I was going to fail my next drivers test, with the best glasses I could get, I had bad cataracts. It cost me $3,000, but I got my vision corrected and my astigmatism. So, I don't need glasses anymore to drive and my reading vision is better, I can read a newspaper if I hold it an arms length away from me. I could not do that before. I needed a cross between my regular lenz and reading lenz before to see my computer good. Now I don't need glasses at all to put up bad posts.

Yes, the science has really improved with eyes.
