Care Facts and Myths
Reading in dim light is harmful to your eyes.
It is not harmful to watch a
welder or look at the sun if you squint, or look through narrowed eyelids.
Using a computer, or video
display terminal (VDT), is harmful to the eyes.
If you use your eyes too much,
you wear them out.
Wearing poorly-fit glasses
damages your eyes.
Wearing poorly-fit contacts
does not harm your eyes.

eyes checked until you are in your 40s or 50s.
Safety goggles are more trouble
than they're worth.
It's okay to swim while wearing
soft contact lenses.

Although reading in dim light
can make your eyes feel tired, it is not harmful.
Even if you squint,
ultra-violet light still gets to your eyes, damaging the cornea, lens and
retina. Never watch welding without wearing the proper protection. Never look
directly at an eclipse.
Although using a VDT is
associated with eyestrain or fatigue, it is not harmful to the eyes.
You can use your eyes as much
as you wish-they do not wear out.
Although a good glasses fit is
required for good vision, a poor fit does not damage your eyes.
Poorly fit contact lenses can

your eyes are checked regularly by your ophthalmologist if you wear contact
There are several asymptomatic,
yet treatable, eye diseases (most notably glaucoma) that can begin prior to
Safety goggles prevent many
potentially blinding injuries every year. Keep goggles handy and use them!
Potentially blinding eye
infections can result from swimming or using a hot tub while wearing contact
Children do not outgrow truly
crossed eyes. A child whose eyes are misaligned has strabismus and can develop
poor vision in one eye (a condition known as amblyopia) because the brain turns
off the misaligned or “lazy” eye. The sooner crossed or misaligned eyes are
treated, the less likely the child will have permanently impaired vision.
With modern cataract surgery, a
cataract does not have to ripen before it is removed. When a cataract keeps you
from doing the things you like or need to do, consider having it removed.
Cataracts cannot be removed
with a laser. The cloudy lens must be removed through a surgical incision.
However, after cataract surgery, a membrane within the eye may become cloudy.
This membrane can be opened with laser surgery.
The eye cannot be transplanted.
It is connected to the brain by the optic nerve, which cannot be reconnected
once it has been severed. The cornea-the clear front part of the eye-can be
transplanted. Surgeons often use plastic intraocular lens implants (IOL's) to
replace natural lenses removed during cataract surgery.
An ophthalmologist is a
medical doctor (M.D.) or doctor of osteopathy (D.O.), uniquely trained to
diagnose and treat all disorders of the eye. An ophthalmologist is qualified to
perform surgery, prescribe and adjust eyeglasses and contact lenses, and
An optometrist (O.D.) is
not a medical doctor, but is specially trained to diagnose eye abnormalities,
and prescribe, supply and adjust eyeglasses and contact lenses. In most states,
optometrists can use drugs to treat certain eye disorders.
An optician fits,
supplies, and adjusts eyeglasses and contact lenses. An optician cannot examine
the eyes or prescribe eyeglasses or medication.
