I definitely agree with you to never take yourself off any med - to contact your doctor to discuss any changes in sight or hearing. With that said, not one doctor, my primary care doctor who diagnosed me after a sputum culture, or my pulmonologist he referred me to, ever mentioned having a hearing or vision baseline because the meds could affect them. We have regular vision checkups and our eye doctor knew which one when he asked if on any new meds. My sight has been affected slightly - now 30/20 corrected still good but my hearing has taken a hard hit. As individuals what affects one may not affect others and that is why it is important to get baselines with regular checkups.
