Damaging effects of digital devices on our eyes – and what you can do about it

by David Burgett on
Exciting changes in glasses technology are happening fast. Do you remember what your cell phone was like 5 years ago? Similar advancements in glasses make our lenses lighter, stronger and last longer. But sometimes there is a negative side to quickly changing technology. These days we all are looking at digital screens (phone, tablet, computer monitor and TV) for over 6 hours a day (and sometimes much more), and new research shows the harmful effects on our eyes and brain from the blue wavelength light. By staring at digital screens, we blink less, leading to the eyes drying out. Also, the blue light actually makes us over-focus, making our eyes work even harder and thereby causing eye fatigue, strain and tired eyes. Studies show how blue light actually disrupts our sleep by suppressing the production of melatonin. Moreover, the constant bombardment of blue light from digital devices can damage the light-sensitive cells in the retina, thereby increasing the risk for a sight-threatening condition called macular degeneration. Thankfully, at AVC we can order your glasses with the latest blue light filter to reduce the amount of blue light that enters your eyes. The filter is transparent, so it won’t change the color or tint of the lenses in your glasses. Interestingly, if you get transition lenses they will also filter damaging blue light even when you are indoors and the lenses are clear. When you think about the total number of hours per day we stare at a digital screen, it’s scary how often our retinas are exposed to the harmful effects, and we are only beginning to discover the full extent of the damage caused by blue light. As quickly as we discover them, we are finding solutions to reduce those negative effects, and at AVC we keep at the forefront of technology to make sure you are getting the best protection based on the latest research.
