Blue light blocking lenses can help to alleviate a variety of symptoms associated with prolonged screen use. We've listed the main ones below.
Blue light tells our body when we need to be awake. That's why looking at screens during the evening can interfere with the production of melatonin, the chemical responsible for helping you sleep.
Studies show that blue light blocking lenses can help you maintain a normal circadian rhythm, and help you get better quality sleep.
Our eyes muscles have to work harder to process text and images on screens because it is made up of pixels. Your eyes react to changing images on the screen so your brain can process what you’re seeing. All these movements require a lot of effort from your eye muscles. Unlike paper, the screen adds contrast, flicker, and glare, which makes our eyes work even harder.
Coolblu blue light blocking lenses also come with an anti-reflective coating. This helps to make your eyes feel more comfortable by reducing the glare that screens create.
In the same way that UV light can harm our cornea and skin, there are more and more studies that are linking an overexposure of blue light to macular degeneration.
The macula is part of the retina. It's a crucial part of our vision and without it, we cannot see. There are eye doctors that believe the overexposure to blue light, due to our dependency on digital devices, can damage our retina. Some of them reference the growing number of macular degeneration cases, as well as the fact that people now develop it at younger ages.
Blue light blocking lenses can help reduce the risk of macular degeneration. And while research may still be in its early stages, it's always better to be safe than sorry.
