Blue light glasses are specialized eyewear that filters out blue light and increases contrast. Blue light is emitted by digital devices such as computers, smartphones, and LED lights, and prolonged exposure to it can cause eye strain, loss of focus, and other symptoms. Blue light glasses are designed to block or filter out blue light, which can reduce eye strain, eye damage, and sleep disturbances. Here are some benefits of blue light glasses:
-
Reduced eye strain: Blue light glasses can reduce eye fatigue and the symptoms that come with it, such as headaches and blurred vision.
-
Better sleep: Blue light lenses can help signal to our bodies that its time to wind down and prepare for a restful sleep. Blue light lenses block blue light to minimize its impact on your circadian rhythm, which is particularly important for those who spend a lot of time using digital screens or in LED-lit rooms.
-
Prevention of age-related macular degeneration: Some preliminary studies indicate that blue-light blocking glasses can mitigate damage that will cause problems later in life.
-
Reduced glare: Blue light glasses can also be beneficial for outdoor use, such as when engaging in activities in direct sunlight. These lenses help reduce glare and make it easier to focus on your activity or enjoy the scenery around you.
While there isnt a lot of research to back up the claim that blue light glasses actually reduce eyestrain, eye damage, and affected sleep, they can still be helpful for reducing blue light exposure. Its important to be mindful of your total amount of blue light exposure, regardless of whether or not you use blue light glasses.
