Reasonable approach, just not something that I've ever heard before, as the sun generally affects the front of the eye!
Still, good luck!
Even still, our eyes are more sensitive than that of a person without Diabetes and Cataracts are problems for people with Diabetes. Like I said I have really good controll, but I read somewhere that after having Diabetes for 20 years, 60% of people with Diabetes have some sort of eye problems so thought I should start wearing them even if it only helps a tiny bit. I'm up to 13 years this year (got it when I was 6).
Diabetes isn't that bad as long as we control it, but I love it when I read something and look at the people at risk and I always seem to find Diabetes in there, lol.
Thanks, I have confidence that I can convince them, ahah.
