General Eye Care
What is an Optometrist?
Optometrists are the primary health care
professionals for the eye. Optometrists examine,
diagnose, treat and manage diseases, injuries and disorders of
the visual system, the eye, and associated structures, as well
as identify related systemic conditions affecting the eye.
They work closely with primary care physicians, other health
care providers and specialists to coordinate care.
How often should I have my eyes
examined?
People often associate the need for an eye exam with how well
they are seeing or when they need to replace their eyeglasses.
Even though it is important to see well, undesirable changes
can occur which go undetected and unnoticed by patients
because these changes do not adversely affect vision in their
early stages. Do not rely on changes in your vision or on the
need for new eyeglasses to remind you of your next exam.
Follow the advice of experts and have your eyes examined
yearly. Those with a family history of eye disease, diabetic
patients, taking medications that may have side effects on the
eye and anyone whose overall health is poor may need their
eyes examined more often.
What is 20/20 vision?
It is a measurement of sight. If you can see a letter 8.7mm
tall at 20 feet than you have 20/20 vision. If you have to be
twice as close, say 10 feet away to see this same object than you have
20/40 vision.
What is included in an eye exam?
A complete eye exam is more than a vision test. Your eye
examination includes computerized state of the art
instrumentation for testing, so the doctor has the best
information to evaluate the health of your eyes. The exam
includes testing for glaucoma, cataracts, peripheral vision
and all other eye diseases. In addition to a complete eye
health evaluation your exam will determine what prescription
is needed for the best possible sight.
What is nearsightedness?
Nearsightedness is a vision condition in which objects
far away appear blurry, but objects up close appear clear.
This occurs if your eyeball is too long or if the front curve
of your eye is too steep. Nearsightedness is correctable with
glasses or contact lenses.
What is farsightedness?
You are farsighted if objects at a distance appear
clear, but you find it difficult to bring close objects into
sharp focus. Farsightedness can cause eyestrain, headaches,
fatigue or difficulty in concentration while reading or
performing other near-vision activities. It occurs when the
eyeball is too short or the front curve of the eye is too
flat. Regular eye examinations are recommended to check for
this, as it is often missed in school screenings.
What is astigmatism?
Astigmatism is caused by an irregular shaped cornea, the clear
cover on the front of the eye, or the lens inside the eye.
Instead of being round like a basketball, it is more
oval-shaped like a football. Astigmatism causes the light to
not focus properly on the back of the eye, resulting in
blurred vision. This condition can be corrected with glasses
or contact lenses.
Why did I have to start wearing reading
glasses or bifocals in my forties?
The lens of your eye grows your whole life. Eventually it
begins to harden and loses some elasticity, making it
difficult to focus up close. This is called presbyopia and
bifocals enable you to see at a distance and up close again.
Presbyopia can also be corrected with contacts in many
patients.
Can eye exercises improve my vision?
You can train your eye muscles to work better together
and correct problems like strabismus crossed eyes which
involves training the muscles that align the eye.
Can my eyes get "sunburned"?
Yes! Two examples of this are "snow blindness" and
"welder's flash". Outdoor enthusiasts and those with sensitive
eyes should invest in quality sunglasses with an ultraviolet
filter to block harmful UV radiation from the sun. Contact
lens wearers are especially sensitive to bright light. They
should always wear a good pair of non-prescription sunglasses
with their contacts when they are outdoors.
Eye Diseases And Eye Disorders
What are cataracts?
Cataracts are the cloudiness of the crystalline lens of
the eye.
A clouded lens interferes with light reaching the retina,
causing blurred vision.
What is Eye Pressure?
The eye has a certain internal pressure not unlike a
balloon. Rather than being filled with air the eye is filled
with a watery substance (aqueous) and thick, oily or jelly
like substance (vitreous). It is vital to check eye pressure
yearly to help detect Glaucoma.
What is Glaucoma?
Glaucoma is a disease in which the eye pressure causes
nerve damage and can result in blindness. Open angle glaucoma
can occur painlessly and slowly. It can gradually destroy your
vision without your knowledge. It is treatable with eye drops
or surgery.
What is a "lazy eye"?
It is called amblyopia, but one of the best definitions
of a lazy eye is an eye that does not see well. If it is
diagnosed before the age of five or six, amblyopia can often
be corrected with eyeglasses and patches over the good eye to
force the "lazy eye" to "learn" to focus. Note: Some people
refer to a lazy eye as one that turns in or out, in a
direction different than the focusing eye. That is actually a
condition called strabismus.
Eyeglasses
Will wearing eyeglasses make me
dependent on them?
No. Both glasses and contact lenses allow you to see
comfortably. When you remove them, you see less comfortably.
This contrast is what makes some people believe their vision
is worse for wearing glasses. Corrective lenses won't make
your vision problems go away, nor will they worsen them. They
only correct the symptoms.
What are bifocals? Who needs to wear
them?
Bifocals use two different powers in one lens.
Typically, the upper portion of the lens if used for distance
vision and the lower portion is used for viewing objects up
close. Bifocals correct for a decreasing ability to focus, a
problem that sneaks up on just about everybody as they age. It
is likely that most people will need bifocals, or what is
known as progressive lenses, at some point in their lives.
What are progressive lenses?
Progressive lenses are sometimes called a no-line
bifocal. The focus of this lens changes gradually as you look
down through the bottom of it. This lens gives vision at
distance, intermediate and near without a line in the lens.
Contact Lenses
Can I wear contact lenses?
Most people are able to wear contact lenses whether
they are nearsighted, farsighted, have astigmatism or have
lost the ability to read up close.
I have worn contact lenses for years but
now I cannot wear them for as long as I used to. Why?
The more you wear contact lenses, the less tolerant
your eyes become to the protein deposits that naturally
collect on the lenses. Your eyes can actually become allergic
to those deposits. That is why wearing fresh contact lenses is
essential.
What are soft contact lenses?
Soft contact lenses are made from a soft pliable
material that is hydrophilic (water loving). This means the
contact lens material holds a certain amount of water within
itself.
What are daily wear contact lenses?
Daily wear contact lenses are designed for the purpose
of wear during waking hours. They are not to be worn while
sleeping. You can get these type of lenses in daily, weekly or
monthly replacement. They are designed for the optimum health
of your eyes as well as to meet your lifestyle needs.
What are extended wear contact lenses?
Extended wear contact lenses are designed for the
purpose of sleeping overnight in and wearing continuously for
one week or up to one month depending on the overall health of
the patients eyes and the type of extended wear lens.
What is a rigid gas permeable contact
lens?
A gas permeable contact lens is made of a plastic
polymer material that is flexible and permeable to oxygen.
They are generally smaller and less flexible than a soft lens.
For some patients these lenses provide better and more stable
vision than a soft contact lens.
