Your Eyes Age as You Grow Older so Don’t Take Yours For Granted!

Wednesday, March 9th, 2011


Your eyes change as you age, and there are things that you can do at every age to help your eyes gracefully, and see your best. Don’t wait until you can’t see before you visit your optometrist. By then, the problem is probably advanced, and may be irreversible. Most eye diseases have no warning signs because you don’t have pain receptors in the retina in the back of your eyes.

First of all, mommies & daddies: start checking your baby’s vision at 6 months old, since vision guides development, and prevents vision loss from a lazy eye. Have your children’s eyes checked every year since there is a strong relationship between learning and vision. If your child isn’t seeing correctly, or they have a tracking or eye teaming problem, this will interfere with their academic and athletic performance. Please do not avoid bringing your children in for an exam at an early age because you are worried about them wearing glasses. You can do a lot more harm by allowing a vision problem to go uncorrected, and we can fit children as young as 8 years old with contact lenses. Check out the CLIP and ACHIEVE studies which show how contact lenses in young children can improve their quality of life. Regarding infants, we can fit them with special contact lenses and teach you how to care for your child’s eyes.

In your 20’s and 30’s many of us feel like we are invincible, but we aren’t. Now is a good time to make sure you are doing the right things for your eyes and your overall health. Be sure to eat healthy foods, stop smoking, wear sunglasses to protect your eyes from sun damage, and find out if a prescription can help you see better at the computer, driving, or playing ball. I know this for a fact since I was the Team OD for the Mighty Ducks of Anaheim. The better you see, the better you’ll be!

In your 40’s you start losing the ability to see close up: this is called presbyopia. See your Optometrist about doing eye exercises to keep your eyes flexible so they can zoom in and out between close and near objects. There are even homeopathic remedies you can use to slow down aging in your eyes. And then of course, keep getting your eyes checked EVERY YEAR! 1 of 4 over 40 have some level of vision loss so don’t just sit there – do something about it.

60+ years old: Your eyeballs have been around for a long time, and they start degenerating, just like the skin on your face is aging. Health problems like hypertension and diabetes affects your eyes. Half of us will develop cataracts, and the risk for glaucoma and macular degeneration increases significantly. But you don’t have to take it lying down: eat healthy, have your eyes checked yearly, BEFORE you start to lose vision. There are so many ways your OD can help you keep your eyes healthy, so you can keep enjoying life, and watch your grandchildren, and grandpets (!) grow up.

Let me tell you what to look for:
• Gradual loss of central or peripheral vision
• Distorted vision or loss of color vision
• Dim, blurry, cloudy or foggy vision

Most people spend more time buying shoes or watches than they do caring for their eyes. People look at your EYES when they talk to you, and your shoes don’t help you see how beautiful life is! Your eyes are your most important sense: RESPECT your eyes, and have your eyes checked every year!

I’m a firm believer in wellness and preventive care. Like going to the dentist: don’t wait until a tooth falls out, or like eating right, and exercising keeps your body healthy. It keeps your eyes healthy also, as well as annual eye exams to catch and treat problems before they harm your vision. Your eyes are one part of your body where it’s important to have them checked before you notice vision changes because by then, it may be impossible to reverse any loss.

Why is it harder to read after 40? Presbyopia

Friday, January 7th, 2011

Just when your career and life are really starting to take off, your eyes seem to be slowing down. Reading and viewing close objects becomes progressively more difficult in your 40’s because of a natural aging process called presbyopia.

Presbyopia makes reading more difficult because of a decreased ability to change focus, especially from far to near. As you age, the lens in your eyes becomes more rigid, and the muscles gradually lose their ability to focus at near.

The signs of presbyopia are:
• Small print is difficult to read
• You need to hold things further away to read
• You need more light to read
• Reading is easier without glasses or contact lenses if you are nearsighted

You can slow down the progression of presbyopia by doing several things:
1. Accommodative exercises: focus between a distant and very close target as fast as you can for 5-10 minutes every day. This increases your eye’s focus flexibility, strength and stamina.
2. Homeopathic remedies: This can slow down, and even reverse the aging process of presbyopia and cataracts. We can prescribe these for you after examining your eyes.
3. Wear sunglasses or glasses with an ultraviolet filter to slow down the aging effects of the sun on your eyes, and to minimize wrinkles around your eyes.
4. Taking anti-oxidant supplements to minimize lens oxidation, which can increase the rigidity of your eyes’ focusing lens. Green leafy vegetables, and orange-colored fruits and vegetables are also good sources of anti-oxidants.

