Contact Lenses: Good Choice for Kids?
The biggest concern parents have about contact lenses for their kids is, "Is
my child old enough to wear contact lenses?"
In reality, there's no one answer. Physically the eyes can tolerate contact
lenses at a very young age. Some babies are fitted with contact lenses due to
eye conditions present at birth. What parents are really asking is, "Is
my child mature enough to wear contact lenses?" eye care practitioners
can offer guidelines and recommendations, but only parents can answer that question.
If you're considering contact lenses for your child, take a look at how your
child handles other responsibility. Does he take out the trash, care for the
dog or follow through with school or other projects? If your child needs frequent
reminders for everyday chores, he may not be ready for the responsibility of
wearing and caring for contact lenses. But if he handles such duties well, he
may be an excellent candidate for contact lenses.
Children are naturally great contact lens wearers if they accept the responsibility
for them. They adapt well to wearing the lenses due to their flexible personalities.
Kids also develop fewer complications than adults. Younger people usually heal
faster and have stronger immune systems. Plus, children tend to follow instructions
better than adults, so they have fewer problems with overwearing the lenses
or not using the correct care solutions.
Great for Sports
Sports and contact lenses are a great combination for all athletes, including
smaller athletes. Contact lenses may be a safer vision option than glasses for
recreation use. Polycarbonate lenses are a must, but frames are more vulnerable
to breakage. Many contact lenses, especially rigid gas permeable lenses, offer
better optics than eyeglasses. This leads to clearer vision and better sports
performance. A baseball player might see the ball a few milliseconds sooner
with crisp vision from contact lenses. Better peripheral vision also comes from
contact lenses, which leads to a superior performance.
It's much easier to play sports with contacts than with glasses.
Controlling Nearsightedness
Myopia control is another great reason for children to wear contact lenses.
If your child is nearsighted, consider fitting him with rigid contact lenses
to slow the progression of myopia. Although the concept is controversial, many
eye care practitioners believe that rigid contact lenses may prevent your child
from reaching the full amount of nearsightedness wearing glasses or soft contact
lenses would bring.
Building Self-Esteem
Contact lenses can do wonders for your child's self-esteem. Many kids would
opt for contact lenses over glasses, mainly for cosmetic reasons. They don't
like the way they look while wearing glasses. Physical appearance can be dramatically
altered by switching from glasses to contact lenses. In many cases, this physical
change prompts a self-confidence and self-esteem surge in the child. School
performance and participation may also increase after switching to contact lenses.
Amazingly, two thin pieces of plastic may breathe new life into a previously
reserved child.
Keep in mind that switching your child from glasses to contact lenses does
not have to be a permanent decision. If your child does not adapt well, or is
not up to the responsibility of wearing and caring for contact lenses, your
eye care practitioner will not hesitate to recommend glasses as a safer means
for vision correction. You may speak to the eye care practitioner as well if
you feel your child is not handling the switch well. Contact lenses can always
be tried again at a later date.

Corneal Abrasion
A corneal abrasion is an injury to the front surface of the eye.
The injury can occur when a foreign object gets in the eye, when the cornea becomes scratched or even from rubbing the eyes very hard.
The cornea is very sensitive.
Depending on the location and depth of the injury, it can be very painful and even sight threatening, resulting in permanent visual impairment.
Treatment is important to prevent infection within the injured cornea.
The medication that the doctor prescribes will help to heal the cornea and prevent the risk of infection.
It is important to follow the doctor's instructions so that the cornea heals properly.
Small abrasions can heal within 24 hours but other, more severe abrasions can take up to several weeks to heal.
There are different ways to treat this injury.
The doctor will probably prescribe eye drops and / or ointment.
You may need to wear a special contact lens overnight or longer in order to help with healing.
Sometimes a patch may need to be worn on the eye overnight.

Dry Eye
Dry eye is a common condition that occurs when the eyes
do not produce enough tears or produce tears that do not have
the proper chemical composition. If untreated, dry eye can
damage eye tissue.
The most common symptoms are:
· A sandy, gritty sensation.
· Irritated, scratchy or dry eyes.
· Redness of the eyes.
