Why You Should Stop Rubbing Your Eyes

Preserving healthy eyes in San Jose & Bay Area

Rubbing your eyes is a natural response to itches, irritation and allergies. Most of us have been doing it for a very long time — since infancy, in fact. Watch a baby wake up in the morning and you’re very likely to observe this hardwired behavior.

But as natural as it may be, and as logical as it may seem, routinely rubbing your eyes can have negative consequences, ranging from scratched corneas to keratoconus. Below, Bay Area ophthalmologist Mark Mandel, MD, discusses some of the risks.

Under Pressure

One of the main reasons that we rub our eyes is that it works. By rubbing the eyes, we stimulate tear flow, and this can wash away whatever is irritating the eye. It also has the unexpected effect of relaxing the vagus nerve, which can reduce stress.

Because the eye is so fragile, even a moderate amount of rubbing can result in damage. When rubbing causes small blood vessels to break, the eyes appear blood-shot. Leakage from capillaries can even help create dark circles under the eyes.

In the process of rubbing the eyes, your hand may transfer germs to the area, which can cause conjunctivitis or other infections. If there is dirt, debris or a grain of sand in the eye, it can scratch the cornea when you rub your eyes. The effect is even greater if you wear contact lenses.

Too much rubbing can affect your vision, changing your prescription by shortening or lengthening the distance between lens and retina. It can also cause an increase in intraocular eye pressure, which is especially dangerous for those already suffering from elevated eye pressure.

Constant eye rubbing can wear away the thickness of the cornea. When the cornea loses integrity, it may gradually become more conical in shape, resulting in keratoconus, a condition that can seriously impact the health of your eye and the clarity of your vision.

The Liquid Solution

The way to prevent all these effects — refraining from rubbing your eyes — is easier said than done. Eye rubbing is a natural response that we need to make a conscious effort to unlearn. The best alternative to addressing dryness and irritation is to wash the eye with sterile saline, eye drops or water. Flushing away dust and debris is the safest way to restore comfort and protect your delicate eyes.

Five Things That Are Better After LASIK

LASIK in San Jose & Bay Area

Life after LASIK is all about clarity, convenience and freedom. Below, trusted Bay Area ophthalmologist Mark Mandel, MD outlines a few of the many life-changing benefits of today’s advanced LASIK.

1. Clear Vision

By reshaping the cornea with a cool-to-the-touch surgical laser, an ophthalmological surgeon can ensure that images received by the eye are focused on the retina with maximum sharpness. The result is a high-definition view that features a whole new dimension in clarity.

2. Your “Prescription” Stays the Same

For most patients, LASIK is a once-and-done procedure that permanently corrects vision. That means no more annual adjustments to your prescription. This long-lasting benefit of LASIK is especially true for patients who undergo the procedure after their eyes have fully matured, which typically happens in their early to mid-20s.

3. Panoramic Views

After LASIK, your field of vision is wide open, without the visual intrusion of eyewear. You’ll enjoy the convenience and freedom of unlimited peripheral vision, unframed by frames.

4. Reading Is a Breeze

At age 40 or above, you are likely to experience presbyopia, the condition that makes it harder to read small print at close distances. If we perform monovision LASIK (one eye distance and one eye near), most patients achieve superb vision at distances near and far, meaning there’s no need to rely on reading glasses or bifocals when reading books and magazines.

5. Future Savings

Prescription lenses with frames typically cost hundreds of dollars. If your prescription changes frequently, or you simply have a habit of misplacing or cracking your glasses, the expense will be substantial.

Costs for contact lenses add up quickly, too. Depending on the recommended frequency of disposal, you will pay several hundreds of dollars each year for fresh lenses. Contacts that correct for astigmatism will be more expensive. During your regular eye exam, you will also pay extra for an additional contact lens fitting. LASIK eliminates all of these future expenses.

If you would like to know more about the benefits of LASIK, we encourage you to schedule a personal consultation with Bay Area ophthalmologist Mark Mandel, MD. Contact Optima Eye by emailing us or calling 877-210-2020 ext. 3 today.

What Is Life Like With Cataracts?

Cataract Surgery in San Jose & Bay Area

Patients who delay cataract surgery often find the world is a dull and hazy place. Images blur, colors fade and vision slowly dims. These effects have real consequences for the quality of life, and even the safety, of individuals whose cataracts have become advanced. Here, Bay Area ophthalmologist Mark Mandel, MD reviews some of the challenges presented by this limiting condition.

Overcast Vistas

Cataracts occur when the lens inside your eye becomes cloudy, obscuring the image it projects on the retina. This process can begin in our 50’s or 60s, and becomes more common with each passing year. The clouding effect progresses slowly, and its main recognizable symptom is the gradual blurring of vision.

