Cataracts aren’t about age. They happen when the lens loses energy and the water inside it loses structure. Getting real sunlight, eating for metabolism, and avoiding stress and fake blue rich light keeps your eyes clear and alive.
I’ve improved my own eyesight and my wife’s by following these principles. Mainstream medicine would probably give other explanations or just dismiss it altogether.
There's no evidence that "fake blue rich light" at normal exposure levels has any effect, and not for lack of investigation. Ironically, "real sunlight" which you highlight as a benefit is actually a risk factor, given that UV-B and UV-A damage the lens - which is why sunglasses are recommended.
I'd highlight that much of the publicly-perceived "dangers" of blue light are, at best, exaggerations of weak evidence by lens manufacturers who want to upsell blue light blocking spectacles or IOLs. It's not like there's some big medical conspiracy to keep the dangers of normal levels of blue light a secret - the medical manufacturers would love for it to be true so they could sell you more products.
