Aging Eyes (Presbyopia)
As people age, they often begin to have difficulty focusing their eyes for reading or close work. This is called presbyopia and is the normal aging of the eyes. It usually affects people over the age of forty as the eye starts to lose some of its flexibility.
This condition is easily corrected with eye glasses of increasing strength as a person ages. Bifocal of trifocal lenses may be prescribed to some people with presbyopia who also have other refractive problems such as myopia (near-sightedness), hyperopia (far-sightedness) or astigmatism (distorted vision due to a irregularly shaped cornea).
