Hello. Welcome to PC. You could get a second opinion to fortify the first that includes a full eye exam but I seriously doubt you are going blind and I don't know of anybody going suddenly blind. When you start worrying about it you could picture a huge stop sign and say aloud...STOP...don't go there...that's false.

I'm sorry you're going through this anxiety. I hope you feel better about this soon. Sending big hugs.
