reading materials further away in order to focus on them. Presbyopia is a natural part of the aging process and it affects everyone.
Symptoms:
Decreased focusing ability for near objects
Eyestrain
Headache
