We all know that our smartphones and other devices like a laptop, desktop, tab, etc leave a blue light and if you constantly look into it, it can eventually lead to blindness. Yes, the American University of Toledo has revealed this fact in a recent research. The research says that the light can affect cells in your eyes, potentially leading to macular degeneration, a major cause of blindness.
However, many devices from manufacturers like Apple, Google, and Amazon have blue light filters and you can easily turn them on from settings.
Moreover, doctors recommend not to use these devices in the dark and use sunglasses filtering UV and blue light. The research also discloses that blue light also affects your sleep. These devices also leave UV rays and that too is very dangerous for eyes.
