Presbyopia is a normal
vision condition in which the crystalline lens of the eyes loses its
flexibility. This results in progressive difficulty in focusing on close
objects.
The focus lens inside
the eyes, crystalline lens, will start to change with normal aging, this change
causes the lens to harden and lose some of its elasticity and therefore some
focusing ability.
The development of this
condition varies from person to person. Although presbyopia may seem to occur
suddenly, the actual decline takes place over the course of many years. It
usually becomes apparent to people in their early to mid-forties.
Signs and symptoms
include the tendency to move reading material away from you to make it clearer.
Also holds reading material at arm’s length, blurred vision at normal reading
distance, and eye fatigue along with headache when attempting to do close work
are all signs of presbyopia.
Unfortunately
presbyopia cannot be prevented; it is, as mentioned before, a natural part of
aging process, the signs can start at varying ages, the eventual change in the
crystalline lens is unavoidable.
Presbyopia is diagnosed
with a comprehensive eye examination by a doctor of optometry will include
testing near vision; this will determine the extent, if any, of presbyopia.
As presbyopia can
complicate other common condition such as nearsightedness, farsightedness and
astigmatism, the doctor will perform other test to determine the specific
lenses that will allow you to see clearly and comfortably for your daily visual
needs.
Treatment: Doctor of
optometric prescribes lenses for near work that include reading glasses,
bifocals, trifocals, progressive addition lenses or contact lenses.
Presbyopia and losing
the flexibility and elasticity of the crystalline lens progress for some time.
These changes will affect the ability of the eyes to focus property. As a
result, periodic changes in your eyeglasses or contact lenses are necessary to
maintain good vision.
After adjusting to your
new eyewear, you should find that you can still do all the things you did
before. Presbyopia will probably not have a significant effect on your
lifestyle at all. You should, however, continue to make sure your eyes are
staying healthy, as recommended by your doctor.
