Sleep Protocol Database - FAQ
Will the clip-ons scratch my glasses?
No. The clamping mechanism is coated in a soft, industrial-grade rubber compound. Metal never touches glass.
Why are the lenses red?
VisionAfter7 Red lenses block 100% of Blue and Green light (up to 550nm). Clear or yellow lenses only block 20-60%, which is not enough to prevent melatonin suppression.
How long does shipping take?
We use NinjaVan for all local Singapore deliveries. Delivery typically takes 1-3 Business Days.
Can I drive with these on?
Absolutely NOT. These lenses filter out green light, making traffic signals invisible. Strictly for indoor, stationary use only.
What is the 30-Night Guarantee?
Wear them every night for 30 days. If you don't track better sleep or feel more rested, return them to our Singapore warehouse for a full refund.
