NoIR 3% Dark Amber SpectraShield Small 407-31

Summary

AI-generated from vendor-published content · June 8, 2026

These are therapeutic sunglasses designed for people with extreme light sensitivity — filtering out nearly all visible light (only 3% transmission) while blocking 100% of UV and infrared radiation. The dark amber tint is specifically useful for conditions like retinitis pigmentosa, albinism, or severe photophobia from neurological conditions where standard sunglasses simply don't block enough light. The SpectraShield frame design includes a top ridge and wraparound side shields to eliminate light bleed from above and the sides — a detail that matters a lot when any ambient light causes pain or visual disruption. They fit over prescription glasses, so no separate prescription pair is needed, though at roughly 5.5 inches wide the small size may not fit all frames underneath.

What Setup Looks Like

• Out of the box
  Put them on — worn alone or over existing prescription glasses, no setup required.
• With a guide
  
  1. Confirm the small frame (5.5" wide) fits comfortably over prescription glasses before purchasing — sizing is the main fit variable.
  2. Consult the NoIR filter selection guide to verify the 3% transmission level matches your light sensitivity needs; NoIR publishes filter comparison charts online.
