Your Nights Are Under Attack.
Modern devices bombard your eyes with artificial blue light after sunset. This suppresses melatonin — the hormone that regulates your sleep cycle — leading to restless nights and chronic exhaustion.
The Performance Shield blocks the exact wavelengths (430–550nm) proven to suppress melatonin — without changing how you see or what you do.
Blue Light → Melatonin Suppressed
430–550nm wavelengths trick your brain into daytime mode — melatonin production stops completely.
No Melatonin → Shallow Sleep
Without melatonin you enter sleep but can't reach deep NREM stages. Brain and body never fully restore.
Shallow Sleep → Poor Recovery
Recovery, memory, immunity, and hormones all degrade. Every morning you wake up already behind.
What the Studies Say.
Melatonin suppression from just 2 hours of blue light exposure before bed
Journal of Clinical EndocrinologyDrop in next-day cognitive performance after sleeping under 6 hours of quality deep sleep
Sleep Research InstituteReduction in deep sleep duration for adults who use devices within 1 hour of bedtime
National Sleep FoundationAdults globally suffer from insufficient sleep — chronic sleep deprivation now classified as an epidemic
Vision Science JournalMost Blue-Light Glasses Don't Actually Work.
The Problem with Standard Lenses
Standard "blue light glasses" filter the 380–420nm range — ultraviolet and violet. This helps with eye strain slightly, butdoes nothing to protect melatonin production.The critical sleep-disrupting range is 430–550nm. Most clear lenses block less than 20% of this spectrum. They are selling you a promise they can't keep.
Why Tangerine Shades Are Different
Tangerine Shades use a proprietary 8-layer amber lens system engineered specifically to block 99.9% of the 430–550nm melatonin-suppressing spectrum.This is the exact wavelength range proven by sleep science to be the problem.CR-39 optical-grade lenses. ISO 9001 certified. CE Marked. Every pair independently verified.
The Science Behind Better Sleep.
Three mechanisms. One solution. This is why amber lenses work when nothing else does.
Light Controls Your Biological Clock
Your circadian rhythm is set by light signals hitting ipRGC cells in your retina. These cells are peak-sensitive to 480nm blue-green light — exactly what screens emit after dark.
Blue Light Blocks Melatonin
When 430–550nm light reaches your retina, your pineal gland stops producing melatonin immediately. No amber lens = your brain thinks it's midday even at 11pm.
Block Light. Restore Sleep.
Tangerine Shades block 99.9% of the critical spectrum. Melatonin rises naturally. Sleep pressure builds. You fall asleep faster, stay deeper, wake genuinely recovered.
