Computer glasses

My computer glasses look like this but green

I've got new glasses. When I went in, the eye doctor said they now make something called computer glasses, optimized for 16-18" away, the distance of a screen.

She showed me through lenses what it would look like. I was hooked. Now I have regular glasses and computer ones.

I can map my days by the glasses. If I've mostly worn the computer ones, it's been a sedentary day. If I've mostly worn regular ones, I've been active.
