Do Blue Light Glasses Actually Work?

Computer glasses are a specialized type of eyewear that helps reduce the symptoms associated with computer vision syndrome. The signs and symptoms are burning, dryness, or redness in the eyes; blurred vision; headaches; neck, back, or shoulder pain. And sometimes it can even affect your performance at work because many people look at their laptops for long periods without resting their eyes.


And they're not just for adults! Computer glasses work well for children because they can create more space between their eyes and the screen to avoid any squinting or wrinkling of the eye's outer lining (cornea). This is called "near-point stress" and it's just as harmful to their vision as it is for adults.

If you are a computer worker, have an avid gamer in the house, or if you have children who use computers at school for extended periods of time, you should know that extended exposure to blue light emitted from computer screens can damage the retina. Computer glasses reduce the level of blue light entering your eyes and protect your retina. This can prevent computer vision syndrome from getting worse, and it can help keep your vision clear.


Computer glasses are a great option to protect you or a loved one's eyes from the potentially damaging effects of blue light. But even with computer glasses to block out blue light, there are still other things you can do to help your eyes stay healthy. So if you're at work, do your eyes a favor and take frequent breaks (at least every 20 minutes), set an alarm to remind yourself when it's time to look away from the screen or better yet, follow the 20-20-20 rule as often as possible: Every 20 minutes look at something 20 feet away for 20 seconds.

The Benefits of computer glasses


Computer glasses can help reduce headaches, eye strain and dry eyes caused by prolonged periods of computer work. Computer glasses can be a good solution for those who spend long hours before the computer screen or looking at digital screens such as smartphones. 

The light rays emitted by these devices stimulate the cones and rods in our eyes, which strains our sight if we do it for a prolonged period.


Computer glasses block out harmful light emissions and prevent them from entering your eyes. They help to reduce discomfort so that you can continue using the device for an extended period without worrying about your eye health. They are especially beneficial to those who use digital devices at night because the blue light emission from these devices is more harmful than regular computer use.


How Long Can You Wear Computer Glasses?


Computer glasses can help reduce the symptoms of computer vision syndrome, but you still need to take other steps to protect your eyes from damage. Computer glasses should be worn only at least 20 minutes at a time and then you must remove the device for at least 20 minutes. If computer glasses are worn for longer periods, this can lead to eye fatigue and can make your eyes more susceptible to damage caused by the constant use of digital devices.


How can I tell if my Computer Glasses are helping?


Computer glasses are not meant to cure any eye problems, but they do block harmful blue light emitted from digital devices. After continued use of computer glasses, you should notice that your vision problems have improved less frequently, if at all.
