 A 40 year-old patient came to our office complaining of blurred vision in her left eye more than her right eye.  She had worn glasses in the past and her contact lenses were never clear out of her left eye.  She stated that her astigmatism was worse in her left eye than her right. Below are her test results using the Visionix VX-120 screening technology that is tested on every patient at our clinic.



Astigmatism occurs when the light that enters the eye is out of focus, causing blurred vision whether looking far away or up close.  It is a very common condition and seen daily at our office.  The cause of astigmatism is usually due to the front part of the eye called the cornea being more curved in one meridian than the other meridian.  Think of the eye as a clock that goes from 12 - 6 in one meridian and 3 - 9 in the other meridian.  One meridian is more curved than the other meridian resulting in astigmatism.  This results in the eye being more shaped like a “football” rather than a baseball, this is called regular astigmatism.  


Our patient has a condition called pellucid marginal degeneration which causes the bottom part of the front surface of the eye (cornea) to be thinner than the rest of the cornea resulting in irregular astigmatism. It is a slowly progressive disease that gets worse over many years.  This is the reason why her traditional astigmatism contact lenses never fit her well and were always uncomfortable. In the past, she was never screened for this condition and was glad she finally knew why her left eye was more blurry than her right eye.  Fortunately, there are options to correct her vision, one of the best options is a specialized contact lens called a scleral lens.  A scleral lens differs from a normal contact lens in that it can correct irregular astigmatism.  She was thrilled with this option and will return to our office for a custom contact lens fitting to improve her vision.

Myopia or nearsightedness occurs when light enters the eye and is focused in front of the retina, causing distance objects to be blurred. This disease has increased 40 percent in the last 30 years in the United States.  Eye doctors are diagnosing myopia at a younger age than in the past and an area of concern is high myopia (greater than -5.00 D). High myopia can lead to conditions such as cataracts, glaucoma, and retinal detachment.  

Risk factors for developing myopia

  • Family history
  • Time spent outdoors
  • Time spent on near work
  • Age of onset
  • Ethnicity

If one parent is nearsighted, a child is 40 percent likely to be nearsighted.  If both parents are nearsighted, the child is 70 percent likely to be nearsighted.  In addition, children that spend time more indoors are more likely to have progression in their myopia than children that spend more time outdoors.  The American Optometric Association recommends 12-14 hours of outdoor activity a week. Due to the increase use of digital devices, children are becoming more myopic as well.  It is recommended that young children spend no more than 1-2 hours on digital devices. I understand it is very difficult in this day in age to do that.  Parents must be proactive and understand that myopia is a disease that can cause impaired vision as it progresses.  

Traditionally, glasses have been prescribed to correct myopia.  More recently, numerous studies have been conducted on methods to reduce myopia progression.  One of the most effective methods is called Orthokeratology or Ortho-K. Ortho-K is a process of wearing rigid gas permeable contact lenses at night to reshape the front surface of the eye called the cornea.  The lenses are removed during the day and the child can see all day without wearing glasses or contact lenses. Think of this treatment as braces for your eyes instead of your teeth.  Studies show on average Ortho-K can reduce myopia progression by as much as 50 percent.  Ortho-K provides a distinct advantage over other types of vision correction including freedom from wearing daytime glasses and contact lenses and slowing the rate of myopia. View the video below to see how Ortho-K works.


Call our office today 925-743-1222 to schedule a consultation to see if your child is a candidate for Ortho-K.

Halloween is around the corner, it is time to get your costume ready!  Some of us may want to purchase decorative contact lenses to enhance our costume.  But where can we get these lenses? You may think that it is a good idea to purchase the contacts online, beauty salons, or other over the counter locations.  However, ill-fitting contact lenses can lead to eye infections, eye allergies, and potential for irreversible vision loss.  


All contact lenses are classified as medical devices by the U.S. Food and Drug Administration (FDA) and a require a valid prescription which includes the size and curvature of the contact lens.  It is important to have an eye examination and contact lens corneal health evaluation to determine if your cornea is healthy enough for contact lenses.  A corneal health assessment includes corneal topography which allows your eye doctor to determine the size and curvature on the front surface of the eye.  This allows your doctor to customize the fit of the contact lens on your eye with the proper prescription, size, and curvature.  Take a look at the decorative contact lenses below that we fit at our office:

Halloween Contacts 

The American Optometric Association (AOA) offers the following recommendations for all contact lens wearers:


  • Wear contact lenses only if they are fitted and prescribed by an optometrist.

