Alright old guys, from another old guy, I'm gonna share something that may help all your eyes out. I had PRK done to my eyes around 2016 (I think, give or take a year) and two years ago I started to notice it degrading. Harder to read signs down the road... focusing close to far took a while along with a lot of blinking, etc... then, as I do, I go down rabbit holes and found that a good quality vitamin E should help improve and retain vision. Basically, I guess our eyeballs lose that flexibility and it's an even bigger problem with all the seed oil shit in everything now.
It took a few months of doing vitamin E every day (I'll look up the amount) and now I don't have those issues nearly as bad. It's been just over a year of really hitting the E hard. If I miss a day or two I notice... so I stay on it for the most part.
Hopefully it will help some of you other old farts.
