After cataract surgery, the natural lens, which filters blue light, is replaced with a synthetic lens that allows more blue light to pass through. This sudden increase in blue light reaching the retina causes the brain to perceive a blue tint in vision. This effect is temporary as the brain and eyes gradually adapt to the new lens.
