I Need Glasses

I took a walk without them just to [i]see[/i] what it was like. I'm surprised I didn't bump into anything or fall on my face. My eyesight has gotten pretty bad. I wear glasses all the time, though, so I hadn't really realized just [i]how[/i] bad. Some things might as well be invisible because I can't see them even when I squint; at least, not until I'm right about to smack my shin into it.
