Femara and double vision

Dana • My husband and I have been TTC for 4 years. Two with a specialist.
Has anyone had double vision and has been taking Femara/letrozole?
I started having it right after going to a new eye doctor and thought it was possibly because the prescription was a strength for contacts not as high as what I had been wearing the year before.
This year when I went, I went back to my original eye doctor because he was in network for our insurance coverage again and he said he didn't see any alignment problems. 
I have noticed when I get really emotional, hot or do things in a hurry it tends to trigger the double vision. 
Read something online and it got me to thinking that it might be medicine related rather than eye sight related. 
Was just curious if anyone else had had similar side effects.