  • Do not purchase contact lenses from gas stations, video stores, websites or any other place not authorized by law to dispense contact lenses.

  • Properly clean and disinfect your contact lenses as instructed by your eye-care professional.

  • Wash and thoroughly dry your hands before handling and cleaning your contact lenses.

  • Never swap or share contact lenses with anyone.

  • Never sleep while wearing contact lenses unless they are extended-wear lenses designed for that purpose.


At our office, we offer a large variety of decorative contact lenses that are non-prescription and prescription including astigmatism correction.  Call our office today to schedule a contact lens and corneal health evaluation to accent your halloween costume! Deadline to order is Oct 18th!

In recent years, contact lens technology has offered great comfort and vision throughout all hours of the day.  At our office, about 75% of our patients wear daily disposable lenses which are thrown out at the end of each day.  However, with the advancements in contact lens technology, some people believe they no longer need to wear glasses.   Here are some reasons why you need a current pair of prescription eye glasses.  


1) You need to rest your eyes

After a long day of contact lens wear, the eyes need to rest in order to get the oxygen needed to remain healthy.  It is good practice to remove your contacts after 12-16 hours of wear and switch to eyeglasses.  Try to do this at least every few hours every evening and one day during the week.  


2) Allergies

Allergies usually cause problems with your eyes during the different seasons.  This may force you to remove your contact lenses to get relief.  Allergy eye drops are prescribed to reduce symptoms of itchy, burning, and watery eyes. Glasses would be necessary to maintain comfortable vision until eye allergies have been reduced.  


3) Eye Infection or Trauma

We routinely see irritated eyes from infections and scratched corneas at our office.  Discontinuation of contact lenses is a must during these situations in order for proper healing.  Medicated eye drops are prescribed to treat infections and heal the eye. Up-to-date eye glasses become necessary during this situation.    


4) Other Events

There are other reasons why you may not be able to wear your contacts.  If you tear or rip a contact lens, if you run out of contact lenses, you will need to wear your glasses.  Parents of newborns and young children are awaken in the middle of the night and need to be able to see right away.  This is where eyeglasses become handy!  Also, if you have an new pair of glasses, you will be more likely to wear them.  Your old, thick, beat up pair of glasses may be preventing you from taking a needed break from your contact lenses.  Come to our office today to discuss your eyewear options with our optical team.  925-743-1222

Are you suffering from dry, irritated eyes at the end of the day? Are you using copious amounts of artificial tears to relieve these symptoms without improvement?  In this age of DIY, many people take it upon themselves to treat their dry eye.  It can’t possibly be that difficult right? My eyes are dry, I just need to put drops in  and they will get better.  If you have been to the eye section in your neighborhood pharmacy, there is an abundance of different eye drop formulations readily available. But which one to choose? Your eye doctor may have recommended an eye drop to use on a daily basis and tells you that he will see you next year.  You use the drops for about a week, maybe two.  Life goes on and you forget.  Meanwhile your dry eye symptoms remain.  

At our office we take dry eye seriously, it is a disease, it is chronic, and it can make you very uncomfortable.  That is why we have incorporated a Dry Eye Center of Excellence. We employ a technology called the TearLab, which measures the salt concentration of tears in the eyes.  A sample of tears is taken from each eye to determine the health and stability of tears.  The number that is measured is mild, moderate, or severe and can be compared overtime to determine if treatment is effective.

 Once we determine your osmolarity number using TearLab, we can design treatment tailored for your specific condition.  

In addition, we utilize a technology called the Keratograph 5M exam, which allows us to capture high resolution images of the surface of the eye. This allows us to measure the amount of tears on the eyes, the rate of evaporation of tears, and meibomian gland drop-out.  The meibomian glands are located in the upper and lower eyelids and are responsible for stabilizing the tears to prevent tear evaporation.  Often, these glands are not functioning properly leading to dry and irritated eyes.   Up to 80% of dry eyes are due meibomian gland dysfunction.

Once the data has been collected on your dry eyes, a tailored treatment regimen is prescribed.  Follow-ups are scheduled in one to three months to evaluate effectiveness of treatment.  Treatment can include warm compresses, specific over-the-counter eye drops, pharmaceutical eye drops, and in-office expression / debridement of meibomian glands. Measurements are taken again at follow-ups including osmolarity to see if the prescribed treatment is working.  We do not know if something is improving unless it can be measured and the dry eye evaluation allows us to do just that.
