Blue Light Protection in Austin, TX

What is blue light and why can it be harmful to my eyes?

We are privileged to live in an advanced age at the turn of the 21st century. Electronic devices are everywhere in our world today and make our everyday interactions with the world around us ever easier, safer and more convenient. Although many positive effects have resulted from these devices in our everyday lives, a darker, more dangerous side exists to all of this progress and convenience. Blue light, also known as high energy visible light, is emitted by many of these electronics and is a serious threat to eye health which was previously unknown and irrelevant in generations past.
Living in such an advanced age, each of us, on average, spends roughly 25 hours every week staring at the screen of one of our electronic devices. To put this in perspective, that means that each of us spends more than one entire day, without sleeping, in front of devices that emit blue light that is proven to do serious damage to our visual system. Eyestrain, headaches, and fatigue are common side effects. Even more alarming, recent studies indicate that blue light exposure has the potential to increase the risk of macular degeneration significantly over time. Those with a history of macular degeneration are at special risk, as well as children, due to large pupils and shorter arms, which cause them to hold electronic devices closer to their faces, both of which allow more blue light to penetrate the eye. In general, the risk of macular degeneration is affected by genetics, diet, and smoking.

What are the ways to avoid blue light exposure to the eyes?

Dr. Bristol likes to suggest to patients a lens that offers blue light protection. The following are a few options on the market and their level of blue light filtering:

·         Eyezen: 20%

·         Prevencia: 20%

·         Transitions: up to 95%

Fortunately, cutting-edge technological solutions to this growing epidemic exist. BluTech Lenses are special lenses specifically designed to selectively filter out blue light, enhancing visual comfort and minimizing eyestrain. These lenses boast a special state-of-the-art filtering agent within the lens material itself that duplicates elements in the eye, called ocular lens pigment and melanin, which the body naturally produces on its own, and which help filter out just the right amount of blue light entering the eye to protect against unfettered blue light penetration, while allowing proper visual contrast.
Recharge is another cutting-edge option to help cut down on the harmful effects of blue light. HOYA is the advanced eye care company that produces these lenses, which reflect up to 30% of harmful blue light away from the eye.
Between the filtering effect of BluTech and the reflective properties of the Recharge coating, a large percentage of otherwise very harmful blue light never reaches the eye. This is an extremely important element in the long-term health of your eyes.
In general, we always recommend that you shift your device into night mode during the evening hours to lower the blue light emission. Patients who spend hours on electronic devices are at increased risk of eyestrain and glare, macular degeneration or problems falling asleep at night.
