I just had cataract surgery, to improve my vision. Decades ago I read in PF Reporter or Electronic Servicing Magazine about the horrors of needing trifocals glasses.
If there is a thread of this, poke me there.
I learned that one should research a lot before going for surgery, good and bad. I read this forum as my favorite past-time, wish I had asked here first.
For fun stuff, I wanted to document color changes between eyes like color perception, and use GIMP to make my new eye vs old eye color rendition the same on the monitor., it was huge, now brain is making them the same.
Some facts: I have a borg type moving cat's reflection out of my eye to friends which freak out most users, but i will find it fun.
Anyway it is late, will pursue tomorrow.
