NoIR 11% Dark Gray SpectraShield Large 422-38/39

Summary

AI-generated from vendor-published content · April 26, 2026

These are specialized wraparound sunglasses with a dark gray tint that blocks 100% of UV light and blue light while allowing only 11% of visible light through — a significant light reduction designed to reduce glare and improve contrast for people with light-sensitive eyes. They're well-suited for someone with conditions like glaucoma, cataracts, or diabetic retinopathy who finds bright sunlight or artificial lighting uncomfortable or visually disorienting. The SpectraShield frame design includes a ridge along the top to block overhead light and tinted side panels to prevent light from entering at angles, and the glasses are large enough to fit directly over most prescription eyewear. At 11% transmission, these are among the darker filters in the NoIR line — worth noting if you need to see clearly in dimmer conditions like shaded areas or indoors, where this level of tint may be too dark.

What Setup Looks Like

• Out of the box
  
  1. Put on the glasses — they can be worn alone or over existing prescription glasses.
  2. Step outdoors or into bright light to assess glare reduction and comfort.
• With professional help
  
  1. A low vision specialist or optometrist familiar with NoIR filters can help determine whether 11% transmission is the right darkness level for your specific diagnosis and light sensitivity.
  2. If you have a diagnosed condition like glaucoma or macular degeneration, consult your eye care provider before selecting a filter — wrong tint density can affect safety and visual function.
