How old should my child be for a first vision examination?
Examination is recommended by age four; sooner if you notice
crossed-eyes or an apparent problem seeing clearly. Your optometrist
will be able to check your child's ability to see clearly far away and
up close; to change focus from far to near and back; and to use the two
eyes together as a team. It is not necessary for your child to know the
alphabet for these testing procedures.
The optometrist can also detect any tendency toward such vision problems
as nearsightedness, farsightedness or astigmatism. Treatment to prevent
or slow these problems may be started.
In addition, this first examination is important in diagnosing a "lazy
eye" early. Treatment for this is most effective when started early. |

What is the difference between an optician, optometrist and ophthalmologist?
Opticians, optometrists and ophthalmologists all provide eye care
services. Optometrists and ophthalmologists examine eyes and prescribe
vision-correcting lenses. Opticians manufacture and dispense corrective
lenses. For the majority of individuals an optometrist is the doctor of
choice for routine eye health and vision examinations. .

How can I tell if I have glaucoma?
There usually are no symptoms, early diagnosis and treatments are
important to prevent permanent damage. Although there are various types
of glaucoma the most prevalent form is caused by a buildup of fluid in
the eye. When our body makes too much of this fluid or drainage is
blocked, pressure builds inside the eye and can damage internal parts.
By measuring your eye's pressure, examining your optic nerve during an
internal eye health examination and performing other tests, your
optometrist can diagnose glaucoma signs far earlier than you can.
Everyone over 35 or anyone with a family history of glaucoma should have
these tests annually as part of a thorough eye examination. Glaucoma can
usually be controlled with drug or surgical treatment but vision
destroyed by it can not be restored.

Recently I started seeing dark spots and thread-like strands before my
eyes. What causes this? Is it serious?
You are seeing spots and floaters. They are usually harmless but
sometimes they signal a serious eye problem in need of prompt attention.
These include such vision-threatening conditions as retinal detachment,
other retinal disorders, cataracts, diabetes, high blood pressure or
leukemia.
You should, therefore, make an appointment with your optometrist for a
thorough eye examination covering eye health as well as your vision. Be
sure to mention the dark spots and strands you are seeing.
More than likely you are seeing harmless particles of protein or other
natural materials floating in the fluid inside your eyes. But you need a
professional diagnosis. Even if your optometrist diagnoses the spots as
harmless, have them re-evaluated annually or more often, if you notice a
change.

Can working with a video display terminal all day cause eye problems?
There is no conclusive evidence that video display terminal (VDT) work
causes vision problems but it can aggravate existing ones, even minor
ones that do not affect other seeing tasks, such as reading or driving.
This is why the National Institute of Occupational Safety and Health
(NIOSH) recommends that all VDT operators have periodic eye
examinations.
Tell your optometrist you are a VDT operator, describe your VDT work
tasks and mention any eye strain symptoms you are experiencing. Also,
measure the working distance between your eyes and your VDT screen. All
of this is important in determining your on-the-job vision needs.
There are special aids for VDT operators, such as polarizing lenses to
combat glare and wide-band trifocals to give those who need an
intermediate distance lens prescription a full view of the screen. Your
optometrist can also advise about environmental factors and rest breaks
for VDT workers. |

What is a cataract?
A cataract is cloudiness in the lens behind the pupil of your eye.
Cataracts are usually caused by age and can be present at birth,
inherited or caused by injury. Your optometrist can diagnose a cataract during a thorough eye examination. If it progresses, changes in your glasses may be necessary. Cataracts can blur your vision and if it interferes with your daily activities, it can be removed surgically. Good vision can usually be restored with a lens implant. |
