COIL +12.0, 14 B.I., 45mm, Brown, 1/2 Eye OU14^B10U

Summary

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

These are half-eye prismatic reading spectacles with a 12-diopter lens — a high-powered magnification strength suited for people with significant central vision loss who still have usable peripheral vision. The prismatic element helps redirect the line of sight so the reader can use their strongest remaining field of vision more comfortably, reducing the fatigue that comes from constantly compensating. The 45mm lens sits in the lower half of the frame, leaving the upper portion open for normal distance viewing or navigating the environment. At 12 diopters, the working distance is quite short (around 3-4 inches from the page), so these work best for brief, focused reading tasks rather than extended sessions — and the correct diopter should be confirmed by a low vision specialist, since a wrong prescription at this strength will be uncomfortable and largely useless.

What Setup Looks Like

• Out of the box
  Put on the glasses and hold reading material at approximately 3-4 inches from the lens to find the focal sweet spot.
• With professional help
  
  1. A low vision optometrist or ophthalmologist should assess the appropriate diopter strength before purchase — 12D is a significant magnification and incorrect selection is a common and costly mistake.
  2. An orientation session with a low vision rehabilitation specialist (LVRS) can help the user learn the correct head position and reading distance for prismatic spectacles.
  3. Allow 1-2 clinical appointments before committing to a specific prescription. See manufacturer support resources for detailed instructions.
