Blue light–blocking intraocular lenses (IOLs) trade off rod-mediated visual function for limited protection against acute retinal phototoxicity.1 Twenty-five years ago, I cautioned ophthalmologists and manufacturers that clear IOLs transmitted potentially harmful 330- to 400-nm UV radiation (UVR) to the retina.2,3 Within a few years, most manufacturers incorporated UVR-blocking chromophores into IOLs.4 Eighteen years ago, I suggested blocking violet light in addition to UVR.4 Violet light has substantial potential retinal phototoxicity but little effect on scotopic (nighttime) or photopic (daytime) vision.5- 7 Nonetheless, visible light–blocking IOLs have been introduced only recently in the United States.
