Dry Eyes? Learn How LipiFlow® Can Bring Relief

Are you going through each day annoyed by the itchiness, stinging and redness of dry eyes, because nothing helps to soothe your sore vision? Revolutionary LipiFlow® can be your answer.

To discover how this dry eye therapy works, book a specialized Dry Eye exam with our Sunnyvale eye doctor. We’ll assess your condition to identify the cause. If it’s meibomian gland dysfunction, we’ll introduce you to the LipiFlow® Thermal Pulsation System.

How does LipiFlow® work?

The LipiFlow® system has been clinically shown to be effective at relieving blockage of the meibomian glands. By applying warm heat and gentle pulsing pressure, LipiFlow® helps the body to restore normal production of lubricating tear film oils. Whereas moisturizing eye drops only help temporarily, LipiFlow® gets to the root of the problem — bringing lasting relief. Many of our Sunnyvale eye care patients report that their dry eye symptoms disappeared after the first treatment.

What’s the LipiFlow® treatment process?

The actual treatment with LipiFlow® takes about 12 minutes per eye, and both eyes can receive treatment at the same time.

  1. First, numbing eye drops will be placed in each eye, and we’ll clean any debris from your lash lines and the edges of your eyelids.
  2. The LipiFlow® eye piece will be placed gently into each eye; you’ll need to keep your eyes closed lightly throughout the treatment.
  3. You will feel warmth and mild pressure on your eyelids. There are two six-minute cycles consisting of warming, pulsation and pressure. Together, these phases help loosen and eliminate any clogs in your glands.

LipiFlow® is virtually painless, and in most cases, maximum symptom relief occurs about two to four weeks after treatment – lasting for the next year and longer! A few weeks after your treatment, we’ll perform an evaluation to check the effects. LipiFlow® doesn’t just treat the symptoms, it solves the problem at the source.

Is Your Job Placing You at a Higher Risk For Dry Eye?

Dry Eyes? Learn How LipiFlow® Can Bring Relief

What’s Worse For Your Vision: High Myopia (Nearsightedness) or Smoking?


What Can You Expect from Myopia Control?

Myopia (AKA nearsightedness) is extremely common, with an estimated one out of every two people having it. It is caused when the shape of your eye is elongated, similar to a football shape, or when the cornea is curved too steeply. As a result of these irregularities, things in the distance appear blurry.

At our Sunnyvale eye clinic, we diagnose myopia regularly with an eye exam.

What’s Wrong with Regular Myopia Treatment?

Fortunately for the millions of adults and children who are nearsighted, myopia is usually corrected easily with glasses, contact lenses or sometimes, surgery. However, myopia, especially when it is progressive and leads to high vision prescriptions, can also increase your risks of future eye problems, such as glaucoma, cataracts and retinal detachment. So while eyeglasses can give nearsighted people sharp vision, the effects of this method of myopia treatment are limited. In contrast, myopia control can offer long-lasting benefits.

Introducing Myopia Control

Introducing myopia control – an approach that aims to slow the progression of myopia in children. While there is no way to totally prevent a child from becoming nearsighted, myopia management can stop it from getting worse. Subsequently, the child’s eye health as an adult can be protected.

Types of Myopia Management

There are various methods of myopia control, including some self-help measures that you can take:

  • Outdoor activity: Studies have linked too much screen time, on computers or any type of digital devices, to myopia progression. Encouraging children to spend more time playing outdoors may help slow the deterioration of nearsightedness.
  • Low-dose atropine eye drops: These drops may offer myopia control when given to children aged 5-18, in small doses for two to three years.
  • Multifocal contact lenses: Kids age 6-12 have shown positive results when wearing soft multifocals for myopia control. It’s believed that blurring side vision with these specialty contact lenses can slow eye growth and limit nearsightedness.
  • Orthokeratology: Ortho-k lenses are specialty contacts worn overnight to correct blurred vision during the daytime. They work by flattening the cornea as you sleep. Although ortho-k lenses only improve vision temporarily, it is believed that some permanent benefits on myopia progression may occur.

