Stop ending days with dry, gritty eyes

It is Not You. It is The Light.
If you spend 8+ hours a day on screens, you already know the pattern:
- By 3 PM, your eyes feel like they are burning
- Your focus and energy is shot way before your day is done
- You are scrolling at 2 AM and still cannot fall asleep
- You end every day with dry, gritty eyes
Two to three hours before bed.
Put them on when the evening starts and leave them on. That is the window that matters most.
Real relief for real screen time.
You can still work in them. Colours shift a little, the burn goes away, and you stop fighting your own evening.
Four frames. One job.
Every pair blocks the same 99% of that band. So pick the one you actually want on your face.
Wear them while you still work.
The last two hours of your evening are the ones you spend on a screen anyway. These are made to be worn through them, not instead of them.
Four frames
Pick Your Pair.
All four block the same 99% of that band. The tint label under each name tells you which lens you are getting.
Black square acetate. The plainest of the four.
Black round acetate, keyhole bridge.
Crystal square. The frame disappears, the lens does not.
Tortoise round, warm speckle.
The honest version
What the research supports, and what it does not.
- Supported: evening light suppresses melatonin, and a tinted lens can prevent that.
- Not established: that wearing them makes you sleep better or fall asleep faster.
See the studies
Well supported
- Evening room light suppresses melatonin and delays its onset. It happened in nearly every participant.Gooley et al., Journal of Clinical Endocrinology and Metabolism, 2011. n = 116.
- The receptor driving this is most sensitive between roughly 446 and 484 nm, a narrow slice of visible light.Brainard et al. 2001; Thapan et al. 2001; Bailes and Lucas 2013.
- Orange lenses can prevent that suppression. Under bright light, grey lenses let melatonin fall 46 percent while orange lenses showed no significant drop.Sasseville et al., Journal of Pineal Research, 2006. n = 14.
- An international expert consensus recommends keeping evening light below 10 lux melanopic EDI in the three hours before sleep.Brown et al., PLoS Biology, 2022.
Not established
- That these glasses make you fall asleep faster. The best controlled analysis found a difference of about five minutes, which was not statistically significant.Luna-Rangel et al., Frontiers in Neurology, 2025. Meta-analysis of double blind crossover trials.
- That they improve sleep quality. A 2023 Cochrane review found three trials showing improvement and three showing none, and rated the evidence very low certainty.Singh et al., Cochrane Database of Systematic Reviews, 2023.
- That blue light from screens damages your eyes. There is no trial evidence for this, and we will not claim it.American Academy of Ophthalmology; SCHEER opinion on LEDs, European Commission, 2018.
- That any lens colour is certified as blue blocking. No harmonised European standard exists for it, so nobody can hold that certificate.ISO 8980-3:2022 contains no blue light requirement.
Common Questions.
How much is shipping?
Delivery is free anywhere in Latvia and usually arrives in two to four working days. We do not ship outside Latvia yet.
What is your 30 day guarantee?
Send them back within 30 days and we refund you. Given how mixed the sleep evidence is, a guarantee is the only honest way to sell these.
Do blue light glasses actually work?
It depends what you mean. That a tinted lens removes the wavelengths which suppress melatonin is well measured. That wearing one makes you sleep better is not settled. The evidence section above sets out both sides with sources.
Red or amber?
Red transmits the least light in the band that reaches your body clock. Amber blocks nearly as much while distorting colour less. No trial has compared them head to head, so pick amber for working, red for the last hour.
