swimming edit2Taking proper care of your contact lenses is critical to staying free of eye infections. As part of a proper maintenance regimen, avoid exposing your contacts to water. That includes tap water, well water, showers, hot tubs, and any water you might swim in.
Contacts are like sponges, soaking up any chemicals or bacteria contained in the water they are exposed to. They can also trap bacteria between the lens and the surface of the eye.

One type of bacteria found in water (even chlorinated water) that can be a menace to eyes is Acanthamoeba. Acanthamoeba can cause painful corneal infection called Acanthamoeba keratitis. According to the Centers for Disease Control and Prevention, over 85 percent of cases involve contact lens wearers. Besides pain, symptoms include redness, blurred vision, light sensitivity, a burning/itching sensation, and excessive tearing. Acanthamoeba keratitis is sight threatening and may necessitate a corneal transplant if not diagnosed and treated promptly.

Never clean your contact lenses with tap water or homemade solutions, and never wear contacts while showering or swimming. If you absolutely need the vision correction that contacts provide while swimming, also wear a pair of airtight swimming goggles to create a barrier.

Changes in your eyes or vision warrant a call to our office. Don't take chances with your sight.

sunglasses on beachThere are plenty of misconceptions about sunglasses. We'd like to clear a few of them up.

MYTH #1: All sunglasses provide ultraviolet (UV) ray protection.

Truth is, some sunglasses are deficient or provide no UV protection at all. Make sure lenses are rated UV400 or higher, which block out 99.9 percent of UV light (UVA and UVB).


MYTH #2: The darker the lens, the more UV protection you have.

UV protection is determined by either a lens treatment or the type of plastic polymer of the lens. The degree of lens tint has no bearing on UV protection.


MYTH #3: As long as your lenses provide 100-percent UV protection, you're set.

Some sunglasses allow too much UV light to enter the eyes from the side, top, and/or bottom of the lenses. Wraparound sunglasses are a good solution.


MYTH #4: Sunglasses can “expire.”

Currently, there is no evidence that UV protection diminishes over time. An accumulation of scratches, however, can distort vision and cause eye strain.


MYTH #5: You don't need sunglasses on cloudy days or over the winter.

UV light can be just as intense (or more so) during these times. Wear your sunglasses anytime you're outdoors during daylight hours.

If you need a new pair of sunglasses, come check out the efficient and stylish selections we carry at our office.

eye closeup edit

A pinguecula is a yellowish bump that forms on the white of the eye (sclera), near the edge of the cornea. More often than not, it arises on the side nearest the nose.

Overexposure to ultraviolet (UV) rays is the primary cause of a pinguecula. Frequent exposure to dusty, windy, or extremely dry conditions can contribute as well. Those who are middle-aged or older are at highest risk.

A pinguecula is not cancerous, but any growth on the eye should prompt an optometric checkup. In many cases, a pinguecula is not bothersome; however, for some people it can be a nuisance and more:

  • If a pinguecula is big enough, it may cause difficulty in wearing contact lenses.
  • Since a pinguecula is a raised bump, the tear film may not spread evenly, leading to dry eyes (stinging, itching, foreign-body sensation, etc.).
  • A pinguecula may become swollen or inflamed (pingueculitis).
  • “Attractive” is not a word generally associated with a pinguecula.

Treatment varies depending upon symptoms and severity. Various eyedrops (prescription and/or nonprescription), nonsteroidal antiinflammatory medication, and scleral contacts may be beneficial. Some people want a pinguecula surgically removed due to functional or cosmetic reasons. Wearing UV-protective sunglasses whenever outdoors in daylight hours is an important piece of the puzzle, too.

Diabetes is a disease that interferes with the body’s ability to use and store sugar.  Too much sugar in the blood can cause damage throughout the body, including the eyes. Diabetic retinopathy is the result of damage to the tiny blood vessels that nourish the retina. It is the leading cause of blindness in the United States. According the the American Optometric Association, a third to half of the people with diabetes don’t receive annual eye exams.  In addition, 20-40 percent of individuals with type 2 diabetes have diabetic retinopathy at the time of diagnosis of diabetes.


Symptoms of diabetic retinopathy include

  • Seeing spots or floaters in your field of vision
  • Blurred vision
  • Having a dark or empty spot in the center of your vision
  • Difficulty seeing well at night

Often there are no visual symptoms in early stages of diabetic retinopathy.  That is why it is recommended that everyone with diabetes have a comprehensive eye exam once a year. Early detection and treatment is key to limit vision loss from diabetic retinopathy.


If you are diabetic, you can help prevent or slow the development of diabetic retinopathy by taking your prescribed medication, sticking to your diet, exercise regularly, controlling high blood pressure, and avoiding alcohol and smoking.  

childrens eye exam

August is here and with it comes the start of the new school year!  Time for new clothes and new stationary. Going to get an eye exam can be overlooked during this busy time.  The goal of Children’s Vision and Learning Month is to educate the public about the relationship between vision and learning.  


Common signs of learning-related vision problems

  • Headaches, eye strain
  • Short attention span
  • Excessive blinking or eye rubbing
  • Poor hand eye-coordination
  • Difficulty remembering what was read
  • Holding reading materials close to the face
  • Covering one eye


20/20 does not always mean normal vision

Many parents incorrectly assume when their child passes a school vision screening, there is no vision problem.  However, a child can have 20/20 vision but still have trouble seeing. 1 in 4 school age children suffer from an uncorrected vision problem. Up to 80 % of the learning children do is through their eyes, so having an undiagnosed and untreated vision problem can have a negative effect on their education, confidence, and ability to socialize.  The only way to be sure your child can see clearly is a comprehensive vision exam.

A comprehensive eye exam also includes color vision testing, eye tracking, eye movement, eye alignment,  and depth perception. In addition, the eye health portion of the exam includes evaluating the outer and inner ocular structures of the eyes.  With school starting soon, we want to make sure that your child has the best opportunity to learn and see the world clearly. Start the school year off right by scheduling a comprehensive eye examination for your child today at our office.  Call today 925-743-1222.