· A burning sensation of the eyes.
· A feeling of a foreign body in the eye.
· Blurred vision.
· Excessive watering (reflex tearing that flushes normal lubricating
oils).
The first line of treatment is the use of lubricating drops
(artificial tears). Your doctor will prescribe specific eye
drops that can be purchased over-the-counter. They should
be used regularly, each day to obtain relief.
Medications are available for those who have a chronic problem
which does not respond to artificial tears. There are also
nutritional supplements that are helpful for dry eye.
One of the most effective treatments is punctal occlusion.
A tiny plug is inserted into the puncta (a small hole in the
eyelid), impeding the outflow of natural tears. This procedure
takes only a few minutes and can be done in the doctor's office.

Protecting Your Eves From UV Radiation.
The sun, a ball of fire some 93 million miles away, supports
all life on our planet. But, its life giving rays also pose
dangers.
The principal danger posed by the sun is in the form of ultraviolet
radiation, or for short, UV radiation. UV radiation is a component
of solar energy, but it can also be given off by artificial
sources like welding machines, tanning beds and lasers.
You are probably aware of the danger posed by UV radiation
to your skin, but you may not realize that exposure to UV
radiation can harm your eyes and affect your vision as well.
UV radiation is divided into UV-A, UV-B and UV-C. UV-C
is absorbed by the ozone layer and does not present any
threat (man made sources of UV-C, like electric welding
arcs, are very harmful to the eyes, if you do not use the
proper protection). That's not true of UV-A and UV-B. More
and more scientific evidence is showing that exposure to
both UV-A and UV-B can have damaging long and short term
effects on your eyes and vision.
If you are exposed, unprotected, to excessive amounts of
UV radiation over a short period of time, you are likely
to experience an effect called photokeratitis. Like a "sunburn
of the eye" it may be painful and you may have symptoms
including red eyes, a foreign body sensation or gritty feeling
in the eyes, extreme sensitivity to light and excessive
tearing. Fortunately, this is usually temporary and rarely
causes permanent damage to the eyes.
Long term exposure to UV radiation can be more serious.
A number of scientific studies and research have shown that
exposure to small amounts of UV-B radiation over a period
of many years may increase your chance of developing a cataract
and can cause damage to the retina, the nerve-rich lining
of your eye that is used for seeing. Damage to the retina
is usually not reversible.
The effects of UV radiation are cumulative. This means
the longer your eyes are exposed to UV radiation, the greater
the risk of developing conditions such as cataracts in later
life. Therefore, you should wear quality sunglasses that
offer good protection and a hat or cap with a wide brim
whenever you are working outdoors, participating in outdoor
sports, taking a walk, running errands or doing anything
in the sun.
To provide protection for your eyes, your sunglasses
should:
· block out 99 to 100 percent of both UV-A and UV-B radiation;
· screen out 75 to 90 percent of visible light;
· be perfectly matched in color and free of distortion and imperfection;
and
· have lenses that are gray, green or brown.
Polycarbonate lenses are a must for your sunglasses if
you participate in potentially eye hazardous work or sports.
These lenses provide the most impact resistance.
If you spend a lot of time outdoors in bright sunlight,
wrap-around frames provide additional protection from the
harmful UV radiation.
Don't forget protection for children and teenagers. They
typically spend more time in the sun than adults.
UV Radiation Checklist
If one or more of the following factors fits you, you could
be in a higher risk category for damage to eyes from UV radiation:
Do you spend a great deal of time outdoors?
Do you spend time skiing, mountain climbing or at the beach?
Do you use a sunlamp or tanning parlor?
Do you live in the mountains or the U.S. Sunbelt? :
Are you a welder, medical technologist or do you work in
the graphic arts or in the manufacture of electronic circuit
boards?
Do you take prescription or over the counter drugs that can
increase your sensitivity to UV radiation (check with your
optometrist, pharmacist or physician)?
Have you had cataract surgery in one or both eyes?
Be sure to see your doctor of optometry once a year for a
thorough eye examination. It is a good way to monitor your
eye health, maintain good vision and keep track of your UV
radiation protection needs as well as new advances in that
protection.

