Harmful Effects of Artificial Blue Light at Night
- Disrupted Circadian Rhythm: How exposure to artificial blue light from screens/devices after sunset suppresses melatonin, leading to sleep disturbances.
- Increases ROS and inflammation
- Raises blood sugar and insulin
- Damages the retina and can lead to macular degeneration
- Chronically raises cortisol which can lead to hormonal imbalances such as low testosterone
- Damages the mitochondria
- Can damage skin (we have blue light photoreceptors called melanopsin in retina and in skin)
Benefits of Blue Light Blocking Glasses
- Improved Sleep Quality: optimzes melatonin secretion at night
- Helps maintain healthy hormone levels
- Helps to reduce inflammation from chronic artificial blue light exposure
- Helps reduce eye strain during extended screen time.
- Day and Night Use:
- Daytime glasses: Emphasize blocking excessive blue light indoors while allowing natural blue light for energy and alertness (day time glasses used if on screen all throughout the day), blocks 400-450nm, 90% of general blue, reduces dark circles under eyes
- Nighttime: Promote glasses red lenses for effective melatonin preservation and completely blocking the blue frequency(400-570nm)
- Best to wear the night glasses right after sunset

Frequently Asked Questions
-
Three tiers, three windows:
- Daytime / screen use (yellow or orange lens) — for computer and phone time during the day. Cuts the high-energy blue peak without distorting colors so much you can't work.
- Evening (orange lens) — 2–3 hours before bed. More aggressive blue block, still usable around the house.
- Red lens (deep-night) — 1 hour before bed and into the night. Blocks blue and green. This is the strictest tier.
Most people who go all-in own two pairs: a daytime tier and a red tier. If you're only buying one, start with the red.

Every lens tier gets bench-verified on a spectrometer before the spec goes live on the site. The red tier holds 100% block past 570 nm across the calibrated blue and green range. What we publish is what the lens does. Pair after pair — not one hero sample.
The test curves are public. If you want to see them, email info@emr-tek.com and we'll send the spectrometer reports.

Off-the-shelf tiers (red, orange, yellow): US orders ship in 1–2 business days, 3–5 days to your door. Free shipping over $99. International ships duty-free worldwide — no surprise customs bill.
Prescription pairs: Each pair gets individually made to your script, so shipping takes longer — typically 2–3 weeks from order to delivery.
If the tier or fit isn't right, send them back within 30 days for a full refund. No restocking fees. Most returns are actually tier swaps (red for orange, usually) — email support before shipping back and we'll handle the exchange directly so you're not paying return shipping twice. -
Don't drive in the red tier — color perception shifts too far for safe driving (red/green traffic lights get weird). Use the yellow or orange tier for driving at night if you need one.
For work, the red lenses are fine for reading, talking, watching TV, or anything around the house. For color-accurate work (design, photo, video editing) use the yellow tier during the workday and switch to red when you're winding down.
