Blue light glasses are eyeglasses with lenses that have a special coating or tint designed to reflect or block blue light from reaching your eyes. Blue light is a wavelength that is naturally present in light, including light from the sun and digital devices like laptops, smartphones, and LED lights. Compared to other light types, blue light has a short wavelength, which can cause eye strain, headaches, and insomnia. Blue light glasses can help reduce exposure to blue light waves that can keep you awake, especially if you use these glasses when looking at a screen, especially after dark.
Some of the benefits of blue light glasses include:
-
Reduced eye strain: Blue light glasses can reduce eyestrain caused by prolonged exposure to blue light from digital devices.
-
Improved sleep: Exposure to blue light, particularly during the evening, has been shown to disrupt melatonin production, the hormone responsible for regulating sleep. Blue light glasses can help reduce exposure to blue light waves that can keep you awake, especially if you use these glasses when looking at a screen, especially after dark.
-
Reduced risk of eye damage: Blue light glasses can reduce the risk of eye damage caused by prolonged exposure to blue light.
Blue light glasses are available as prescription lenses, over-the-counter reading glasses, and glasses that are only used for the purpose of blocking blue light. When choosing blue light glasses, it is important to consider factors such as comfort, lightweight, and fit. However, there isnt a lot of research to back up the claim that blue light glasses actually reduce eyestrain, eye damage, and affected sleep.
