What is Blue Light?

Sunlight is the main source of blue light, but there are also many man-made indoor sources of blue light, including fluorescent and LED lighting and flat-screen televisions. Most notably, the screens of computers, tablets, smartphones and other digital devices emit significant amounts of blue light. And with the amount of time spent using devices on the increase, there are many long-term effects of blue light on eye health. 

Why do we need blue light control?

Blue light scatters more easily than other visible light, so when you're looking at computer screens and other digital devices that emit significant amounts of blue light, this visual "noise" reduces contrast and can contribute to digital eye strain.

Protective eyewear

If you are frequently using your phone, a convenient way to reduce your exposure to blue light is to wear glasses with blue light control lenses. These can be worn with or without a prescription, and prevent significant amounts of blue light from smartphones, tablets and computer screens, without affecting the visibility of the display. Some people find that glasses with a blue light filter can prevent them from feeling restless and tired, and provide a more comfortable vision. 

Don't just take our word for it, try it for yourself...

Just select the "build your own option" at the prescription checkout and add on blue light control.
