 On Monday, August 21st, 2017 a solar eclipse will be seen across North America.  The moon will cover at least part of the sun for 2 - 3 hours.  Halfway through the event, anyone within a roughly 70-mile wide path from Oregon to South Carolina will experience a brief total eclipse lasting about 2 minutes and 40 seconds, turning day into night.  

Since the bay area is about 500 miles away from Oregon,  we will see at most about 75 percent of the sun covered.  This will occur at 10:15 a.m. and last about 2 minutes.  

Here are tips on how to watch the eclipse safely

Always inspect your solar filter before use.  If it is punctured, scratched, or torn, discard it.

Use approved solar eclipse viewers.  The viewers need to meet international standard ISO 12312-2 for safe viewing. Sunglasses, smoked glasses, unfiltered telescopes or magnifiers, and polarizing filters are UNSAFE.

Before looking at the sun, cover your eyes with the eclipse viewers while standing still.  Glance at the sun, turn away and remove your filter.  Do not remove the filter while looking at the sun.

Do not look at the sun through a camera, telescope, binoculars or ANY other optical device while using your eclipse glasses; the concentrated solar rays could damage the filter and enter your eyes causing serious injury.

Always supervise children using solar filters.

Visit your doctor of optometry should you experience discomfort or vision problems following the eclipse.  If you have any questions please call us at 925-743-1222 for more information.

Overexposure to UV light can lead to ocular conditions such as photokeratitis, cataracts, pterygium, and macular degeneration.  

Photokeratitis - a sunburn of the eye causing severe pain.  The condition is also known as “snow blindness.”  Up to 80% of UV rays are reflected by the snow and the danger also occurs near swimming pools and the beach.  

Cataracts - the most common cause of reversible vision loss in people age 50 and older.  The UV rays cause clouding of the natural lens located in the eye by disrupting the arrangement of the fibers of the lens.  The World Health Organization (WHO) estimates that up to 20 percent of all cataract cases are attributed to UV radiation and are preventable.  

Pterygium - sometimes called “surfer’s eye” is an abnormal but benign growth on the surface of the eye starting in the corner near the nose and extending to the front of the eye (cornea).  Pterygium is linked to excessive exposure to the sun, wind or sand.  Childhood UV exposure increases the risk of pterygium.  

Macular degeneration - Leading cause of blindness in people 60 years of age or older.  Studies suggest that exposure to UV early in life, rather than in later years, is a strong predictive factor for developing macular degeneration.  The macula is the tissue behind the eye that located in the center of the retina to provide clear central vision.  Damage to the macula causes blurred detailed vision and dull colors in the center field of vision.  

UV Spectrum 2
The sun emits three kinds of radiation: UVA, UVB, and UVC. UVC gets absorbed by most of the Earth’s atmosphere.  UVB radiation is only partially blocked and burns the skin and the eyes causing sunburns and even skin cancer.  UVA  is not filtered and can cause the most damage to vision.  90% of U.S. adults are concerned about the health effects of eye exposure to UV, but many remain uncommitted to sunglass use.

How do I select the right pair of sunglasses?

Buy from a reputable dealer, such as a store or your eye doctor’s office.  Unlike shades purchased from thrift stores or street vendors, sunglasses sold at trusted retailers meet frame and lens safety criteria set by industry standards. You can use your vision plan to purchase prescription sunglasses and some plans allow for sunglass coverage after LASIK surgery.

Make sure 100% of UVA/UVB are blocked.  Look for the label on the sunglass lenses.

Think about your activities.  Someone who plays sports or cycles may want to use a different pair of sunglasses during their daily activities for both comfort and safety.  

Select a lens color that improves clarity and reduces glare.  Different colors and tints works in different ways depending upon the activity.  Talk to one of our opticians for more details. Watch the video below on how polarized sunglasses work.


 back to school

 By Michael Duong, O.D., F.A.A.O

School is starting up again soon, now is the time to schedule an eye examination for your child.

Problems such as nearsightedness, farsightedness, and astigmatism can cause difficulty with learning in the classroom.  It you cannot see, then you cannot learn.  The visual skills necessary for learning include eye movement, eye teaming, eye focusing, eye alignment, and visual perception ( the ability to process what the eyes see).  Many students may be unaware of problems with their eyes or may not be able to verbalize their eye problems.  Parents should look for common symptoms including:


  • Short attention span
  • Unable to finish school work
  • Poor reading comprehension
  • Tendency to cover one eye
  • Frequent blinking or eye rubbing
  • Frequent headaches

Many of the symptoms above can be misdiagnosed for ADHD or dyslexia when in fact the child has a vision problem.  80 percent of what we learn is through our eyes.  Having an undiagnosed vision problem can have a negative effect on learning, social situations, and confidence.  

Good Vision is not just 20/20

The school screening done at the school can measure how a child see’s at a distance but does not evaluate the visual skills necessary for learning.  Measuring how well a child can see 20/20 is just one component of a complete eye examination.  A comprehensive eye exam also includes color vision testing, eye tracking, eye movement, eye alignment,  and depth perception.  In addition, the eye health portion exam includes evaluating the outer and inner 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.

Diabetic Retinopathy

by Michael Duong, O.D., F.A.A.O

Diabetic eye disease is a group of disorders that affects people with diabetes.  Diabetes, if left untreated can cause blindness.  It is the leading cause of blindness in adults in the United States. Uncontrolled diabetes can lead to the following ocular conditions: diabetic retinopathy, diabetic macular edema (dme) , cataracts, and glaucoma.  

Diabetic retinopathy - high blood sugar causes the retinal blood vessels in the back of the eye to leak out.  This can lead to blurred and distorted vision.

Diabetic macular edema (DME) - is a consequence of diabetic retinopathy which causes the central area of the retina called the macula to swell and leak.  

Cataracts - a clouding of the lens inside the eye.  Usually affects older people, but those with diabetes are affected much younger.  Adults with diabetes are 2-5 times more likely to develop cataract than those without diabetes.  

Glaucoma - a disease that causes damage to the cable that connects the eye to the brain called the optic nerve.  In adults with diabetes, the risk of glaucoma nearly doubles.  

Early detection is key to preventing vision loss in patients with diabetes.  Make sure to see a primary care doctor annually to test your blood sugar along with cholesterol and blood pressure.  Stay away from foods that are high in sugar and saturated fats.  Diabetic eye disease can go unnoticed until vision loss occurs.  Patients with diabetes should undergo a comprehensive eye examination at least once a year.  

Contact our office at 925-743-1222 today to schedule your comprehensive eye examination if you have diabetes or borderline diabetic.  Please watch the video below for an overview of diabetes.

Due to the increase use of electronics, there is increased exposure to harmful blue light from these devices. Computer monitors, laptops, tablets, smart phones, LED TVs and compact fluorescent bulbs emit blue light.  Lets face it, we are not going to be giving up our digital devices anytime soon.  In addition, cumulative exposure to blue light can suppress melatonin and disrupt the natural sleep cycle.  

Blue light diagram 


Blue light over-exposure symptoms


  • Eye strain

  • Headaches

  • Blurred vision

  • Macular damage


Is your child at risk?


Ave Daily Digital device use


Children and Teens tend to hold digital devices closer and their larger pupils let in more of the harmful blue light. Studies show this may put them at higher risk for developing sleep disorders, behavioral problems, obesity, and vision loss.    


What can be done?
