Don't be too distracted by the glasses thing, they have this machine with 40 yo on it and then they start handing out reading glasses when you turn 40-45.
The optician told me this, he said 'You'll be alright, you won't have to wear glasses to read the menu and all your friends will' - and I paled and went into a dead faint at the thought of being 45 and having dinner with friends in reading glasses and at the idea that I'd be so SAD and my life so uneventful that I'd actually feel smug about it. I couldn't get out of there quick enough. And I've never liked the LEANING thing they do, on their silly, whizzy stools.
I can't remember - have you been to a dermatologist?
