Blue light glasses are eyeglasses that manufacturers say can effectively filter out blue light from electronic devices. The glasses often have plastic surface coatings or filtering elements on the lens which block a small part of light from passing through. Current studies have not established whether or not blue light-emitting devices are harmful to human vision and eyes. However, many eye doctors and practitioners recommend the use of blue light glasses for several reasons.
For example, if you spend a lot of time working at a computer screen, then blue light glasses work well to eliminate eye strain and other negative effects. In fact, there are several brands of digital screens that contain built-in blue light filters. If you’ve tried these new screens, then you know how effective they can be at reducing or eliminating eye strain and tired eyes. But do keep in mind that if you are using a normal screen, you could need a pair of designated blue light glasses like these from Island Eyewear
The second reason why you may need a pair of non-prescription blue light glasses is to treat macular degeneration. These conditions cause progressive changes to the structure of the eye, as well as to the focusing power of the eyes. As such, it is very important that you get your eyes checked regularly by an eye doctor to make sure that you don’t have any of these conditions. As such, a pair of non-prescription blue light filtering glasses is ideal for this purpose.
What Are The Benefits?
One of the many reasons why blue light glasses can be helpful comes from the fact that they reduce or eliminate one of the main sources of digital eye strain and tension. When you read a book online, watch a movie, or do some computer work, your eyes constantly have to compensate for the amount of blue light you are exposed to. That means that while you are reading or watching something, you might also be squinting. It can actually cause the natural squinting motion to increase, which in turn can increase the digital eye strain even further. But with a pair of non-prescription blue light glasses, you can actually eliminate most of this squinting motion, as well as improve your concentration.
The best part about blue light blocking glasses comes from the fact that they also improve the focus and brightness of the images that you see. It’s true that the normal corrective procedures like eye exercises and other corrective procedures can help improve the focus and brightness of the images that you’re seeing, but they are not always effective. As the years go by, the digital screens that are present on almost all new computers are increasing in size. And because the screens are becoming larger, it becomes more difficult to focus on the screen, especially for those who have presbyopia problems.