Benefits of Myopia Control

There are three primary long-term benefits of myopia management:

  1. Sharper, improved vision, because nearsighted adults and children have better visual performance when the degree of myopia is mild.
  2. Improved results from future surgical myopia correction, such as laser eye surgery, because the lower the myopia is – the fewer the surgical enhancements that are needed.
  3. Reduced risk of visual impairment from eye health problems in the future.

If your nearsighted child’s eye exams consistently lead to a stronger vision prescription, it’s time to look into myopia control. Contact our Sunnyvale optometry office to book a consultation.

When Does Dry Eye Disease Become a Problem?

It used to be dry eye disease (DED) was only regarded as a medical problem when the patient was female and over 40 years old. Other high risk populations included contact lens wearers and people taking specific medications. Not long ago, people who spend prolonged periods using a computer joined the list of those-at-risk of dry eye syndrome.

Now, we’re facing a whole new reality. In today’s world, almost everyone – from school-aged kids and up – has suffered from some degree of dry eye at some point. In fact, many people believe that red, irritated eyes are the normal, inevitable effects of computer use.

Dry Eye Can Be Prevented

It’s time to debunk the myth that dry eye is unavoidable. When a patient visits their eye doctor, the following issues should be discussed:

  • How many hours a day do you use digital devices?
  • How many monitors do you have? At what angle should monitors be positioned from the face?
  • How long does it take before you feel your contact lenses most days?
  • What medications do you take?
  • Do you have fans installed at home or near your desk at work?

Once the eye doctor better understands you and your lifestyle, the easier it is to intervene, prevent and treat dry eye symptoms. For example, eye doctors can advise you on optimizing the following:

  • Environment: You need an eye health and vision-friendly setting at home, school and work.
  • Diet: We are what we eat, and that includes the eyes! There are many vitamins that benefit the tear film and help prevent high-energy visible light from damaging delicate eye tissues.
  • Hygiene: Regular cleansing of eyelids and responsible makeup removal can help you avoid dry eye disease.
  • Eye exams: Everyone should visit an eye care provider yearly for comprehensive eye exams.

Dry eye disease can strike at any age. When left untreated, it can lead to even more serious problems in the future. Fortunately, there are plenty of ways to help prevent, treat and alleviate this painful condition.

Traumatic Brain Injuries Can Harm the Visual System — And Self Esteem

Does Your Child Have Myopia? Send Them Outside!

Tips to Relax Your Eyes

FOLLOW US: [socialicons size=”32px” shape=”square”

Traumatic Brain Injuries Can Harm the Visual System — And Self Esteem

Traumatic Brain Injuries Can Harm the Visual System And Self EsteemA traumatic brain injury (TBI) can harm vital communication between the brain and the visual system, bringing on disabling symptoms. People trying to deal with these symptoms may experience depression, anxiety, and low self-esteem.

They may no longer be able to perform tasks as they once did. After a concussion or more severe TBI, one may experience recurring headaches that necessitate frequent breaks while working or studying, reducing productivity. Or chronic dizziness from a blow to the head could prevent a person from driving, making them dependent on others. A child who’s suffered a TBI may be unable to participate in group sports or activities, making them feel “alone” or “different.”

That’s where we come in. If you or a loved one has suffered even a mild TBI, speak with Dr. Jesley Johnson about having your visual system assessed during a functional vision evaluation to determine if something can be done to ease your symptoms.

