Like jjjnettie, glasses on, glasses off, glasses on, glasses off...
Short sighted, no idea if I have any astigmatism or not (whatever astigmatism is!). Drives me troppo, trying to put glasses on upside-down in the dark, trying to thread the frames under a beanie using only one hand, apologising to 'normal' people for the focus, etc etc.
But hey, I can see, can't be too bad...