Inevitably, you will need a special prescription, or bifocal lens for reading, even if you had refractive surgery. Options to help you read include:
• Progressive lenses (no-line bifocals)
• Reading glasses
• Adjustable computer glasses
• Bifocal contact lenses
• Mono-vision contact lenses or refractive surgery

We practice in a holistic manner, and are always looking for ways to help our patients age gracefully through diet and exercise, not only for your body, but also for your eyes.

Lady Gaga Eyes: Circle Contact Lenses

Friday, September 10th, 2010

Pop culture trends are creating some dangerous vision problems.

Lady Gaga’s fans are putting their vision at risk by attempting to copy her huge, anime-style eyes as seen in the Bad Romance video. Although Gaga’s gigantic peepers were computer generated, fans are copying the look with illegal Circle contact lenses obtained without a prescription on foreign websites.

These contacts are larger than normal lenses and cover more of the sclera or white part of the eye to create an exaggerated appearance of the eyes. They can cause significant, permanent damage to the eye if they do not fit your eyes properly. This requires a contact lens evaluation by an Optometrist. Potential problems include impaired vision, conjunctivitis (pink eye), swelling, redness, corneal abrasion, scarring, and insufficient oxygen due to the larger, tighter contact lenses that allow less tear exchange and oxygen to the eye. No beauty fad is worth damaging your eyes or causing an infection.

There are safe and legal soft contact lenses with the dark limbal ring, but these lenses are going to be discontinued by the manufacturer as of 10/31/10. You do need a prescription for these lenses, and yes, they look fabulous on your eyes!

This You Tube video describing how to create the “big eyes” from Lady Gaga’s video has received more than 9 million views. Many girls who obtain these Illegal Contact lenses do not care for them properly, and use them for longer than they should be worn for which can also hurt your eyes. Remember, contact lenses are medical devices, not make up.

Here’s a recent interview on the KTLA Morning News about this and other related topics.

The Many Causes of Red or Pink Eye

Tuesday, August 3rd, 2010

Conjunctivitis

Pink Eye

A red or pink eye — although usually painless — is visually disturbing. When people look at you, they look mainly at your eyes. People judge your health and well being by how your eyes look.
Eyes look red when blood vessels near the surface of the eye become enlarged and dilated. If you have red eyes, it is important to find out why. Red eyes have several primary causes including: irritation, infection, allergies, or underlying health problems.

There are many possible causes of red eyes; therefore, it is important to have an Optometrist examine your eyes to determine the cause and best treatment. Here are some of the most common causes:

Allergies: Dust, pollen, mold, environmental (smog, pollution, etc.)
Infections: bacterial (may have mucopurulent discharge and crusting), viral (may have runny nose, sinus congestion, swollen eyelids). Both are very contagious.
Sexually transmitted: Herpes Simplex, Chlamydia
Dry Eye: insufficient tear production, hormonal, age, systemic health problems
Excessive UV/sun exposure: tanning beds, sports: skiing, surfing, etc.
Environmental: smog, chemicals, wind, blowing dust
Eye strain: prolonged computer work or visual tasks decreases blink rate
Lack of sleep
Contact Lens wear: wearing contact lenses too long, or not replacing lenses as prescribed
Uveitis: is an inflammation of the middle layer of the eye where most of the blood vessels are. Symptoms include redness, pain, blurry vision, floaters and light sensitivity. Uveitis can be caused by health problems such as autoimmune disorders such as rheumatoid arthritis or ankylosing spondylitis. Uveitis can also be associated with AIDS, psoriasis, ulcerative colitis, herpes zoster, and syphilis. Uveitis should be treated quickly because other complications, such as glaucoma, cataracts, or retinal and choroidal scarring, may occur if it left untreated.
Blepharitis: a chronic infection and inflammation of the eyelids
Lid Lice (Pthiriasis Palpebrarum)
Smoking marijuana, drinking alcohol
Acute Angle-Closure Glaucoma: Acute angle-closure glaucoma is a serious medical emergency and must be treated immediately.
Subconjunctival Hemmorage: It can be caused by a Valsalva maneuver such as hard sneezing, coughing, intense straining, vomiting, trauma, high blood pressure, diabetes and sometimes from certain blood disorder problems
Injury:Corneal abrasion, ocular trauma, sports injury
Corneal Ulcer or Infection: The cornea has no blood vessels of its own. When the cornea becomes infected, surrounding blood vessels enlarge to bring immune system-related cells to help fight the infection.
Frequent Use of Eye Drops: Constant use of one of the “get the red out” eye drops can cause over dilation of the eyes’ blood vessels. A rebound hyperemia effect can occur when you stop using the drops because the body becomes accustomed to being chemical constricted by the eye drops. After the effect of the eye drop wears off, the blood vessels sometimes dilate larger, causing the eyes to appear even more bloodshot

If you have a red or pink eye, see your Optometrist immediately. In case your red eye is contagious, be careful not to spread the infection. Wash your hands often, do not share linens, do not share make up, and do not go swimming. Discard any liquid make up that you are using, and soft contact lenses.

