Living in Florida, that afternoon sun can be too much. I'm 72. Coping with cataracts as well it just makes things worse. Mine are ready to remove, but my MD may be a problem. Just told by my optometrist my MD has gotten slightly worse so going to the opthamologist to have that addressed as well. Problem I have to wait until late August - first available appointment while our docs are trying to catch up after being shut down for 2 months. At this point my vision has just gotten worse from the cataracts. No MD blind spots thank God.
