Presbyopia Causes

Presbyopia is generally believed to stem from a loss of flexibility and gradual thickening of the natural lens located inside the human eye.It is an age related process. 

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. 

The age related changes appear within the proteins in the lens, thus making the lens less elastic and harder over a period of time. 

Age related modifications also occurs in the muscle fibers that surrounds the lens. With less elasticity, it is difficult for eyes to focus up close.

Presbyopia is a result of an age-related course of action. This differs from astigmatism, nearsightedness and farsightedness, which can be connected on the form with the eyeball and a result of genetic and environmental issues. 

Presbyopia happen inside the proteins inside lens, generating the lens tougher and a smaller amount elastic more than time. Age-related modifications also take location inside muscle fibers surrounding the lens. With fewer elasticity, the eye includes a tougher time focusing up near. Other, a lesser amount of well-liked theories exist too.

Presbyopia is completely different from farsightedness, nearsightedness and astigmatism which are specifically linked with the shape of eyeball and caused by environmental and genetic factors

The lens of the eye needs to change its length or shape to focus on smaller objects, or objects that get closer or farther away. This 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.