Signs of Emotional Distress Following a TBI

The struggle to read a book or catch a ball due to double vision or eye tracking problems can be demoralizing. A post-TBI patient could experience lowered self-esteem or depression. Be alert for these signs:

  • Social withdrawal
  • Persistent feelings of sadness
  • Lack of interest in personal hygiene or appearance
  • Negative self-talk
  • Lack of motivation
  • Being irritable or moody
  • Reduced or lack of appetite

How a Neuro-Optometrist Can Help

It can be discouraging to hear from other health professionals that there’s nothing to be done for lingering TBI symptoms. Fortunately, neuro-optometrists can help post-TBI patients in ways that few other health care providers can.

Neuro-optometry deals with the visual system and how it impacts daily functioning. By training the brain to more effectively communicate and control the eyes, symptoms like dizziness, headache, and nausea can be significantly reduced or disappear altogether.

Eradicating these debilitating symptoms can be life-changing and allow you to go back to doing what you love. Children may once again be able to play with their friends on the soccer field or basketball court. Adults may become more interested in socializing and exercising, and become more productive at work. Resuming these activities can boost self-esteem and feelings of self-worth.

At The Vision Therapy Center at Silicon Valley Eye Physicians, we know all too well the challenges that accompany a traumatic brain injury and how it can affect self-esteem. To schedule a functional visual evaluation and determine if a problem with the visual system is contributing to your post-TBI symptoms, call The Vision Therapy Center at Silicon Valley Eye Physicians today.

The Vision Therapy Center at Silicon Valley Eye Physicians serves patients from Sunnyvale, Santa Clara, Mountain View, Cupertino, and throughout California.



Can At-Home Learning Cause Vision Problems in Children?

Home LearningMillions of schoolchildren are studying at home in coronavirus-dictated on-line classes. While squinting at the blackboard is less common for now, remote learning presents students with other vision challenges. The most common problem is digital eye strain — also called computer vision syndrome. Spending many hours indoors has also been linked to the rapid progression of myopia, the elongation of the eye that causes nearsightedness.

These problems are especially worrying because children are spending an estimated 50% more time on-line compared to the days before the coronavirus.

Digital eye strain results from the prolonged use of digital screens. The eye strain then causes headaches, blurriness, dry eyes, difficulties with concentration, and neck and shoulder pain. The effects of digital eye strain are also worsened by any existing eye conditions — such as astigmatism, uncorrected anisometropia, and uncorrected eye movement problems.

It’s important that your children undergo a thorough eye exam, and to correct or treat eye conditions that can interfere with their learning, both in the classroom and online.

How Parents Can Help

Conditions that contribute to a child experiencing digital eye strain also include insufficient contrast between characters appearing on the screen and the screen’s background, the amount of glare emitted by the computer or tablet screen, being too close to or too far from the screen, and poor posture.

By monitoring your children’s learning environment and recognizing the signs of digital eye strain, you can prevent or at least minimize the effects of eye strain on your child. The American Optometric Association recommends:

  • Adjusting the device so that the center of the screen is approximately 5 inches below the eyes and 20–28 inches away
  • Tilting the screen to eliminate glare
  • Employing proper posture, with feet planted firmly on the floor, back straight, and wrists off the keyboard
  • Blinking frequently to keep the eyes moist
  • Taking frequent breaks away from the device (at least every 20 minutes)
  • Shutting devices at least one hour before going to sleep

Research has shown that children who spend significant time playing in the sunshine experience slower myopia progression than children who stay indoors. So make sure your children get plenty of sunshine, weather permitting.



If your children haven’t yet undergone their annual comprehensive start-of-school eye exam, schedule an appointment with Dr. Jesley Johnson. We’ll advise you and your children on how to keep their vision clear and comfortable and their eyes healthy during this extended period of at-home learning. The Vision Therapy Center at Silicon Valley Eye Physicians helps parents and children from Sunnyvale, Santa Clara, Mountain View, Cupertino, and throughout California.



How Can My Child’s Myopia Be Corrected?

At Silicon Valley Eye Physicians, we help children like yours achieve clear and comfortable vision, so they can succeed at the important things in life.

