Blue light is a type of visible light with a short wavelength produced by technology, such as smartphones and computers, as well as a clear sky. While a certain amount of blue light exposure is natural, too much can adversely affect eye health and sleep. Thankfully, there is a solution to protect vision in the modern world: blue light glasses. Your optician can help you choose the best pair for your circumstances to improve and protect your eye health.

What Are Blue Light Glasses?

Blue light glasses partially filter blue light through a special coating on the lens surface. Opticians often recommend them to those who spend a large portion of their days working on digital screens.

The glasses range in color from yellow to dark red. Typically, the darker the tint falls on this spectrum, the more blue light will be absorbed. In general, darker lenses are preferable for nighttime use, while clearer ones allow for better visibility during the day.

For those who wear corrective eyewear, a prescription will be necessary for blue light glasses.

What Are the Benefits of Wearing Them?

Before computers, smartphones, and other technology became a big part of human life, blue light was only visible during the day. Naturally, it became associated with alertness and productivity, whereas darkness became associated with sleep. Thus, exposure to blue light throughout the day confuses the body’s circadian rhythm— its sleep and waking cycle—making it difficult to fall asleep and wake up. Blue light glasses can make it possible to work or relax in front of a screen without worrying about affecting sleep quality.
Because blue light scatters throughout the eye, it creates digital eye strain, reducing visual contrast and making it harder to see clearly. In straining to focus, eyes might also become dry and irritated. Tears serve as a protective layer for the eyes, so dryness might increase the risk of infection, especially as you rub at irritation and introduce bacteria. Blue light glasses will reduce digital eye strain and hinder rubbing for healthier eyes.
