Another reason to wear cycling glasses

Trevor Barton said:

You have to be careful with cycling glasses, though.
They can increase the risk of eye injury if they shatter
in an accident. Statistically, they have a negligable
effect on injury rates, the slight increase in eye
injuries is compensated for in whole population studies
by the slight decrease in overall mortality bought about
by people taking up cycling because they think they look
cool in them.

It just goes to show that anecdotal individual evidence
does not neccessarily reflect to statistical benifits. You
can't use a single incidence of cycling-glasses related
evidence to draw conclusions abount their overall
efficacy.

Of course, they won't help in a collision with a cement
mixer, unless they are peril-sensitive in which case they
will instantly go black and you'll never be entirely sure
what hit you.

Nice analogy. Seriously, they've been made out of
shatterproof plastic since Bernard Hinault crashed wearing
his glass shades and bled all over the finish line of a TdF
stage (it wasn't serious, but might have been).
