Anastrozole and vision

Hi, I am 2 year out of chemo and nearly 2 years into hormone suppression.  I am taking Anastrozole and zoladex and zometa. 

I seem to be experiencing ongoing vision loss, I have had 4 glasses prescriptions in just over 2 years. Has anyone else experienced this and did it/does it effect your ability to drive? 

I am quite concerned about my vision now.

TIA

Becky