Methods of Myopia Correction

Contact Lenses

Contacts can be a great choice, especially for physically active children or teens who don’t want to worry about breaking or misplacing their eyeglasses. In some cases of very high myopia, contact lenses can offer clearer vision than glasses.

Corrective contact lenses are usually placed in the eyes upon waking and removed at night before bedtime. There are several types, including: soft contacts, daily disposables, extended wear, and rigid gas permeable (hard) lenses. Navigating through the differences between them can be daunting. Fortunately, if you’re located in Sunnyvale our eye doctor will be happy to guide you. Speak with Dr. David Mark to determine whether your child is ready for contact lenses.

Prescription Glasses

Glasses are a popular choice among our younger patients. Choosing from an array of styles makes the process fun and exciting! Allowing the children to be active participants in selecting their eyewear increases the likelihood that they’ll actually wear them. There are strong, flexible and resilient frames which look great and are comfortable too.

The optician can customize the lenses with additions and upgrades like impact-resistant or shatter-proof materials, scratch-resistant and anti-reflective coatings, UV filters, and transition lenses that darken in the sun. For those requiring vision correction for distance and near, we also offer bifocal or multifocal lens prescriptions.

We Can Help Correct Your Child’s Myopia

If you’re located near Sunnyvale, California, an eye exam with our optometrist can determine your child’s exact prescription, and give you the opportunity to receive answers to any questions you may have about your child’s eye health and vision. Progressive myopia, where a growing child’s prescription continues to worsen, is why it’s important for myopic children to undergo eye exams at least once a year.

At Silicon Valley Eye Physicians, our friendly and knowledgeable staff will be happy to recommend the most suitable method of correcting your child’s myopia to meet his or her individual needs. Thanks to the wide range options available, your child will walk away with eyewear that will not only enhance his or her style but will also be a boost of confidence.

Let us help your child see the world in a whole new light. To schedule your child’s annual eye exam or if you have any further questions, contact Silicon Valley Eye Physicians at 408-739-6200 today.

Are Floaters and Flashes Dangerous?

You’ve likely experienced occasional visual “floaters” or flashes and may have wondered what they were and if they’re a cause for concern. They look like tiny lines, shapes, shadows, or specks that appear to be drifting in the visual field. More often than not, seeing floaters is a normal occurrence and does not indicate a problem with ocular or visual health. However, when floaters become more frequent and are accompanied by flashes of light, that can indicate a more serious problem.

Eye flashes resemble star-like specks or strands of light that either flash or flicker in one’s field of vision. They can either be a single burst in one visual zone, or can be several flashes throughout a wider area. Flashes can sometimes be missed as they most often appear in the side or peripheral vision.

Floaters & Flashes Eye Care in Sunnyvale, California

If you suddenly, or with increasing frequency, experience flashes or floaters, call Silicon Valley Eye Physicians and schedule an eye exam with Dr. David Mark right away to rule out any serious eye conditions.

What Causes Floaters?

The vitreous in the eye is a clear gel that fills most of the eyeball and resembles raw egg-white. Within the vitreous are small lumps of protein that drift around and move with the motion of your eyes. When these tiny lumps of protein cast shadows on the retina — the light-sensitive lining at the back of the eye — the shadows appear as floaters.

As we age, the vitreous shrinks, creating more strands of protein. This is why the appearance of floaters may increase with time. Floaters tend to be more prevalent in nearsighted people and diabetics, and occur more frequently following cataract surgery or an eye injury.

If seeing floaters becomes bothersome, try moving your eyes up and down or side to side to gently relocate the floaters away from your visual field.

What Causes Flashes?

Flashes result from the retinal nerve cells being moved or tugged on. As the vitreous shrinks over time, it can tug at the retina, causing you to “see stars” or bursts of light. The process of the vitreous separating from the retina is called “posterior vitreous detachment” (PVD) and usually isn’t dangerous.

