Ra Optics Blue Light Blocking Glasses

Artificial blue light tricks your brain into believing it’s still daytime and that you should be awake, not asleep.

Scientists worldwide are now warning of the dangers of night-time exposure to artificial, blue light. Ra Optics, is hands down, the BEST blue light protection eyewear I’ve found.” — Ben
