Vision problems may result when various structures in the eye
deteriorate or become diseased. The pupil gets smaller, as
much as a third of its size by age 60 according to one
estimate, altering how (and how much) light passes through
it.
Here are the eye disorders and diseases that most commonly
occur with age:
a. Age-related macular degeneration: This disease is
the leading cause of blindness in people older than 50. Age-
related macular degeneration is marked by damage to the
macula area on the retina, an area that makes clearly
defined, central vision possible.
b. Glaucoma: Glaucoma is a leading cause of blindness
in the United States. This disease is caused by an abnormal
rise in pressure in the fluid-filled chambers of the eyes,
damaging the optic nerve.
c. Cataracts: Another by-product of aging is the
development of cataracts, a condition in which the normally
clear lens of the eye becomes progressively clouded,
ultimately blocking light from reaching the retina or
scattering light and creating glare.
d. Presbyopia: Almost everyone will develop this
condition, typically starting around age 40. In presbyopia,
the normally flexible lens of the eye becomes increasingly
rigid and unable to focus on objects close-up.
e. Night blindness: People with cataracts may suffer
from night blindness, called nyctalopia by medical
professionals. It may be hard for some people to distinguish
certain colors, especially blue from green. Glare from
excessive light scattering caused by cataract may lead to
difficulty driving at night or difficulty navigating the way
to the bathroom in the dark, etc.
To reduce your chances of developing any of these problems at
a younger age, it is important that you have regular eye
examinations beginning at age 40.
