Oh but you know how I help my vision when it starts declining now and then? Eat fish oil, very pure no mercury, eat it, six softgels a day and your vision will improve. Eyes are almost pure omega-3 omega-6 and omega-9 fats, in the lens and retina. Declining vision is basically due to your body rearranging its unsaturated fat reserves, with which it is endowed at birth and never gets more of. Some people their ears start to go, others their mind start to go (and that's why I was prescribed fish oil by a psychiatrist, but like one a day get real doctors need to up the dose), other people their joints or their heart. You can't just eat fish, the mercury completely undoes the effect. It's not found in nature. Only in labs. It's the fat endowment.
And that's the framework for compensating for blindness: not being blind in the first place. Undoing it. Dude you can eat 15 softgels a day.
My favorite is UP, Ultra Pure brand, but I can't find it outside Chile. In US, Nature's Bounty, just anything with very low amounts of mercury cadmium and pcb's.
So. Do you have a brand of fish oil we all can look into and research?
Also, there's this 2018 NIH study that says fish oil is no better than a placebo for dry eyes: https://www.nih.gov/news-events/news-releases/omega-3s-fish-...
