No, I've never had that with methotrexate.
But what you described sounded like dry eyes to me. Found this: https://www.ncbi.nlm.nih.gov/pubmed/7296473
Dunno how high "high dose" methotrexate is, but it does seem plausible that methotrexate could be the cause of your eye issues. But to get a more definite diagnosis, I would see an optometrist.