Eyelid Problems.
The eyelids perform many important functions, including protecting
and lubricating the eye, producing oil secretions, and helping
to drain away tears. The following conditions are usually
not serious and can often be easily treated. However, if left
untreated, they can be uncomfortable, unattractive, and can
lead to more serious problems. Eyelid problems can affect
the upper and/or lower eyelid in one or both eyes.
Blepharitis
Blepharitis is a chronic or long term inflammation of the
eyelid margins (the edges of the eyelids), often caused by
bacteria around the lashes and outer tissues of the eye.
Symptoms can include swelling of the lid margin, irritation,
sensitivity to light, itching, burning, redness along the
lid margin and redness of the eyeball itself. There is often
crust or roughness along the lid margin and/or possibly dandruff
on the lashes. This can be worse in the morning upon awakening.
Patients who wear contact lenses will often experience these
symptoms to a greater degree, as lenses will seem dry.
Treatment
In most cases, good eyelid hygiene and daily cleaning of
the eyelid margins will control blepharitis. Eyelid hygiene
is particularly important upon awakening because bacteria
builds up during the night. In more severe cases, it may be
necessary to combine eyelid hygiene and medication for good
control. In cases where the conjunctiva (the front surface
of the eye) is affected, the doctor may prescribe additional
treatment.
Chalazion
A chalazion results from a blockage of one or more of the
small oil producing glands found in the upper and lower eyelids.
Symptoms are inflammation and swelling in the form of a round
lump within the eyelid that may or may not be painful. If
the chalazion becomes infected, the eyelid can become swollen,
inflamed and more painful.
Treatment
A chalazion may be treated by applying warm compresses. At
times this condition may require additional treatments that
your doctor will prescribe.
Stye
A stye is a bacterial infection of one of the eyelid glands
near the lid margins, at the base of the lashes. This forms
a red, sore lump similar to a boil, causing pain and inflammation.
Treatment
Styes are usually treated with warm compresses. Antibiotic
and /or steroid eye drops or ointments may also be needed.

Computer Vision Syndrome.
Computer Vision Syndrome (CVS) is a complex optical and musculoskeletal
disorder related to near work during computer use.
The most common symptoms of CVS include:
· Headache.
· Loss of focus / blurred vision.
· Double vision.
· Dry, burning, tired eyes.
· Muscular strain.
· Excessive tears.
· General fatigue.
· Excessive blinking/squinting.
· Overall stress.
· Neck or shoulder strain/pain.
As an eye and vision problem, some individuals react with
more difficulty focusing on characters on a computer screen
as opposed to reading printed material on paper.
Treatment is varied and complex with different solutions
for different individual's needs. For optimum patient comfort
and performance, it is usually necessary to use a specific
computer correction. Your optometrist will assess your optical
needs. There are a wide variety of lens styles available,
ranging from single vision computer lenses to progressive-add
bifocals, which can aid in achieving proper focus. There are
also many different lens materials and treatments (i.e. tints
and anti-reflective coatings) to assist with comfort.
Your doctor will be testing your eyes to help find which
solution works best for you. Some of these tests might include:
Detailed Refraction - a measurement
of your visual system's focusing power needs.
Binocular Vision Testing - an evaluation
of your I eyes' efficiency in working together at different
distances.
Dynamic Retinoscopy - an evaluation
of your eye's focusing system function for near tasks.
Tear Assessment - an evaluation of your tear's quantity and
quality.
Studies show that about three-quarters of computer users
experience the symptoms of CVS. The good news is that the
eye and vision symptoms, as well as other problems of CVS,
can usually be alleviated by good eye care and/or by changes
in the work environment.
Eye Breaks
· Refocus eyes away from the monitor to across the room for
5 seconds every 15 minutes of monitor viewing. Look at objects
that are varying distances from your computer.
· Perform several rapid and quick blinks to the eyes several
times to rewet and refocus during this eye break. Application
of artificial tears or rewetting drops for contact lens wearers
at this time would be beneficial.
Workstation Adjustments
· Ambient lighting should be available. Avoid harsh brightness
changes from the computer monitor to the room.
