Blue light is a type of light categorised as high energy visible (HEV) light. It has the shortest wavelength and highest energy in the visible spectrum and sits between harmful UV light and less harmful visible light.
The reality is that blue light is all around us. The majority of the blue light we are exposed to comes from the sun, but more recent lifestyle changes means that we are now also exposed to artificial sources of blue light in doors, such as LED lighting, computer screen and mobile devices.
High energy blue light can be considered both good and bad for us. We do require some level of blue light to help our body know when to sleep and when to wake, in other words regulate our circadian rhythm and exposure to blue light can also aid memory and improve mood. However, over-exposure to blue light is thought by some to contribute to digital eye strain, interruptions to our natural sleep cycle and longer-term eye health conditions and there is significant research underway in this area.
Blue light glasses with UVBlue or UVBlue+ lenses are for anyone looking to maintain the long-term health of their eyes. Blue light glasses with UVBlue+ are for those looking to reduce the effects reflected light from LED lighting, digital devices or computer screens, which can contribute to digital eye strain.
Our blue light glasses use UV+420 technology dispersed in the lens material itself, to filter a portion of high energy blue light whilst also providing UV protection.
In addition to the great benefits of our UVBlue lens, our UVBlue+ lens has a blue multi-layer anti-reflection coating that filters an extra portion of blue light above 420nm have a blue hue to the lens.
