I'm dealing with nearsightedness, where distant objects are blurry, and had to get glasses.  Do you have any experience
Yes I've had glasses my whole life as my vision isn't so great. Do you need any advice?
Did you ever have headaches or eye strain?
Fortunately not really, maybe if I was reading a book with small font for a long time, but otherwise no issues.
I was shocked to learn that it increases my risk of cataracts and glaucoma, I just thought I needed glasses and that would be it.
Oh no you wouldn't want either of those, some people I know use marijuana to help their glaucoma.
Well, I found out that there is a bit of evidence that you can prevent it by having young children spend more time outside, but I lived outside as a child!
I had no idea there was a connection there. Do you mean you can prevent nearsightedness or glaucoma?
Nearsightedness.  They say it may prevent it because of the natural light exposure the young child would get by being outside.