Do not use medications prescribed for someone else, or leftover from an old infection. The medication may not be appropriate for your current condition, and the bottle may be infected from touching the eye during previous use.

If you, or your child, are experiencing other symptoms such as coughing, runny nose, earache, the symptoms may be caused by the same bacteria, and you may need an oral antibiotic in addition to the treatment for your eyes.

The bottom line is that pink or red eyes can be caused by many reasons. Make an appointment immediately with your Optometrist to determine the cause and best treatment for you or your child.

Computer Vision Syndrome: Does Using the Computer Make You Tired?

Saturday, July 17th, 2010

Using the computer more than 2 hours a day is hard on your eyes. Your eye muscles have to stay in focus, track across thousands and thousands of words, and work like a synchronized swim team, or you will see blurry or double. If you have astigmatism, are farsighted, or your eye prescription is different in each eye, this adds more strain to the focusing system. Also, if your eyes don’t work well together (the eyes drift apart due to poor eye muscle coordination from strabismus, convergence insufficiency or excess, and tracking problems), this can cause eyestrain and diminish your productivity also. To see my latest TV interview about CVS, go to: http://www.videowired.com/video/2674864358/

It is more tiring to read from a computer screen than a printed book because the pixels that form the letters are not stable, and have less contrast & definition than books. There is an electron beam that scans the monitor and recharges the illumination of each pixel frequently. Your eyes have to continuously “fill in the gaps” to keep the words in focus which causes fatigue and eyestrain. Printed books are easier on the eyes because the characters are dense and have well-defined edges.

Studies suggest that most computer users experience some level of eye discomfort from computer work; therefore, most people who work on a computer more than a couple hours daily could benefit from prescription computer glasses.

Symptoms of CVS include:
•    Overall fatigue
•    Headaches or eyestrain
•    Dry, burning eyes
•    Double vision
•    Blurred vision
•    Neck and shoulder pain

Treatment:

•    Get your eyes checked because even a small, uncorrected prescription can cause eyestrain and decrease productivity. Glasses prescribed for computers balance the eyes and eliminate the constant refocusing effort. This increases comfort, accuracy and productivity. Computer glasses are not the same prescription as reading glasses which are prescribed for a closer working distance of 14-16”. Most computer screens are set at 20-24” away. Computer glasses may keep your eyes from getting worse (more nearsighted) by reducing excessive focusing strain on the eyes, especially for children and teens whose eyes are still developing.

•    To avoid visible flickering, the Refresh Rate should be set at a minimum of 75Hz

•    Vision Therapy to correct eye muscle problems computer glasses eliminate the constant refocusing effort that your eyes go through when viewing the screen. Vision problems that affect productivity include: Strabismus (esotropia, exotropia), Amblyopia, Convergence problems (convergence insufficiency or excess), Oculomotor Dysfunction (tracking problems), Fusional Instability (impaired ability to fuse the images from both eyes together).

•    Take a 20/20 “eye break”. Every 20 minutes, rest your focusing muscles by taking a 20 second break. Look into the distance, away from your desk and computer for 20 seconds.

•    Correct computer set up: do not have a window in front of, or behind, your computer screen. Overhead lights should be perpendicular to you. Dim the room lights to decrease glare and avoid washing out the computer screen and causing glare. Use a light on paperwork or your desk if necessary, but make sure it’s not pointed at the screen.

•    Use artificial tears to moisturize your eyes if they are dry. Your doctor can also recommend homeopathic remedies and nutrition tips to increase tear production

Technically speaking, if your eyes are tired, or you are tired, have your eyes examined to see if a prescription for Computer Glasses can help you, or if you have an eye muscle or focusing problem, or dry eye problem that is treatable. This will help you be more comfortable and more productive at work, school, and while tweeting on your iPhone or Blackberry!

GLAUCOMA: WAYS TO REDUCE RISK AND KEEP YOUR OPTIC NERVE HEALTHY

Sunday, June 13th, 2010

WHAT IS GLAUCOMA?