· Minimize screen glare by repositioning the computer monitor
or source of light to avoid glare and light reflections or
consider an anti-glare screen.
· Place monitor directly in front of you, not off to one side.
Adjust monitor sharpness, contrast (adjust to individual comfort),
brightness (match room brightness), distance (20 inches to
26 inches), and viewing angle (approximately 15 degrees from
eyes to monitor center).
A larger monitor with higher resolution and refresh rate (70Hz
or higher) than your current monitor may also be helpful.
· Adjust your chair so that both feet touch the ground with
knees approximately 90 degrees to the floor and elbows approximately
90 degrees to the keyboard. Allow for comfortable thigh support.
· Exercise when sitting with various stretches and joint rotation.
Standing up and moving about is also helpful to keep your
blood circulating.

Using Your Eyes and Your VDT
It's 11:30 in the morning. You've been working at your video
display terminal (VDT) since 9:00 AM. Your eyes feel irritated
and fatigued, your vision is blurry and you still have several
hours of work ahead of you.
The symptoms that you are experiencing are common among people
who work with VDTs. They may be a result of the way that you
use the equipment and furnishings in your workstation. But
they may also be, at least partly, the result of a vision
problem. Anytime you experience symptoms like headaches, eye
strain, blurred vision, eye irritation, double vision, excessive
tears or dry eyes, pain in the eyes or excessive blinking
or squinting, you should visit your doctor of optometry for
a comprehensive eye examination. And, when you do, be sure
to tell the doctor about the VDT work that you do.
After you have had a comprehensive eye examination, there
are a number of things that you can do to arrange and use
the elements of your workstation to eliminate or minimize
discomfort.
Adjusting your chair
Many times, your chair can be adjusted to make your work
station much more efficient and comfortable. For instance:
· Your feet should be flat on the floor (or on a slightly angled
foot rest) with your knees bent close to or greater than 90
degrees.
· Your chair should support your legs without excessive pressure
on the back of your thighs.
· Your back should be snug against the seat to fit your spinal
contour. Your thigh to trunk angle should be 90 degrees or
greater.
· The distance from the front of your chair to the hollow of
your knee should be 2" toc4" inches.
· Your wrist and hand should extend nearly straight from the
elbow to the home row of the keyboard.
Setting up your work surface
Consider the following suggestions to make sure the height
of your work surface and the amount of leg room it provides
are "comfortable."
· For most people, the amount of leg room below the work surface
should be about 25" high by 27" wide by 27"
deep. Larger people will require more space.
· A commonly preferred work surface height for VDT use is about
26" as opposed to conventional 29" of most tables
or desks.
Using your VDT and Keyboard
The following suggestions will help you arrange your VIDT
screen and your keyboard to allow you to work most productively
and comfortably: |
· Locate your VDT 16" to 30" from your eyes, depending
on the size of your VDT and your individual vision conditions.
Many people find 20" to 26" most comfortable.
· The top of the VDT should be slightly below a horizontal eye
level. Tilt the top of the VDT away from you at a f 0 degree
to 20 degree angle.
· Place document holders close to your screen within the same
viewing distance. Keep your keyboard and VDT in line.
· Keep your VDT screen free of fingerprints and dust. Both can
reduce clarity.
· Adjust your keyboard so it does not lie flat.
VDTs and lighting
To improve visual efficiency when using your VDT:
· Try to match the brightness of the surroundings to that of
the VDT screen. Overall room light should be about 20 to 70
foot candles, which is about half the level of normal office
light.
· The contrast between the characters on the VDT screen and
the screen background should be high.
· Minimize reflected glare on your VDT screen by using window
treatments, dimmer switches on lights and anti-glare screens.
· Position your VDT screen perpendicular to windows or other
bright light sources to reduce the likelihood of glare. To
locate the source of glare, hold a small mirror on your VDT
screen. The reflection will help you determine the origin
of the glare.
Working efficiently
Human eyes were made for most efficient operation at a distance,
but if you use the suggestions made here and those made by
your doctor of optometry you will be able to use your VDT
more comfortably and productively.

