Contacts? Don’t you need to see for them to help

Some “blind” people do have data coming in, it’s just so blurry/skewed that it’s worthless. It might be possible to fix this but it would be a case by case basis and likely very expensive. Not all blindness is a world of black

Even totally blind people can usually detect light as painful, slightly less dark darkness. That's actually why so many wear dark sunglasses