Glaucoma results from damage to the optic nerve which can impair vision. Glaucoma is the second leading cause of blindness, and is commonly referred to as the “Silent Thief of Sight” because it damages vision so gradually that you do not notice it until the advanced stages.

It is usually associated with elevated intraocular pressure or reduced blood supply – circulation to the optic nerve. Another mechanism is when the microscopic drainage system in the eye is partially obstructed, the intraocular pressure increases causing damage to the optic nerve. However, even people with normal eye pressures can have glaucoma.

HOW CAN I TELL IF I HAVE GLAUCOMA?

Unfortunately there are usually no symptoms until you have lost vision. Early diagnosis and treatment are the best way to minimize or prevent optic nerve damage, and limit glaucoma-related vision loss which is why we recommend annual eye exams.

Normal Vision without Glaucoma

Loss of Peripheral Vision with Glaucoma

HOW DO YOU TREAT GLAUCOMA?

There is no cure for glaucoma, but continuing treatment can preserve eyesight. Eye drops are usually the first line of treatment followed by laser procedures, surgery, and oral medications. A glaucoma specialist will prescribe the best treatment for your type of glaucoma.

RISK FACTORS FOR GLAUCOMA include:

-    Family history (10X greater risk)
-    African-American descent (6-8X higher risk than Caucasians)
-    Age (although infants can have glaucoma)
-    Thin cornea (front surface of eye)
-    Diabetes, high blood pressure, heart disease, hypothyroidism
-    Severe eye injuries
-    Nearsightedness
-    Prolonged corticosteroid use
-    Elevated intraocular pressure (although people with low pressures can develop glaucoma also)

HOW CAN I REDUCE MY RISK FOR GLAUCOMA, and KEEP MY OPTIC NERVE HEALTHY?

There are several ways to keep your body healthy and help reduce your risk for glaucoma:
-    Regular exercise (40 minutes of brisk walking 3x/week for 3 months can reduce intraocular pressure by 20%)
-    Quit smoking (smoking increases risk of glaucoma 2.9X)
-    Limit caffeine intake
-    Limit YOGA inversion techniques which can increase intraocular pressure
-    Ginkgo biloba (antioxidant that can increase blood flow and promote optic nerve health)
-    Acupuncture
-    Bilberry
-    Green leafy vegetables (i.e. spinach, collard greens, broccoli)
-    Consume other antioxidants such as Vitamin E, C, B12
-    Foods high in magnesium (Ex. Fish, apples, avocados, bananas, dairy)
-    Eat less refined foods (i.e. white bread, pasta, sugar)
-    Eat mainly vegetarian including cold-water fish, and eggs
-    Chrysanthemum tea
-    Chinese herbs (Wu Ling San Teapills, Huang Lian Yang Gin)

Do I Have a Vision Problem if I Can’t See 3D Movies?

Sunday, February 7th, 2010

3D Movie  Audience

Research has shown that up to 56% of those 18 to 38 years of age have one or more problems with binocular vision and therefore could have difficulty seeing 3-D.[i] In addition, about five percent of the population have amblyopia (lazy eye) and/or strabismus (eye turn) which makes 3-D viewing impossible. See my interviews nationally on NBC  and on KTLA:

http://www.ktla.com/videobeta/?watchId=801f6ab5-cbfe-401e-9608-6bc4bddeb8c3

http://www.ktla.com/health/3d-movies-health-vision,0,4561218.story

http://www.youtube.com/user/pkandapr#p/u/6/YIvK5gHw9sc

Unfortunately, not all people are able to see 3 dimensional images (stereovision, stereopsis), or 3D. Many people see a 2 dimensional, or flat world, and don’t know it because they have never experienced the pleasure of seeing in 3D. Vision problems such as strabismus (eye turn), amblyopia (lazy eye), or poor binocular skills (eyes drift apart) can interfere with the ability to see true 3D. In order to see in 3D, your eyes need to work together as a team to align the images from each eye, then the brain fuses the images into a 3 dimensional image. Fusion

For example, the 3-D version of the movie Avatar has two images projected on the screen, each image seen by one eye. The images are then merged into one by your brain. If your eyes don’t work together, it will be very difficult to merge or fuse the images into 3-D. The technology behind the Avatar 3-D effects is based on the premise that the viewer has the ability to see 3-D. If you have poor eye coordination, or a lazy eye, 3D television will also look flat to you (2 dimensional), and objects will not “pop off the screen”.

These vision problems affect more than just your ability to see 3D movies. They also impair depth perception, your ability to know where objects are located in space, eye hand and eye body coordination for driving and sports, and reading efficiency and comfort. Over time, if the eyes do not coordinate and work together, the brain ignores one image to avoid seeing double vision. This results in seeing a flat or 2D world.

