Researchers find that blue light from smartphones may not negatively effect sleep

So how do these gadgets impact vision? The 'blue light' that emanates from the gadgets could be the solution.

Although blue light occurs naturally in sunlight, we are more frequently exposed to it through the use of tablets, cellphones, and televisions.#bluelightglasses #glassesforkids #bluelightbloc
