I had extreme pain and depression on all the aromatase drugs and was unable to take them for any length of time so I can't address those questions BUT, I do have a thought about your eye problem. For the past 10 years I have had 'dry eye'. It started during perimenopause and continues today (although not as bad). I believe dry eye can be a result of lowered estrogen in the body and hormonal changes. I use prescription eye drops that help my eyes retain and make more tears (there are two, Restassis and Xiidra). They have helped me immensely with this problem which isn't noticeable now, as long as I keep up with my meds. Perhaps a trip to your eye doctor for a 'dry eye' evaluation?
