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.

At our office, I participate in a program called InfantSEE, which allows for a one-time, no cost visual evaluation for children 6-months to 1 year of age.  Conditions such as farsightedness, nearsightedness, astigmatism and amblyopia or lazy eye can be uncovered during this vision assessment.  In addition, severe conditions such as retinoblastoma, a rare eye cancer that affects infants can be uncovered during an InfantSEE examination.  I examined an infant who had retinoblastoma last year.  He was referred to a specialist and is currently undergoing chemotherapy to save his eye. It is never too early to get your child’s eye examined.



Unless we take the time to look at the individual structures of the eye, it is unlikely that we can determine if the eyes are completely healthy.  In our office we incorporate technology to help us diagnose eye conditions early to prevent vision loss.  One of our instruments is called the Visionix. It measures six ocular modalities including the curvature on the surface of the cornea as well as measuring the thickness to rule out thinning conditions of the cornea.  The other instrument is the Optomap Retinal Exam, which allows us to take a picture of the back of the eye to rule out cancers and other ocular diseases.



Many young children cannot communicate their vision problems.  They may be able to see the board or read the bottom line at the pediatrician’s office, but can still have symptoms of eye strain and headaches.  This can lead to poor concentration and aversion to reading. This contributes to children being misdiagnosed as having dyslexia, ADD or ADHD.  A full visual assessment includes evaluating eye alignment, eye movement, eye tracking, and eye teaming to rule out a vision problem.  



Often, when children start to complain, there is already a significant prescription needed or an eye disease that is developing.  When we take this approach, we are being reactive instead of proactive.  Would you wait until you had a heart attack to find out you needed to take blood pressure medication? I hope not.  It would be responsible to check your blood pressure annually at your primary physician’s office including a complete blood work up.  Same goes with an eye examination.  It should be done at least annually to prevent vision loss.  A 12 year-old girl came to our office and complained of blurred vision.  Our eye examination uncovered a condition called keratoconus, a progressive thinning condition on the front surface of the eye that causes irregular astigmatism. She was referred for a surgical procedure called cross-linking to help strengthen the front surface of her eye to prevent further thinning.



We make time for vacations, going to the park, swim practice, baseball practice, band practice etc…We want the best for our children in their learning and development.  An eye examination takes about 1.5 hours from start to finish and there are 8,760 hours in a year.  You have the time and your children’s eyes cannot afford to wait.

Daily disposable contact lenses are single-use contacts that are discarded at the end of the day.  The next day, a new pair of lenses are worn.  Daily disposable contact lenses should not be confused with other disposable  contact lenses which can be worn bi-weekly, monthly, or quarterly depending on the brand.  

Why throw away your contact lenses?

Frequent replacement of contact lenses is healthier for the eye and leads to better overall comfort.  Protein and other substances found in your tears can build up on the lenses leading to uncomfortable contact lenses and increased risk for infection.  Non-daily disposable contact lenses are usually stored in a case and re-worn for a given time period.  Although cleaning is done, some deposits on the lenses still remain over time.

Benefits of Daily Disposable Contact Lenses

  1. No lens cleaning required
  2. No day to day accumulation of deposits
  3. Wide range of materials for better comfort and ocular health
  4. Available in colors, in designs to correct astigmatism, and in multifocal designs to correct presbyopia
  5. Affordable -about the price of a cup of Starbucks coffee.
  6. Great for patients that have eye allergies because lenses are disposed of at the end of the day along with the allergens.
  7. Part-time wearers - if you prefer to wear contact lenses for sports, on the weekends, or traveling. daily disposable contact lenses are a great option. It can be more convenient to travel with a pack of contacts instead of bottles of solution.

Schedule a contact lens evaluation today to determine if daily disposable or frequent replacement contact lenses are right for you.  925-743-1222.
