A recent study done by The University of Toledo showed that blue light could turn the retinal molecules in our eyes toxic. These vital molecules in your eye’s retina are turned into cell killers, according to the chemistry research done at the University of Toledo. That doesn’t necessarily mean you are going to go blind just because you are exposed to blue light.
Where To Buy Computer Glasses With Blue Light Protection
Digital devices such as smartphones, tablets, computers, and televisions emit this dangerous blue light, which could not only impact your eyes, but it could potentially affect your overall health.
Technology is here to stay. There is almost no way to go throughout your day without encountering some sort of digital device, whether it is at work, at home, or even at restaurants. But just as it is important to wear sunglasses when you are outside, it is just as important to take protective measures for your eyes when you are using digital devices. Using prescription or non-prescription computer glasses with blue light protection is a good way to protect your eyes from the harmful blue light.
What is Blue Light?
Blue light is a part of what is known as the visible light spectrum. Sunlight is made up of violet, indigo, blue, green, yellow, orange, and red. Whenever all of these light colors are combined, it becomes the visible light that you see. Blue light is on the end of the spectrum where the light waves are shorter, but they pack more energy than the red on the opposite side of the spectrum.
The sun is the single largest source of blue light, but the reason why digital devices are a concern is the length of time people spend on them, and the close proximity of the devices. While blue light is often associate with digital devices, fluorescent light, and LED light also emit blue light, according to the American Academy of Ophthalmology.
Not to be Confused with Digital Eye Strain
Some individuals who work in front of a computer screen all day may feel like their eyes are itchy, dry and red after a long day. This is a symptom of digital eye strain from focusing on the computer screen for extended periods of time. This happens due to us naturally blinking less whenever we focus on anything. This could even happen from reading a book.
The best way to relieve digital eye strain is to follow the 20-20-20 rule. In this rule, you look away from whatever you are focusing on every 20 minutes, for 20 seconds, 20 feet away. This helps gives your eyes a bit of a break and helps your eyes refocus, and would help with the symptoms of digital eye strain.
Computer Glasses with Blue Light Protection
As more and more information comes out about the potential hazards of blue light, blue light protecting glasses have gotten more popular. People looking to help reduce digital eye strain, and avoid disrupting your sleep/wake cycle.
If you wear prescription glasses, many optical retailers offer a blue light protection coating that can be added to your lenses.
If you do not wear prescription glasses you are still able to protect your eyes. There are many retailers that sell non-prescription glasses that come with blue light protection. You can even get magnified reading glasses with blue light protection as well.
Do They Work? They Totally do!
I have worn glasses for the better part of my life. I was blessed with eyes that have high astigmatism. Which makes me extremely sensitive to any kind of glare. I have worn glasses that have an anti-reflective coating for most of my life, and have since purchased glasses that have a blue light protection coating and it is totally worth it!
Although there is no true research done on how effective blue light blocking glasses work against digital eye strain. I work on the computer for extended periods of time for 12-15 hours a day. Not only that, when I take a break from working on the computer I find myself staring at my smartphone. Wearing glasses with blue light protection helped my eyes feel more rested and relaxed at the end of my day.
Also, since that recent study by The University of Toledo has shown what blue light could potentially do to the cells in your eyes, I think filtering out as much artificial blue light from artificial sources would be beneficial. The other option would be to avoid these sources, but we all know that we’re not giving up our smartphones.
