In the last couple of decades, there have been many studies that emphasize how the blue light from computer screens have detrimental effects on our health. Lack of sleep, loss of vision, and even mood problems have all be associated with spending a substantial amount of time staring at a computer screen. Unfortunately, in this day and age, there are not that many jobs that don’t require being behind a computer screen for at least a considerable amount of time. This is why a new technology has been flooding the markets in order to reduce the negative effects that computer screens and blue light have on people. this technology comes in the form of polarized blue light glasses, more commonly known simply as “computer glasses”.
Computer glasses are just like regular glasses, only they do not have any augmentation and you don’t need a prescription to get them. They are also coated with a special lens technology that effectively filters blue light and provides the user with protection from the damaging effects of computer screens. The use of polarized sunglasses technology also relieves major eye strain experienced by most computer users. This eye strain can be caused by many factors. Normally, if you’re under the age of 40 and have experienced blurry vision and headaches when looking at a computer screen, it may be because your eyes have trouble focusing and switching the focus from your screen to your keyboard for a prolonged period of time. This can cause major headaches and even worsen your vision over time.
In order to provide the best viewing comfort, computer glasses must have an anti-reflective coating, which is sometimes also known as an anti-glare treatment. This coating prevents light from reflecting from the front and back surfaces of your lenses, which would make for an uncomfortable field of view. An anti-blue light can also help colors on your screen appear more vibrant and truer to what they actually should look like, since blue light actually decreases your visual spectrum.
When choosing computer glasses, you may want to go with the over the counter kind, just to try them out. There are various websites dedicated to computer glasses and they have all sorts of different frames and styles to choose from. You can also ask your optometrist for a prescription. If you already have vision problems and wear glasses or contacts, the best thing to do would be to ask for a prescription. This way you can guarantee that your glasses will not only be blue light reflective but also equipped with your pre-existing prescription. Many of the websites that sell nonprescription computer glasses are also able to fill your prescription for you.
A little-known fact is that blue light reflection coatings are not only useful when looking at a computer screen. Although that is what they are mainly designed for, you can also grab a pair of blue light coated sunglasses if you’re interested in blocking out blue light from the outside as well.
