Having glasses used to be something pretty straightforward: if you were experiencing difficulties seeing the blackboard at school or the road signs while driving, you would go to an eye doctor, take an exam, then buy glasses if you needed them.
Unfortunately, as society has evolved, so have the different eye conditions. Nowadays, people spend more time in front of a screen, and this is causing new vision problems.
How Computer Glasses Work
Computer glasses are known to be specially built on purpose designed to optimize your sight when seeing different types of digital screens. They are designed to: reduce glare and maximize what is seen through the lenses, making it easier to view a screen for more extended periods since they augment comfort. Here are the two main characteristics you’ll notice in computer glasses or blue light blocking glasses:
Anti-Reflective (AR) Coating – Anti-reflective coatings reduce glare that bounces off screens and light sources. Eyewear specially designed for computers and gaming glasses offer these coatings, and prescription glasses can also get anti-reflective coatings. However, not all anti-reflective coatings are created equal. Older glasses can have a cheap coating that regularly traps stains and dirt, actually causing eye strain and vision problems.
The older ones peel and scratch easily, causing unsightly cracks, so if you tried them a few years ago and had a bad experience, don’t overlook the newer versions. They’ve improved a lot, between being easier to clean and reducing glare.
Color Tints – Some computer glasses or designer eyeglasses also have an incomparable tint (usually yellow) designed to increase contrast on the screen and filter out uncomfortable/harsh light spectra so that the eye muscles relax. Tinted glass is a signature of Gunnar glass, but tints can also be applied to other glasses.
It is one of the most popular web sites to introduce online shopping as augmented reality is getting more and more important day by day. They also have stepped into innovation and technology, they have revolutionized the glasses industry by introducing Ditto. Ditto is a software that can give you the virtual experience of trying eyeglasses on you in 3D. This software works by recording a selfie video and then converting it into a final 3D video with which you will be able to try on hundreds of different styles of glasses.
What about the blue light?
But what about all that blue light we’ve heard about lately? In recent years, we’ve been told that the blue light coming from our phones, tablets, and computers is damaging our eyes, and many companies sell blue light-specific glasses (separate from the coating)
Do not use your devices before going to bed. Research shows that exposure to blue light can prevent you from getting a good night’s sleep.
Take breaks from your devices. Follow the 20-20-20 rule to reduce your risk of digital eye strain symptoms. Rule? Every 20 minutes, take 20 seconds to look at 20 feet.
Get blue light filtering lenses. Computer glasses are known to be specially designed to alleviate digital eye strain and block harmful amounts of blue light coming from the screens you stare at during the day.
Are Computer Glasses Effective?
In order to obtain the maximum visual comfort, the lenses of your computer glasses must include an anti-reflective type of (AR) coating. Sometimes referred to as anti-reflect coating, the AR coating eliminates light reflections from your lenses’ front and back surfaces that can also cause eye strain.
