Interesting. I need to try those.
I am trying multi-focal contact lenses which worked for a few weeks but now I need my reading glasses again. I have to call the eye doctor and let them know. The way he explained it was the left eye was at +2.50 power reader and the right eye was +1.25 reader. While it lasted it was great. I'm wondering if the power of each lease will have to be increased? I don't know. Where can I get some eyeballs from a 20 year old installed in my skull?
