@arpie I had dry eyes when I started a month of letrozole (part of a trial) followed by chemotherapy 6 months ago. My optometrist had already recommended one set of drops - Thera tears - in individual vials. Now she’s suggested a couple of other drops for dry eyes including a manuka one. I always have a couple of vials in my pocket for when my eyes start to feel dry. I had started massaging my eyelids for pre-existing meibomiam gland dysfunction, but I’ve now an additional oil replacement drop - Nova tears to help with that.
Not having eyelashes means pollen and dust get in easier, so regular saline wash is a good idea, too.
sunglasses are very important to help protect eyes as is staying hydrated.
