While the study did not directly link cataract surgery to a lessened dementia risk, researchers hypothesize that the lower risk may be associated with higher quality sensory input from the eyes to the brain after cataract surgery. 

Lee said those who have their cataracts removed are also getting more blue light.

“Some special cells in the retina are associated with cognition and regulate sleep cycles, and these cells respond well to blue light,” Lee said. “Cataracts specifically block blue light, and cataract surgery could reactivate those cells.“

还有这种好事？也算是因祸得福了。
