About 7 months....started in late 2015...passed my CA DMV 10 year license renewal in June of 2016 without any difficulties and no glasses.
I can check exactly as have the ophthalmologist prescription for the Cataract procedure...went to an informative class and got some bottles of eye drops to prepare for the op...right eye was worse.
A few days before my test I went to the DMV and checked that I could read all the distance eye test cards....OK...and the bonus was they all had the same letters but in a different order....Recall the scene in Space Cowboys.
Now I have the same problem with the left eye....will report back later
