Offering a blue light filtering intraocular lens (IOL) to patients undergoing cataract surgery is a significant advance in the quality of patient care. In the 1980s, UV light–absorbing IOLs were introduced and rapidly became the standard of care.¹ UV light was identified as a potential retinal hazard and these new lenses were designed to mimic the UV filtering properties of the normal crystalline lens that absorbs light between 300 nm and 400 nm.² The transmission properties of most IOLs in current use are still not comparable to those of the human crystalline lens. The human lens yellows with age, thereby attenuating blue light, while IOLs tend to be colorless.^3-8

Blue light has been identified as a possible contributor to age-related macular degeneration (AMD). In 1992, the Chesapeake Bay Watermen Study⁹ identified a significant positive correlation between blue or visible light exposure and advanced AMD during the 20 years preceding the . . .
