The Fourth of July is this coming Monday and with it comes the fun of fireworks. As our mother’s use to lecture us, it’s all fun and games until someone loses an eye. There are over 2,000 fireworks-related eye injuries that happen every year. Eye injuries include ocular burns, lacerations, abrasions, retinal detachments, optic nerve damage, and even ruptured eyes. At best these types of injuries are very painful, but at worst, they can be permanently and irreversibly debilitating. We want to remind all of San Jose to be careful this 4th of July.
- Attend only authorized public fireworks displays conducted by licensed operators.
- If you are a spectator, stay at a safe distance and wear eye protection. A significant percentage of injuries related to the eyes actually happen to bystanders.
- Adults handling fireworks should always wear safety goggles.
- Never hold a firework while lighting it, never stand over a firework while lighting it, and never approach a firework that you thought was lit but that didn’t go off. Douse all of these “duds” with water before approaching them!
- Never let children light fireworks, including sparklers. Sparklers can heat up to 1800 degrees Fahrenheit.
- Keep unlit fireworks and lighting devices away from other fireworks, and never store fireworks.
If for some reason you are injured on the 4th of July, seek medical assistance immediately! Meanwhile, do not rub your eyes, do not apply pressure to injured eyes, do not rinse injured eyes or apply any type of ointment, and do not remove objects stuck into your eyes. Also do not take any blood-thinning pain medications such as ibuprofen or aspirin.
Have a wonderful 4th of July weekend and we look forward to seeing you soon! Here is a list of fireworks shows in the Bay Area in case you haven’t made up your mind where you want spend your Monday at sunset.
It’s Shark Week! We are excited for the week-long celebration of Sharks on the Discovery Chanel. We thought it might be fun to share a little information on how sharks see their world while we all watch them.
Unlike human’s shark’s eyes are almost on completely different sides of their head, giving them an almost 360-degree view of their world. A shark does have a couple of major blind spots, one of which is directly in front of their snout and the other right behind their head, Like humans though, we sometimes wonder if mother sharks have proverbial eyes in the back of their heads.
Sharks can actually only see about 50 feet ahead which is why their sense of smell is so evolved. Remember, sharks can often smell a drop of blood as far as a quarter mile away. A shark’s eye has tapetum lucidum, which are mirrored crystals located behind the retina that help it see in the dark. Like a cat, it makes it appear that their eyes actually glow in the dark. Because of the tapetum lucidum, a shark can see about 10 times better than a human can in dim light.
Here is a fun fact we bet you didn’t know. You remember that pink blouse or shirt you own? Or perhaps the pink flamingos you see in a neighbor’s yard? Or the pink flowers you get every year for St Valentine’s Day? Pink is a great color, isn’t it? The problem is, pink doesn’t really exist. Pink as a singer is pretty darn good though. The primary colors we all see (ok…some of us are colorblind) is red, green, and blue. Every color we see is a combination of those three light colors.
In the design world we talk of additive colors and subtractive colors. In the additive world, when we add every color of light together, we get white. When we subtract every color, we get night, or black. If you think back hard enough, you probably remember some of your science classes back in high school or college in which you recreated Newton’s experiments of splitting light into colors with a prism. If you going to try it again, you will notice that the spectrum goes from red on one side, turning to yellow, then green, then blue, then violet….but no pink. Pink does not exist as a wavelength, but is instead a combination of red and blue, which are at opposite ends of the spectrum.
So what is pink? The simplest explanation is to call pink another name, minus green. Pink is white light, minus green. So next time you go shopping for a great shirt or blouse, be sure to ask what’s new in the minus green department and share this little bit of trivia with your friends and family.
Out of all my body parts, I feel like my eyes are in the best shape. I must do at least a thousand eye rolls a day!
Now that spring is here, did you know the most active muscle group in your body are your eye muscles? The external muscles that move the eyes are the strongest muscles in the human body for the job that they have to do. They are 100 times powerful than they need to be. The eye muscle is the fastest reacting muscle of the whole body, contracting in less than 1/100th of a second. In fact, the eye muscles work together to carry out no less than seven coordinated movements and allow the eye to track many different kinds of moving object.
If your eye muscles or your eyes in general, don’t seem in shape and ready for spring, schedule an eye exam with our very own Dr. Lucy Yen and let’s get you ready for summer!
You probably know that the eye is approximately the size of a ping pong ball, but did you know that it also contains over two million working parts? It’s a good idea to get your eyes checked regularly and thoroughly by our own Dr. Lucy Yen to keep all those working parts in good order.

Despite over 50 years of being told how bad cigarettes are for us and the mountains of scientific evidence that link smoking to lung cancer and heart disease, close to 60 million Americans still smoke cigarettes regularly. Smoking however, is bad for more than your heart, your lungs, and your wallet. Smoking is bad for your eyes as well. If you value your eyesight and we believe you do, our friends at All About Vision have put together this infographic sharing how cigarettes can harm your vision and even contribute to blindness. Guess there is something to that old Jerome Kerns song, Smoke Gets in Your Eyes.
Eyeglasses are more than just a helpful tool to help you see clearly. Designer glasses can also be a fashionable accessory that conveys your individuality and unique sense of style. Looking back over the last 50 years, eyewear has come a long way. At one point, thick glasses frames were considered strictly utilitarian, while we now view these Buddy Holly-like glasses as an iconic piece of fashion history. As time has passed, designer eyewear has changed and evolved, but there are certain styles that have made a resurgence and others that have stood the test of time. Explore this infographic from Eye Luv Lucy in San Jose to see what styles of glasses defined the last few decades.
