Blue Block - For Children
Nowadays children use smartphones, tablets on a daily basis and watch TV for several hours. As a result, they are exposed to the "blue light" the emit.
What is "blue light"?
It's part of the electromagnetic radiation which has s short wavelength. The use of the above devices long-term, causes eye strain and the risk of long-term health effects, as it can damage light-sensitive cells with the possibility of vision loss.
Our eyes aren't particularly "effective" in filtering. It's recommended to use glasses with special lenses (Blue Block), which filter a significant amount of blue light emitted by digital devices, without affecting the visibility of the screen.
