Blue light is all around us today. Prior to cell phones, blue light was only prevalent in televisions, for the majority of people. But today blue light is all around us. In the natural world, our eyes are exposed to all the different waves of light, and our bodies and eyes are designed to live in that world.
Our bodies are designed to respond to light in different ways. Sunlight triggers Vitamin D production increases serotonin levels and triggers the mitochondria in our cells to start energy production. But when we stare at blue light, such as looking at screens all day, a very small wavelength ends up monopolizing the cells that respond to light to act in unhealthy ways, such as lowering melatonin production at night. There is even a link between blue light exposure and lowered Vitamin B12 levels. Following are some of the best ways to protect your eye from blue light.
Use Blue Light Blocking Software
Some of the best blue light blocking software includes Flux, Nightshift, and Iris. Flux and Nightshift are free software, while Iris is paid software with a trial version. Flux is the best free choice because you can specify the level of warm or red light you want. Under the settings in iPhones, you also have the option to turn on night mode, which blocks blue light.
Use Dark Mode on Your Computer and Phone
Set the theme and background of your computer and phone to dark mode. The more white light and bright colors being emitted from your screen, the more blue light comes from it. Most computers and devices have an option for dark mode.
Wear Blue Light Blocking Lenses
There are now blue light blocking eyeglasses that you can ask your eye doctor about. These are very comfortable and do a lot to keep eyes shielded from blue light while you’re working on your computer at home or at work.
Blue light is a prominent danger to your eye health today. Making a little effort to block blue light from your devices as much as possible will help protect your eyes. With these steps in mind blue light won’t be completely gone, but it will be at a level that is less threatening.
