Why Doesn't David Gordon Wear Glasses?

How well do you know the behind the scenes stories about Austrians? This is the first in an occasional series.

David Gordon, the philosopher and student of Austrian economics, who can often be spotted surrounded by the most attractive women in the libertarian/Austrian movement, likely spends a good portion of his day reading. He writes a weekly book review column for Mises.org, but you never see him wearing glasses. Why?

I'll post the answer, Monday.
