I have been on a 1/2 dose of tamoxifen for about 4 weeks. My doc started me on a smaller dose due to my intractable migraine headaches. I noticed today that my vision is more blurry than normal. Granted I have been using eye glasses for the first time in my life for about 6 months, but mostly just for reading with a very mild Rx for distance. Could the blurry vision be from tamoxifen or from just getting addicted to wearing these new glasses?
