Effects of Red and Infrared Light (640-940nm) on Cataract Formation in Humans in the Absence of UV Light

Date: March 11, 2025

Executive Summary

This report examines whether red and infrared light in the wavelength range of 640-940nm can cause cataracts in humans when UV light is absent. After analyzing multiple scientific studies, safety guidelines, and expert opinions, the evidence suggests that red and infrared light within this range is unlikely to cause cataracts under normal exposure conditions. The primary mechanism for cataract formation from light exposure appears to be thermal rather than photochemical for these wavelengths. While high-intensity exposure could potentially cause thermal damage, typical therapeutic and environmental exposures fall well below established safety thresholds. Individuals with pre-existing eye conditions or those using photosensitizing medications should exercise caution, but for most people, exposure to red and infrared light (640-940nm) does not present a sign