Don't Skip Your Contact Lens Exam
"Many people assume they can buy contacts from any available source and put them on," says Dr. Pegueros.
"This could result in discomfort and injury to your eyes if your lenses aren't accurately prescribed and properly fitted. Remember that contacts require a prescription because they're medical devices. You should treat them with the same caution and care as any other medicine."
If you're interested in wearing contacts, you should understand the difference between a routine, annual eye exam and an exam meant specifically to fit you with safe, reliable contacts, says Dr. Pegueros.
"During a routine exam, the doctor will check for overall eye health and may write a prescription for glasses without the need for much follow-up," he says.
"Contacts are different because they rest right on the eye," he adds.
"They can affect its shape and comfort if they aren't fitted properly. If they don't work right, the lenses could cause abrasion of the eye's surface and even an eye infection.
"You also need to understand how to properly place the contacts on the eyes and when to wear and replace them. Getting these things right requires an annual evaluation and fitting from your eye doctor."
If you're thinking about contacts, Dr. Pegueros recommends these steps:
Schedule a contact lens exam with your eye doctor. You can describe your vision goals and discuss the type of lenses you might wear and the length of time you will wear them before replacing them.
Learn how to put in your new lenses and how to clean and store them.
Schedule a follow-up exam 30 to 60 days after you start wearing the contacts.
Says Dr. Pegueros, "Taking the time and trouble to get the right contacts for your eyes is worth it. You'll see better and will enjoy the peace of mind knowing your contacts are healthy and safe for your eyes."

You're Never Too Old to See Better
Ask doctor Pegueros, to describe the latest treatments that help senior citizens see better, and he'll tell the story of a 66-year-old patient named Manny who improved his eyesight with laser vision correction surgery.
"My friend Manny wanted to retire and do some of the things he enjoys most, such as traveling, but his near-sightedness had become a problem," says Dr. Pegueros.
After carefully examining his friend's eyes, Dr. Pegueros recommended LASIK, a brief and virtually painless laser procedure to correct his nearsightedness permanently.
"Manny's been going stronger than ever since the procedure," he says. "He's extremely active at age 72 — and most of the time he doesn't even wear glasses!
"More and more people in their early- to mid-60s are benefiting from this proven technology," he says. "The procedure usually takes less than a half hour. In my experience, most of the seniors who've been through it are pleased with the results."
LASIK worked for Manny, but Dr. Pegueros cautions that it isn't the solution for all older Americans. Fortunately, other techniques are available to help them improve their eyesight and remain active. Some of the most exciting vision-enhancing options include:
Extended-wear soft contact lenses: Launched about a year ago, comfortable, extended-wear soft contacts can be left in place night and day for up to a full month. This eliminates most of the hassle (washing, rinsing, soaking, etc.) of wearing contacts. The new lenses can remain in the eye for longer periods because they allow large amounts of oxygen to reach the corneal surface. This helps prevent germs from causing infections under die contacts.
Bifocal contact lenses: A growing number of seniors are enjoying the freedom that comes with discarding their bifocal glasses. Bifocal contacts allow the wearer to read a book up close or focus on a distant object simply by shifting his or her gaze.
Progressive lenses: Sometimes described as "no-line bifocals," these eyeglass lenses allow wearers to see close-up objects (such as the pages of a book) better, while also improving vision at middle and far distances. Because they correct vision all along the range of sight — with a progressively engineered lens that provides a seamless transition from near to faraway images — the glasses eliminate the cumbersome split-vision effect so often created by bifocals. Many wearers also say they look much better than the old-fashioned bifocals.
Dietary supplements: Many senior citizens are using food supplements — including antioxidant vitamins (primarily A, E and C) and lutein (found in spinach) — that may slow down age-related conditions such as macular degeneration and cataracts.
Low-vision aids: Many of the 14 million older Americans who struggle with partial sight loss (also called low vision) are turning to vision-enhancing tools to remain active. These include telescopic adapters that attach directly to glasses and TV magnification systems that provide enlarged images of books, newspapers and other objects.
"At your annual eye exam, make sure you talk to your doctor about the options best suited to your lifestyle," advises Dr. Pegueros.
