NoIR 87% Yellow SpectraShield Large 450-38/39

Summary

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

These are specialty low-vision filter glasses with a light yellow tint that blocks 100% of UV and blue light while allowing 87% of visible light to pass through — one of the highest light transmission levels in NoIR's range, designed for people who need contrast enhancement without significant dimming. They're a good fit for someone with macular degeneration, glare sensitivity, or other low-vision conditions who struggles in bright light or fluctuating lighting environments but still needs maximum usable vision. The SpectraShield wraparound frame includes a top ledge to block overhead light and tinted side windows to prevent lateral glare, and can be worn directly over most prescription eyeglasses. The yellow tint, while subtle, does shift color perception, so tasks that require accurate color judgment may be affected.

What Setup Looks Like

• Out of the box
  
  1. Put the glasses on — they can be worn directly over existing prescription glasses.
  2. No adjustment or charging needed; ready to use immediately.
• With professional help
  
  1. An optometrist or low-vision specialist can help determine whether yellow (87% transmission) is the right filter color and transmission level for your specific condition and lighting environments.
  2. If you have macular degeneration or another progressive eye condition, a low-vision evaluation is recommended to select the most beneficial filter from NoIR's full range.
