I have the same experience to feel itch when i wear glasses. There are main two reasons leading to this situation. First of all, for the judgment of eye itching, if it is not accompanied by other symptoms, such as there is no discharge, no conjunctival irritation, etc, you can consider it as seasonal itch, which is quite normal and will remove a few days later. At the same time, this seasonal itch may accompanied with symptoms of nasal itching, runny nose, sneezing. The other reason is the degree of your glasses don't match your eyes. It can cause a lot of uncomfortable feeling, which including itchy eyes. Just give your eyes some time to adjust it or change a right one instead. It's not a big deal, don't worry.
