Hurray! School is out for summer and that means more fun in the sun! Days spent building sand castles on the beach, playing at the park, and exploring outdoors can lead to prolonged sun exposure. Since kids have no problem playing outside from sunrise to sunset, it is especially important to have proper protection from the suns harmful rays. Learn how UV radiation affects your child’s eyes and how to keep their eyes safe!
Now that spring has sprung and patio season has begun, sunglasses have become an everyday essential once again. With all the products and information out there, it’s important to know what’s what. With our Sunglasses Edit, we hope to answer any and all of your questions about sunglasses. If you have any sunglass inquiries or questions, please contact us on Instagram, Facebook, or via email.
Over the years, we have become increasingly aware of how harmful UVA and UVB rays can be to our skin, but what about our eyes?
UVA and UVB radiation can be especially harmful to your eyes and the skin surrounding them. Excessive exposure can lead to a higher risk of eye diseases (such as cataracts, macular degeneration, and snow blindness), increase the risk of skin cancer, and accelerate aging (yes, wrinkles ladies and gentlemen).
So what can we do to defend against harmful radiation and keep our eyes happy and healthy? (And look fabulous, obviously)
Researchers at Caltech looked to nature for inspiration to design effective, longer-lasting eye implants.
Hyuck Choo, assistant professor of electrical engineering in the Division of Engineering and Applied Science at Caltech, has been working on designing an implant that measure intra-optical pressure in glaucoma patients.
The tiny implant flexes as eye pressure changes, and this change can be measured using a handheld reader. The problem he ran into was that to get accurate measurements the reader must be held at exactly a 90 degree angle with respect to the implant.
The Glasswing Butterfly’s wings are coated in tiny pillars, about 150 nanometers apart and 100 nanometer in diameter. These pillars redirect light from any angle, greatly reducing reflections, a phenomenon known as “angle-independent anti-reflection.”
By creating a nanostructured coating in mimicry of the butterfly’s wings, the light from the reader will pass through the implant and give the correct reading independent of the angle.
“The nanostructures unlock the potential of this implant, making it practical for glaucoma patients to test their own eye pressure every day,” Choo says.
As an additional bonus, the nanostructures discourage fouling of the implant by trapping a layer of water around it. According to Vinayak Narasimhan, a graduate student at Calktech working on the project, “Cells attach to an implant by binding with proteins that are adhered to the implant’s surface. The water, however, prevents those proteins from establishing a strong connection on this surface.”
The results of this project were published in the April 30 edition of Nature Nanotechnology. This article is from Research Updates in Optometry. To read more about this interesting prospect check out: Caltechs Article
Lutein and Zeaxanthin are two powerful antioxidants that protect the retina from the damaging effects of UV rays and blue light. These antioxidants can be found in green leafy vegetables. Leafy vegetables also contain vitamin C, E, beta-carotene, and zinc, which are all helpful in preventing the progression of age-related macular degeneration.
This salad features kale, and is a healthy option for good eye health! The recipe is by Optometrists Dr. Barbara Pelletier and Dr. Laurie Capogna who have co-authored books on eye nutrition.
Our eyes are one of our most valuable senses, and we should do our best to protect them however we can. Sun protection is a major component of maintaining your eye health. The sun rays emit several types of harmful light – UVA, UVB, and high-energy blue light. This little infographic gives some handy information, and an idea of how to best protect your eyes.

As a society we spend so much time focusing on screens day through night, and that can greatly impact our eye health! One of the best ways to provide easy protection is to have a blue light anti-glare coating placed on your lenses, which will help protect your retina against harmful damage caused by screens.
What is blue light? Blue light is a natural part of the visible light spectrum, and it accounts for 25% of all sunlight. Blue light has a high amount of energy in each wavelength, and your brain utilizes the natural blue light from the sun to regulate sleep, boost alertness and mood, and contribute to general well-being. It is also produced by electronic screens and energy efficient light bulbs, which is where we are often overexposed and our eyes are prone to damage, which can have serious long term effects. Too much blue light damages the retina, can cause headaches, eye strain and fatigue, difficulties falling asleep, and can ultimately lead to macular degeneration and loss of sight.
Eyestrain is the most common condition associated with computer use, and it can impact productivity and learning ability. Discomfort in the eyes, blurry vision, neck and back pain as well as headaches after computer or screen use is an indicator that you may be exposing yourself to too much blue light. This exposure and damage is irreversible, which is why it is so good to consider protection!
Blue light also impacts sleep! Exposure to blue light decreases your melatonin production, which is a key hormone in healthy sleep and a healthy lifestyle. Using blue light emitting devices just before bed can cause difficulties falling asleep, poor sleep quality, and fatigue upon waking and poor concentration. Lack of sleep is also linked with more serious conditions, so keep yourself healthy and sleep well! Using a pair of glasses with the blue light anti-glare coating can help you avoid these issues. Even if you do not have a prescription you can still get a pair of glasses and lenses that provide protection while utilizing these devices.
Caitlyn LOVES her blue light coating! Prior to having this coating she got migraines quite often, and with this coating the severity and frequency of getting them has dropped. She is now able to spend more time comfortably working and enjoying screen time, without worrying about the strain that is happening to her eyes. It has made a significant difference in her quality of life – how could it impact your quality of life? Talk to us today!
