Do blue light glasses help with eye strain or headaches?
The best evidence says they may not help with eye strain. A 2023 Cochrane review found that blue-light filtering lenses may not reduce eye strain from computer use over the short term. Where blue light matters is the evening, when it can push the body clock, and sleep, later. That is the job sleep glasses do.

What did the review find?
The Cochrane review compared blue-light filtering lenses with ordinary lenses. It found they may not reduce symptoms of eye strain with computer use, over a short-term follow-up.
What about headaches?
SleepSpec is not made or sold for headaches. It is made for one job: the light in the hours before bed.
So what are blue light glasses good for?
The evening. Blue-rich light can suppress melatonin and push the body clock, and sleep, later. Deep-amber lenses filter it: SleepSpec blocks 98% of blue-green light across 400–520 nm, and you keep using your screens. In adults with insomnia symptoms, amber lenses were linked to approximately 29 minutes more actigraphy-estimated sleep and improved insomnia scores. The study did not test SleepSpec, and individual results vary.
