A Blue Light Filter blocks a portion of blue light.

​

Blue Light is naturally found in sunlight.  Blue Light regulates our sleepiness and alertness cycles. The sun produces significantly more blue light than electronic sources, but now more than ever, we’re exposed to artificial blue light from our devices, such as mobile phones, iPads and PC monitors.

​

Many of us spend upwards of 6 hours a day either on a computer and electronic devices, potentially exposing ourselves to blue light even after the sun goes down.

​

The blue light can trick your body into believing it’s still daytime, which may stop you from feeling fully sleepy or impact your sleep cycle.

​

Even if you don’t require prescription lenses, Blue Light lenses can be fitted to your choice of frames, providing you with a pair of “screen glasses”.
