Presbyopia is a vision condition in which the crystalline lens of your eye loses its
flexibility, which makes it difficult for you to focus on close objects.
|
Presbyopia may seem to occur suddenly, but the actual loss of flexibility takes place over
a number of years. Presbyopia usually becomes noticeable in the early to mid-forties.
Presbyopia is a natural part of the aging process of the eye. It is not a disease and
it cannot be prevented. Some signs of presbyopia include the tendency to hold reading
materials at arm's length, blurred vision at normal reading distance, and eye fatigue
along with headaches when doing close work. A comprehensive optometric examination will
include testing for presbyopia.
|
To help you compensate for presbyopia, your optometrist can prescribe reading glasses,
bifocals, trifocals or contact lenses. Since presbyopia can complicate other common vision
conditions like nearsightedness, farsightedness, and astigmatism, your optometrist will
determine the specific lenses to allow you to see clearly and comfortably. Laser eye surgery
cannot improve presbyopia.

What are my choices?
|
Usually, the treatment for presbyopia is prescription eyeglasses to help the eye accommodate
for close-up work. Prescription lenses (reading glasses) help refract light rays more
effectively to compensate for the loss of near vision. If you do not have other vision
problems, such as nearsightedness or astigmatism, you may only need glasses for reading
or other tasks done at a close range. If you have other refractive errors, such as
nearsightedness, bifocal or progressive addition lenses (in which the power of the lens
changes gradually towards the bottom to allow reading, without the reading portion of the
bifocal lens obviously visible) are often prescribed.

Symptoms of presbyopia include:
Decreased focusing ability for near objects - eyestrain - tired eyes - headache
|
As we age, body tissues normally lose their elasticity. As the lenses in our eyes lose some
of their elasticity, they lose some of their ability to change focus for different distances.
The loss is gradual. Long before we become aware that seeing close up is becoming more
difficult, the lenses in our eyes have begun losing their ability to flatten and thicken.
Only when the loss of elasticity impairs our vision to a noticeable degree do we recognize
the change. With presbyopia, the crystalline lens of your eye loses its flexibility, which
makes it difficult for you to focus on close objects. Presbyopia may seem to occur suddenly,
but the actual loss of flexibility takes place over a number of years. Presbyopia usually
becomes noticeable in the early to mid-forties. Since the effects of presbyopia continue to
change the ability of the crystalline lens to focus properly, it may worsen over time.
Presbyopia is a natural part of the aging process of the eye. It is not a disease and it
