My family doctor checks my vision during my annual physical. Do
I need another eye exam?
The doctor only checks for your ability to read an eye chart. If
you can't, he will refer you to an Eye Doctor for further evaluation. However,
your family doctor does not check for glaucoma, the leading cause
of blindness in the United States. In addition, your
family doctor most likely does not thoroughly examine the internal
structures of your eye. It is here that an Optometrist
can see signs of hypertension (high blood pressure) and diabetes, atherosclerosis (the hardening of blood vessels), and certain cancers. In
all, more than 40 systemic diseases and disorders can be detected
in an eye examination alone. In addition, our vision
changes as we grow older due to the natural changes in the eye. It
becomes increasingly more difficult to focus on near objects as
we pass forty years old. This condition, Presbyopia,
requires a special prescription for reading and near work, and
is diagnosed using a special near-point eye chart not commonly
found in general practitioner's offices. Eye exams
are an imperative preventive step in maintaining general health
and optimum visual acuity. |
What are cataracts?
The natural aging process effects the eye as it does every
other part of the body. As we age, the lens in the
eye becomes hazy and cloudy. The lens focuses images
on the light sensitive nerve endings (the retina) in the back
of the eye. When it becomes cloudy, sharp images cannot
be accurately focused. The symptoms of cataracts often
go unnoticed because the change is gradual. For this
reason, it is very important to have a regular eye exam to help
ensure early detection of cataracts. There is good
scientific evidence now to lead eye doctors to the conclusion
that the development of cataracts is hastened by exposure to Ultra
Violet radiation. For this reason, every pair of glasses
sold by Dr. Tavel's One Hour Optical includes a UV filter to provide
enhanced protection to your eyes. |
Who is susceptible to Glaucoma?
Everyone. But Conditions believed to increase
risk are:
- Age over 45
- Family history of glaucoma
- African descent
- Diabetes, myopia (nearsightedness),
or long exposure to cortisone products
- Previous eye injury

What is glaucoma?
There are no symptoms to warn of glaucoma's attack. The only
way to ensure that the disease does not lead to blindness is to detect it ... and treat it ... in its
early stages. That's why the Dr. Tavel Optical Group has made
it a top priority to educate the public about glaucoma and the critical importance of routine eye exams.
Glaucoma is the leading cause of blindness in the United States. This
condition typically involves an increase in intra-ocular pressure,
but can occur with low or normal pressure as well. It
is typified by certain changes to the optic disk (the place where
the optic nerve enters the eye) and by losses in the visual field
- a narrowing of peripheral vision. It is an easy vision
problems to treat if caught early, yet its damage is irreversible
if left unchecked. Glaucoma usually does not have noticeable
symptoms until it has progressed and caused significant, irreversible
vision loss. Tonometry, which measures the intra-ocular
pressures, and ophthalmoscopy, where the doctor actually views
the inside of the patient's eye, are the only tests to detect
glaucoma in the early stages. Every eye examination
at Dr. Tavel's One Hour Optical includes both tonometry and ophthalmoscopy. The
only way to detect glaucoma in the early stages is through an
annual eye exam. If you have not had an eye exam in
the last twelve months, contact the Dr. Tavel One Hour Optical
closest to you. |
What is presbyopia?

| Normal eye

Eye with presbyopia
- lens becomes less flexible(yellow lens) |
The lens of the eye becomes less flexible as we age. The
lens focuses images on the light sensitive nerve endings (the
retina) in the back of the eye by adjusting it's shape according
to its distance from the image being viewed. As the
lens becomes less flexible, it can no longer adjust itself to
focus on near objects. As you enter your forties, you
may find that you need to hold reading matter farther out in order
to comfortably focus on it. This condition is called
Presbyopia. Bifocals, trifocals, or progressive (no-line
bifocal) lenses are used to correct this condition. If
you have noticed that your arms are not long enough to read, contact
the Dr. Tavel's One Hour Optical closest to you to schedule an
eye examination. |
What are progressive lenses?
Progressive lenses, also known as No-Line Bifocals, are lenses
that include your distance prescription in the upper portion of
the lens. The bottom portion of the lens contains your
near point prescription. There is a "channel"
between the near and distance sections where the power gradually
progresses from your distance, through intermediate to near prescription. This
is accomplished without the tell-tale lines of a standard bifocal. So
not only do you experience more natural vision with a Progressive
lens, nobody but you and your eye doctor need to know that you
are old enough for bifocals! |
Do I need special glasses for athletics even if they are not contact sports?
Protective eyewear should be worn for most sports
to protect your eyes. Just as there are differences
in eyewear for reading or safety goggles, different sports require
various types of eyewear. Skiers should have special
goggles, contact sports require special frames and lenses to protect
the eyes from injury. Every year, you see more and
more professional athletes wearing protective eyewear. Soon,
it may be mandatory in many sports. Every day eyewear
will not afford you protection from injury, and may even make
matters worse. Contact Dr. Tavel's One Hour Optical
to learn more about the type of sports glasses you need. |
Should I consider surgery to correct my vision instead of wearing glasses?
The claims that you will not need glasses after surgery are
not necessarily true. According to the Federal Trade
Commission, some people still need corrective lenses after the
surgery. Also, as we grow older the lens in our eye
changes. Virtually everyone will need glasses, at least
for reading, eventually. In addition, the surgeons
who perform this operation consider 20/40 vision correction to
be good enough. Do you? It may be good enough
to pass a driving test, but it is certainly not satisfactory vision
for optimal performance. Ask your Dr. Tavel Associate
Optometrist for more information on refractive surgery. |
