Blue Light Blocking Glasses

Do you get headaches after working at your computer station for hours at a time? For that matter, do your eyes ache after spending all day working at and communicating using digital devices? If this is you, there are some things that you can do. First of all, have you heard about blue light blocking glasses? If you have, you are perhaps under the mistaken impression that they are yellow lenses and frames that only a geek would be caught dead wearing. Today’s blue light blocking glasses come in designer frames, if that is your wish, and they can look pretty normal or downright classy.

Why Is Blue Light Filtering Useful?

We mentioned headaches and aching eyes. Computer vision syndrome is a condition of the modern digital age. As many as 90% of those who work at a computer most of the day experience tired eyes and headaches. When you work involves computer use for much of the day this may seem like an unavoidable condition. But, it isn’t. The first line of defense is common sense. Simply look away from the computer every so often. If you want to be formal about it, use the 20-20-20 rule. Every twenty minutes look away from your computer or tablet or smartphone screen.Look at something at least twenty feet away. And, keep looking away for at least twenty seconds. This little exercise in common sense will reduce a lot of the problem. But, you are still spending hours at a time looking at that screen. That can be a problem because of the nature of the light coming from the screen! The long term answer is to use blue light blocking glasses to routinely reduce the high energy blue light that is part of why your eyes are tired and why you are getting those headaches.

High-Energy Blue Light and Lack of Sleep

Blue light is the part of the visual spectrum right next to ultraviolet light. These are the light wavelengths that carry the most energy. The LEDs used in computer screens have a higher proportion of blue light that sunlight and certainly more than other artificial light sources. You would think that the problems with blue light and computers would stay at work but now that everyone has a mobile device, we bring the blue light home with us too. The same 20-20-20 rule is useful at home as are blue light blocking glasses. Otherwise, your daytime headaches and eye strain will be compounded by lack of sleep at night! The blue light filter in your glasses blocks blue light and allows your brain to produce a substance called melatonin that paves the way (in the brain) to a good night’s sleep. Why you should worry about blue light is because it upsets the circadian rhythm that lets the brain turn from daytime activity tonight time repair, memory processing, and other necessary functions.

Taking a break from digital device usage starting an hour or so before bedtime is a good idea. But, a better idea is to use blue light filter glasses eye protection for evening“screen time” just like during the day.

Your Eyes and Long Term Blue Light Exposure

There is an eye condition called macular degeneration. It is the leading cause of legal blindness, which is corrected vision that is no better than 20/200 in the better eye. The macula is the center of the retina where most of our color vision is located and where we see the things we are looking. When this area is damaged, as in macular degeneration, people essentially have a big blind spot in the center of their vision but have the ability to perceive light and object in the periphery. Unfortunately, when the person tries to look at something that shows up in their peripheral vision, they move their eyes to see. Then,that object in now hidden in the central blind spot.

Macular degeneration is most common in the elderly because they have had more years of slow but steady damage to the macula of the eye. New research indicates that blue light, the high-energy part of the spectrum can be at fault for accelerating this condition. A concern that goes with this finding is that we are now exposed and our children are exposed to concentrated blue light from the digital devices that have become integral parts of our lives. So, what does blue light damage in the eye? It has been shown to damage them itochondria which are the little energy factors necessary for every cell in the human body to live and function. While looking away from your computer or smartphone for a bit can be an excellent way to reduce eye strain and headaches, it does not negate the effects of hours looking at a digital device screen. Here is where blue light filtering is necessary. And, the handiest,most portable way to do this is with blue light blocking glasses.
