Our current lifestyle exposes us to an abundance of blue light in our daily lives in the form of laptops, cell phones and tablets

Short wavelength/high energy blue light with an excitation peak around 440 nm, has a negative effect on retinal health as it leads to creation of free radical oxygen species which have a damaging effect on retinal cells, including the retinal pigmented epithelium (RPE) cells and photoreceptors

Experimental evidence suggests that blue light induces retinal toxicity and damage

Clinical studies support that there are no clinically meaningful differences between short term BCVA and functional vision between blue-light filtering (BLF) and non-BLF IOLs and that BLF IOLs do not interfere with circadian rhythms and mood

Clinical evidence shows that BLF IOLs reduced photostress recovery time and glare disability

Clinical studies have not definitively demonstrated a protective benefit of blue-light filtering lenses on macular health