In about 16% of cases, PVD causes tiny tears in the retina that can lead to retinal detachment — a sight-threatening condition that causes irreversible blindness if left untreated.

Other possible causes of flashes are eye trauma or migraine headaches.

When To Call Your Optometrist About Floaters

If you experience any of the following symptoms, promptly make an appointment with an eye doctor near you for emergency eye care.

Symptoms You Shouldn’t Ignore

  • A sudden onset of floaters accompanied by flashes (which can be any shape or size)
  • An increase of floaters accompanied by a darkening of one side of the visual field
  • Shadows in the peripheral vision
  • Any time flashes are seen

In many cases, seeing floaters is no cause for concern; however the above symptoms could indicate retinal detachment—which, if left untreated, could cause a permanent loss of sight or even blindness.

If the receptionists pick up the phone and hear the main concern is floaters or flashes, they will try to squeeze in the appointment within 24 hours. Expect the pupils to be dilated during your eye exam, so the eye doctor can get a really good look at the peripheral retina to diagnose or rule out a retinal tear or other serious condition, as opposed to a non-vision-threatening condition such as uncomplicated posterior vitreous detachment (quite common) or ocular migraine.

Please contact Silicon Valley Eye Physicians in Sunnyvale at 408-739-6200 with any further questions, or to schedule an eye doctor’s appointment.

Warm Compresses Can Relieve Dry Eye

protect your eyes 640x350What Is Dry Eye?

Our tears are made up of water and oil layers. Dry eye (also known as dry eye syndrome) occurs when the eyelids’ meibomian glands do not secrete enough natural oil into the tears. This causes the eyes to become dry, itchy, red, and painful. Environmental conditions like dry or windy air, and staring at a screen or book for a long time, can also dry out your eyes.

Here’s What To Do About It

One of the best ways to make dry, irritated eyes feel refreshed is with a warm compress. A warm compress will open the oil glands and soften oil blockages, allowing oil to flow into the tears. Wet a clean washcloth or place it in a microwave for 20 seconds. Touch it to your wrist to make sure it’s not too hot, then place the compress on your closed eyelids for a few minutes while tilting your head back or reclining. When the compress cools, reheat and repeat.

Compresses slow the evaporation of tears. Their warm moisture provides relief by stabilizing the eyes’ tear film and improving the meibomian glands’ production of oil. With your eyes now hydrated and lubricated, they can also expel bacteria more efficiently.

Certain prescription eye drops also address dry eye, and steroids can provide relief. Others provide additional lubrication. Please consult with Dr. David Mark, Dr. Moshe Mendelson, Dr. Jesley Johnson, Dr. Jackson Lau and Dr. Kevin Wu, who can recommend or prescribe the best drops for your eyes.

Other home remedies include:

  • An air filter to eliminate irritants
  • A humidifier to increase moisture in the air and decrease evaporation of your tears
  • Drinking water to stay hydrated
  • Wearing sunglasses to deflect ultraviolet rays and wind that dry the eyes

Please Keep the Following in Mind:

  • Don’t make the compresses or washcloths too hot.
  • Use a different compress for each eye to prevent spreading an infection between the eyes.
  • We recommend lightly cleaning with a swab or cloth, then wetting and wiping your eyelids several times each day. Doing so can prevent bacteria from entering your eyes.

If you are experiencing dry eye, please bring it to our attention. Untreated, dry eye can sometimes cause corneal abrasions or ulcers, inflammation, and even vision impairment.



At The Dry Eye Center at Silicon Valley Eye Physicians, Dr. David Mark, Dr. Moshe Mendelson, Dr. Jesley Johnson, Dr. Jackson Lau and Dr. Kevin Wu will treat patients with dry eye from Sunnyvale, Santa Clara, Mountain View, Cupertino, and throughout California.



