Is it possible to wear my prescription glasses over a non-prescription lens? I don't have enough money to buy prescription lens, much less an red lens. But without my glasses I'm blind as a bat and can hardy see the faces of people 20 feet away.
One time at the con I took off my glasses for about 10 min and somehow I had accidentally mistaken a popular cosplayer group with another right in front of their faces. I was so embarrassed and I don't want to walk around without my glasses at a convention ever again!
What should I do, get prescription lens or just keep removing my glasses in-n-out during a convention?
