   For the past few months of not being able to do as much things outside with friends and family, everything from school to chatting with friends has been online and still is for the most part. From this season being online, many have faced problems from technology. One major problem is eye discomfort. So how do we solve this problem? Well, one trending solution that has been going around are blue-light filtering glasses, but the question is do they really work?

     Blue-light filtering glasses have specially crafted lenses that are said to block or filter out the blue-light given off from digital screens. The lenses claim to protect our eyes from glare and can help reduce potential damage to your retina from prolonged exposure to your eye. 

We found that wearing blue-light-filtering glasses is an effective intervention to improve sleep, work engagement, task performance and organizational citizenship behavior, and reduced counterproductive work behavior,”

    Other experts argue that there is no need for blue-light filtering glasses. Not an extreme amount of research has been done on the glasses alone, however there is enough information on the blue light itself that digital screens give off. 

Blue light from electronic devices is not going to increase the risk of macular degeneration or harm any other part of the eye. However, the use of these devices may disrupt sleep or disturb other aspects of your health or circadian rhythm,” says Harvard Health. 

      Although the blue-light from digital screens are not directly harmful to your eyes, you can still experience much discomfort. This can be from looking at the screen for long periods of time, right? Wrong! The discomfort and intensity of looking at screens is from not blinking enough.

“When we stare at a digital screen or device too long , we’re not blinking very often, which causes the cornea to become dry and irritated,” says Dr. Singh.