Tips to Relax Your Eyes

Do your eyes hurt after spending a significant amount of time reading, playing video games, driving, or staring at a screen? These visually intense activities can sometimes be hard on the eyes, causing uncomfortable symptoms like headaches and blurry vision. Other symptoms of eye strain can include light sensitivity, neck and shoulder pain, trouble concentrating, and burning or itchy eyes.

Fortunately, preventing painful computer vision syndrome and eye fatigue symptoms can be as simple as trying a few of these eye exercises. To learn more about digital eye strain and discover the best relief options for you, call Silicon Valley Eye Physicians at 408-739-6200 and schedule an eye exam with Dr. David Mark.

Relax Your Eyes with These Supportive Techniques

Many of these exercises are designed for computer users. Eye strain resulting from long drives, reading, or other activities, can be alleviated by modifying some of these recommendations.

The Clock Exercise

The clock exercise relieves strain on overworked eye muscles and can help you avoid headaches and eye pain, among other symptoms. Begin the exercise by imagining a large analog clock a few feet in front of you. Keep your head still and move your eyes to the imaginary 9, then to the imaginary 3.

Keep moving your eyes to the opposite pairs on the clock — 10/4, 11/5, 12/6, and so on. Hold your gaze for a second or two on each number before moving on to the next one. Continue doing this for 4-5 minutes.

The 20-20-20 Rule

The 20-20-20 rule helps you avoid dry eyes and eye strain by giving your eyes frequent breaks. After about 20 minutes of screen time or doing close-up work, focus on an object at least 20 feet away for 20 seconds. This gives the eyes a much needed rest and helps them relax. There are also free apps available that provide pop-up reminders that notify you when it’s time to shift your gaze.

Screen Ergonomics

The American Optometric Association recommends placing computer monitors 20 to 28 inches, or 50-70 cm, away from your eyes and the top of the computer should be at eye level or right below for optimum eye comfort. Glare filters can reduce the amount of glare produced by digital devices and improve your viewing experience.

Poor sitting posture can also contribute to eye strain. Your chair should be situated so that your feet are flat on the floor, or use an angled footrest for additional comfort.

Optimize your Eyewear

Since regular prescription lenses or glasses may not adequately meet your visual needs for lengthy computer use, you may benefit from wearing computer glasses. These prescription glasses are customized to your needs and also reduce glare and block blue light.


You don’t have to live with the discomforts of eye strain. If symptoms persist, it may be time to visit Silicon Valley Eye Physicians and get the relief you seek. Call our office to schedule a convenient eye doctor’s appointment.


When All Other Contacts Have Failed, Scleral Lenses May Be the Answer

Girl Beach Contact Lenses

Sclerals vs. Standard Lenses

Standard contact lenses — be they soft, rigid gas permeable, or disposable — are the most popular choice for people with refractive errors who don’t want to wear glasses. But because standard lenses rest directly on the cornea, they aren’t a good fit for people with very dry eyes or irregularly shaped corneas.

Patients who have an irregular cornea find scleral lenses to be ideal. They have a larger diameter than standard lenses that allows them to vault over the cornea and rest on the sclera (the white part of the eye). Because they form a dome over the cornea, scleral lenses protect it from scratches and abrasions.

Scleral lenses also store saline solution between the back of the lens and the front of the cornea. As a result, the eye’s surface stays lubricated, maximizing comfort. Vision remains reliable, too.

Because scleral lenses are larger than standard lenses and custom-fitted to the eye, they are more stable and less likely to pop out. Scleral lenses correct astigmatism even in people with highly irregular corneal surfaces.

Sclerals are often prescribed for patients who suffer from dry eye or other complications following LASIK or other corneal surgeries.

Because scleral lenses are custom made and comfort is paramount, they might require several visits to get the fit just right. To learn if you have a corneal condition that requires scleral lenses, visit The Scleral Lens and Keratoconus Center at Silicon Valley Eye Physicians. We help patients from Sunnyvale, Santa Clara, Mountain View, Cupertino, and throughout California.
