Thanks for the replies. I don't take any allergy meds because since my cats died and I moved away from Arizona, I haven't had any environmental allergies at all. My eyes weren't even itchy - just terribly burning-dry and sore, especially at night.
It's the first time I've been free of environmental allergies for as long as I can remember, which is why I disregarded my eye-doc's comment that my eye dryness is caused by allergies. The only daily med I take is Omaprozole.
What you both say is logical, which is why I'm mystified. If I have dry-eyes, for whatever reason, and not allergic conjunctivitis, then why do the dry-eye drops give no relief at all - and yet the allergy drops have solved the problem?
