COIL +4.0, 6 B.I., 49mm, Brown, 1/2 Eye OU6^B10U

Summary

AI-generated from vendor-published content · June 7, 2026

Half-eye prismatic reading glasses with 4-diopter lenses designed for people with low vision who need magnification without a full-field lens. The prismatic design redirects light to help people with central vision loss use their remaining peripheral vision more effectively — a common approach for macular degeneration. These are complete, ready-to-wear glasses: no charging, no setup, no accessories required. At 49mm, the lenses are on the larger end for this style, which gives more usable viewing area. The tradeoff: half-eye readers sit low on the nose and work best for near-range tasks like reading — they're not meant for general distance vision or extended computer use.

What Setup Looks Like

• Out of the box
  
  1. Put on the glasses and position reading material at approximately 10 inches away (the focal length for 4 diopters).
  2. Adjust nose position so that you're looking through the lower half of the lens for near tasks.
• With professional help
  A low vision optometrist or optician can verify the correct diopter strength and check prismatic alignment for your specific vision needs — strongly recommended before purchase if you haven't had a recent low vision evaluation.
