MetroSunnies Launches a New Innovative Con-Strain Glasses for Smartphones

Introducing MetroSunnies' Con-Strain, the first collection of blue light glasses. These frames are equipped with anti-radiation and blue light protection lens that help prevent headaches, dry eyes and digital eye strains.


Sunlight is the main source of blue light, and being outdoors during daylight is where we get most of our exposure to it. But there are also many man-made, indoor sources of blue light, including fluorescent and LED lighting and flat-screen televisions.


Most notably, the display screens of computers, tablets, smartphones and other digital devices emit significant amounts of blue light.


The amount of HEV light these devices emit is only a fraction of that emitted by the sun. But the amount of time people spend using these devices and the proximity of these screens to the user’s face have many eye doctors and other health care professionals concerned about possible long-term effects of blue light from computers and phones on eye health.


High-energy blue light rays scatter more easily than other visible light rays when they strike air and water molecules in the atmosphere. The higher degree of scattering of these rays is what makes a cloudless sky look blue.
