Dr. Lim has been a proponent of BluTech Lenses with all his patients. Now he has an opportunity to share his knowledge with the others as well. Our optometrist in San Jose was recently featured on the Radio WCBS in NYC with radio host Pat Farnack talking about the danger or Blue Light.
CBS Interview Pat Farnack
What is it about screens that affect our eyes? Most of us would assume that regular prescription lenses would compensate for everything we need. Not so. The blue light we get from electronic devices creates a special type of blur and strain that cannot be compensated for in normal prescription lenses. I personally use a lens called the 'BluTech' lens. This is a special lens that has a patented material embedded in it that mimics the protective properties of the ocular lens pigment and melanin that we naturally have in our eyes. The lens also has an amber tint, which helps relax the eyes.
People with light colored eyes, like blue or green, are more at risk from the blue light because there is less pigment in their retina to filter this light. It is even more important for these people to have something that helps to filter out blue light, which in turn lessens the strain and relaxes the eye to make it more comfortable. This is an additional protective mechanism for those at risk of macular degeneration.
Exposure to blue light is bad for your overall health - it may disrupt the sleep cycle and can increase the risks for macular degeneration. Some of our patients who use the BluTech lenses find that they can go to sleep more easily.
If you have a history of macular degeneration, you are at an increased risk for it because blue light causes oxidation in the retina at the macula. The BluTech lenses mimic the ocular lens pigment and melanin in our eyes by filtering the harmful high energy blue light.
Kids who spend lots of time on iPads and computers are also at risk. Children have larger pupils, allowing more blue light into their eyes. Because children also have shorter arms, everything is held closer to them, thus increasing their blue light exposure. Children, as well as adults, both need lenses that filter or reflect blue light.
