Blocking the blue

摘要

Recent research surrounding the development of a blue blocking intraocular lens (IOL) for cataract surgery has again raised the question of the potentially harmful effects of light on the retina, particularly the blue light hazard. Does the literature support the hypothesis that blue light exposure contributes to the development of retinal damage, particularly macular degeneration? And, if we are developing blue blocking IOLs to reduce this risk, should regulators consider mandating the use of blue blocking filters in diagnostic equipment (slit lamps, direct and indirect ophthalmoscopes, ophthalmic cameras, and magnifying lenses) as well?
