Spectral Evaluation of Eyeglass Blocking Efficiency of Ultraviolet/High-energy Visible Blue Light for Ocular Protection.

ABSTRACT:

Significance

We investigated, for safety and awareness, ultraviolet and high-energy violet light-blocking protection provided by assorted types of eyewear. Ultraviolet and high-energy violet light-filtering efficiency varied and did not correlate with price or advertised claims. Standardization of methods and specifications for lens spectral transmission evaluation is recommended.

Purpose

Studies have linked exposure of high-energy visible blue light to effect and damage on retinal epithelial cells, photoreceptors, and ganglion cells. "Blue light" is more accurately differentiated into "high-energy visible blue-violet light" and "circadian rhythm blue-turquoise light." This study measured and compared spectral transmission of ultraviolet and high-energy violet light of low-,
