Is too much blue light bad for your eyes?

You've probably noticed that long screen time leads to tired eyes. Digital devices are typically backlit by LEDs or fluorescent bulbs - both big sources of blue light. Luckily, science could explain why screens can feel so uncomfortable!

We all have special cells in our eyes that are highly sensitive to blue light, In fact, they're most excited around 480-520 nanometers (nm) – the same wavelengths clinical research has found to cause a pain response in people with light sensitivity.

To help soothe your eyes, we recommend taking regular breaks, limiting device usage, and wearing blue light glasses like indoor TheraSpecs that block the most uncomfortable blue light wavelengths.

Since sunlight can hav 250 times more blue light than artificial light sources, outdoor TheraSpecs can provide the same relief and protection when you're out and about!
