Presbyopia (Eyes over 40 years old)
In the normal eye, light enters through the cornea (the clear
front surface of the eye), passes through the crystalline lens
inside the eye, and comes to a focus on the retina in the back of
the eye.
As we age, the lens inside the eye becomes less flexible.
Presbyopia (Greek for "aging eyes") is an age-related condition in
which the crystalline lens loses its elasticity and its ability to
focus on near objects. This refractive error occurs naturally in
men and women over the age of 40.
Presbyopia is usually corrected with reading glasses (whether
over-the-counter or prescription) or contact lenses, but it can
also be treated surgically.