But there is hope. Thanks to Optometric Vision Therapy, people who previously could not see 3-D are enjoying every special effect that 3-D movies such as Avatar, and 3-D TV have to offer. There are methods to teach people to see in 3D. Using Vision Therapy and physical aids (lenses and prisms) as “training wheels,” you can eventually learn how to point both eyes to focus on the same space. Visual skills are definitely trainable, so you can learn better eye control and coordination through special Vision Therapy techniques.

What options besides surgery do I have for strabismus (esotropia or exotropia)?

Thursday, December 24th, 2009

This is the number one question I receive regarding strabismus. Most surgeons or ophthalmologists will recommend eye muscle surgery, but cannot guarantee their results.

Most optometrists will recommend Vision Therapy or a type of physical therapy to work on eye muscle coordination and control.

The truth is that there are several options depending on how much you, or your child’s eye is deviating, which direction, how often it drifts, and the age of onset. It’s also important to consider if there are any co-existing neurological factors such as a traumatic brain injury, or acquired brain injury (such as stroke or craniotomy) to determine the potential for improvement.

Surgery alone is never the best option. If you cut the eye muscle, but the brain doesn’t learn how to coordinate the eyes and use them together, the eyes will drift apart again, and another surgery will be necessary. The brain needs to be trained to function as a two eyed system and use the eyes as a team. This will minimize the likelihood of the eyes drifting apart after surgery, and will maximize cosmetic alignment as well as visual function (such as depth perception/stereopsis).

Doing nothing is also not a good option. A patient with strabismus has little to no depth perception which will affect their ability to judge depth and distances such as while driving a car or catching a ball. It will also diminish your reading skills because the brain must ignore or suppress the eye that is deviating to prevent from seeing double vision. This wastes energy and attention is drawn away from the task at hand. Also, when one visual pathway is not stimulated and developed, that side of the brain doesn’t develop, and amblyopia usually occurs where the eye is not correctable to 20/20 vision, even with glasses, contact lenses or LASIK.

Usually the best option is Vision Therapy if the amount of eye drift is small, or intermittent. A combination of surgery and Vision Therapy is best if the deviation is larger.

Is LASIK or refractive surgery right for me?

Monday, September 14th, 2009

I am often asked if LASIK or refractive surgery is right for a patient. The answer is, it depends on your eyes, and your lifestyle. Overall, LASIK is very safe. With today’s technology, there are very, very few post-surgical complications  so I can recommend it to my patients. I am very conservative in my treatment, and would only recommend a procedure to my patients that I would recommend to my own family.

That having been said, LASIK is still surgery, and we need to do a pre-operative exam to make sure that your eyes are healthy and suitable for LASIK.
Before you see the surgeon, we evaluate the following aspects of your eyes such as:
* Ultrasound to measure the thickness of your cornea for creation of the flap
* Tear analysis
* Cycloplegic refraction (prescription analysis under dilation)
* Topography (map of corneal surface)
* Pupil measurement
* Lifestyle analysis (to determine the target post surgical prescription goal i.e. monovision, under correction, full distance correction, etc.)

If everything looks good, you’ll meet the surgeon and schedule your procedure.

We will see you after surgery over the next several months to make sure that your eyes have healed properly.

LASIK or refractive surgery can be life changing for some patients as they wake up every morning seeing clearly. It is important to do it correctly, and choose the best surgeon after we’ve determined that your eyes are suited for LASIK.

Does My Child Need to Have an Eye Exam?

Thursday, July 23rd, 2009

This is the number one question that I receive from parents. The answer is YES, by 6 months old, and yearly thereafter. The reason is because 80% of the information taken in while reading and writing is through the visual system, so vision problems can interfere significantly with learning. Early vision problems can also delay development in areas such as eye hand and eye body coordination which affect walking, reaching, crawling, and balance for infants and toddlers.
The vision exam needs to evaluate more than the need for glasses and eye health. Developmental or Behavioral Optometrists, such as myself, evaluate for age-appropriate visual motor and visual perceptual skills that affect learning and sports. Visual motor skills that important to learning include eye tracking, teaming and focusing. Visual Perceptual skills include visual memory, visual sequential memory, visual closure, and visual motor integration.

I did a post-doctorate Fellowship in Developmental Optometry or Pediatric Optometry, and serve as a consultant to over 40 schools in Los Angeles. I evaluated my own son at 6 months old, and often play games with him to develop his visual motor and visual perceptual skills since vision is the dominant sense and extremely important to learning and sports.
