Hi
I have been on various chemos for HER2 positive metastatic cancer for the last 3 years and I have had problems with my vision throughout. I did see an optometrist about 1/2 way through my taxol treatment and paid some serious money for "reading glasses" that I would also be able to use for TV watching and computer work as I was having trouble focusing on distance after reading. I found them to really not solve the problem on the bad days and I have since purchased a cheap pair of reading glasses from the chemist that work fine.
Perhaps you may want to wait until you are finished to see what happens.
Best of luck
