Your Phone Is Delaying Your Sleep by 1–3 Hours Every Night.
Blue light from screens — phones, laptops, TVs — hits the short-wavelength receptors in your retinas and signals your suprachiasmatic nucleus to suppress melatonin. This isn't a minor effect. Research consistently shows 1–3 hours of melatonin delay from evening screen exposure, which means your body isn't ready to sleep when you lie down, regardless of how tired you feel.
Blue Light Blocking Glasses filter the 400–480nm wavelengths responsible for that suppression. Worn in the 1–2 hours before bed, they allow your body's natural melatonin ramp to proceed on schedule — so by the time you're in bed, your biology is actually ready.
Why It Works
Filters 400–480nm blue light wavelengths — the specific spectrum that suppresses melatonin production
Amber-tinted lenses provide high-efficacy blocking without distorting color beyond usability

In the Rest Theory Stack
This product addresses: Light
The Mulberry Silk Sleep Mask handles light once you're in bed. These glasses handle the pre-sleep light problem — the 1–2 hours before bed where screen exposure is actively working against your melatonin cycle. Together they close the light variable across the full evening window. Pair with Sleep Strips for a complete pre-sleep protocol.
