Have you ever wished that your safety glasses were like your reading glasses. I've been wishing for a pair of these for a while now but didn't know that they existed.

I got my first pair of "reading" safety glasses almost 1 year ago. They cost me almost $30 at the time.

Still have a problem with them while going down stairs.