In addition to overall deterioration in eyesight, cataracts lead to a decline in your ability to read fine print and reduce the clarity of your nighttime vision. Both can have profound effects. Those who suffer from cataracts often require much brighter light to read even medium-sized text. Without this higher wattage, reading puts additional strain on the eyes. And loss of sharp nighttime vision is a very dangerous thing for anyone driving after dark. Cataract sufferers will often experience nighttime vision anomalies such as glare, halos and starbursts around lights.

Cataracts can also make life less vivid, in a very literal sense. Colors seem dull and faded, and may take on a yellowish tint. The world around you begins to resemble a musty, sepia-toned photograph.

As the condition progresses, those experiencing cataracts may try to compensate by seeking stronger prescriptions for their glasses or contacts. This is only a partial fix that will not lift the fog in your field of vision. The problem is a clouded lens, not the way the lens focuses light on the retina. 

A Proven Surgical Remedy

The good news is that all of these burdens are completely unnecessary. The solution — cataract surgery — is convenient and routine. Millions of cataract surgeries are performed each year. In this procedure, the clouded lens is removed and replaced with a lens implant that will remain clear for life. Originally performed with the use of a miniature blade, cataract removal can now be done using a femtosecond laser to make incisions.

As a premier eye surgeon, Mark Mandel, MD performs advanced cataract surgical procedures for patients in the Bay Area and throughout Northern California. He also offers state-of-the-art intraocular lenses (IOL) that will replace your natural lens with a permanent, resilient artificial version that, depending on your choice, can give you superb vision at a variety of distances. These lenses can be adjusted for distance for each eye; near in one eye and distance in the other (monovision), or a multifocal lens can be implanted which allows good distance, intermediate (computer and dashboard) and near vision (phone and reading). Astigmatism implants can reduce or eliminate your astigmatism.

What Are Punctal Plugs?

Usually the first line of defense against dry eye disease is to identify common lifestyle or environmental factors that could be contributing to symptoms, and then systematically eliminate those factors. If you see Bay Area ophthalmologist and cornea specialist Mark Mandel, MD, for dry eye symptoms, he may recommend that you modify or eliminate medications known to cause dry eye, up your intake of omega-3 fatty acids and add moisture to the air in your home with a humidifier. He may also recommend using artificial tears or medicated eyedrops to increase the moisture on the surface of your eyes.

If these measures do not control your symptoms, he may recommend an alternative treatment, such as the placement of punctal plugs, to make your eyes more comfortable.

Elevated Eye Pressure: Causes and Concerns

Ocular hypertension treatment in San Jose

Regularly checking your eye pressure is an important way you can help preserve your vision for a lifetime. Elevated eye pressure can occur without symptoms, and is as dangerous to your eyes as high blood pressure is to your organs. It is often the first sign that you may be developing glaucoma, a leading cause of blindness.

Below, experienced Bay Area ophthalmologist Mark Mandel, MD, discusses prevention and treatment strategies for this serious condition.

Elevated Danger

The cause of elevated eye pressure, known as ocular hypertension, is an imbalance in production and drainage of aqueous humor, the fluid inside your eye. Pressure builds as the eye creates new fluid and the channels which normally drain the aqueous humor become obstructed or damaged. Once that happens, internal pressure rises, and major damage to the optic nerve can result.

In many cases, there is no observable damage to the release channels, yet the natural system of drainage unexpectedly stops working. This system can also be disrupted by an injury to the eye (e.g., a sports injury or car accident) that damages those vital drainage channels, setting in motion the increase in pressure.

Additional Causes of Ocular Hypertension

You are at greater risk for developing ocular hypertension is you are over 40, have thin corneas or a family history of glaucoma. African Americans also have a statistically higher risk.

Use of steroids, including steroid eye drops that are sometimes prescribed after eye surgery, is also linked to elevated pressure within the eye. In addition, ocular hypertension may suddenly appear with the onset of other eye conditions, such as pseudoexfoliation syndrome, a condition related to age and genetics in which small protein fibers accumulate, clump together and block the free flow of fluid within the eye.

Pigment dispersion syndrome can similarly cause accumulation of drainage-blocking particles in the eye. When this condition occurs, granules of pigment break loose from the iris and obstruct one or more channels.

If you would like to know more about elevated eye pressure and ways to protect your vision, we encourage you to schedule a personal consultation with Bay Area ophthalmologist Mark Mandel, MD. Contact Optima Eye by emailing us or calling 877-210-2020 ext. 3 today.
