I haven't read through the other replies, but hopefully allergy eye drops work for your daughter! It's a common symptom this time of year. I know they don't work for everyone, but worth a try if she hasn't already looked into it!
I had an appointment yesterday, but had to reschedule to next week due to unexpected travel. I usually go in every 1-2 years. Our insurance plan only covers glasses/contacts every two years. Throughout my life, I've always had very good vision (20/10), but with age, my reading vision has plummeted. I really struggle with having to constantly manage having glasses since I was so blessed for most of my life. Becuase it's just my reading vision, there is no surgery (other than getting your lenses replaced, akin to cataract surgery -- which is more invasive (and not covered by insurance) than I want to pursue, given that I don't have cataracts.
