The World’s Most Famous Eyewear

There is perhaps nothing as iconic in today’s fashion world as the eyeglass or sunglass. Not only is eyewear a medical device needed by over half the population, it is the only medical device that not only allows us but encourages us to express our individualism. From Elton John to Jackie Onassis, from Buddy Holly to Johnny Depp, eyeglasses help us express ourselves in fun and often colorful ways. Here is an infographic highlighting some iconic eyewear from the last 100 years or so and even some a couple of hundred years in the future from our friends at Pop Chart Lab.

Shark’s Eyes

sharks_14183634

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.

Eye See Omega 3’s

Omega 3 fatty acids are important for eye health as they can decrease the risk of age-related macular degeneration and are also therapeutic for patients with dry eye syndrome. Where do we get Omega 3’s? For most of us, we find all the Omega 3 our body can use in fish and fish oil. Since summer is a great time for fresh fish, we thought it important to remind you to fill your summer (and your tummy) with lots of great fresh fish.

Want another way to get Omega 3’s? To get the same amount of Omega 3 that you would get form 1 fillet of salmon you would need to eat a dozen eggs. Omega 3 eggs are a great eye food however; they don’t replace fish in the diet. Eating 2 servings of wild salmon (Alaska) per week and 2 servings of other cold-water fish will provide your body with an omega-3 intake equivalent to 850 mg of DHA and EPA per day. By comparison one omega-3 egg contains approximately 125mg of DHA (omega-3 fatty acids). Although they are not a replacement for DHA and EPA in fish, eggs are a great source of other eye nutrients such as lutein, zeaxanthin, vitamin E and zinc.

Spare Your Sight!

It’s that time of year. Spring has spring and summer is just around the corner. This is the time of year everyone is outside and everyone is thinking sunscreen.

This can all be easily avoided by having a good pair of sunglasses close by. Our friends at The Vision Council have put together this infographic showing the dangers of spending time outside without quality sunglasses.

There Is No Pink

19391518_s1[1]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.

Eye Workout

eye-roll_65755899BOut 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!
