Polarized Lenses

I wear a pair of el cheapo sunglasses which are really comfortable and
seem as good as ones costing ten times as much.

I have just bought a Cateye Astrale but can't read the display when
wearing my sunglasses because of their polarizing filters.

I guess there's no solution other than a new pair of glasses?

Incidently, here in Australia, when I'm not cycling I spend a lot of
time near the sea or by the pool - yes even in winter :-), and that's
why all my sunglasses have polarizing lenses.

hmm  maybe while riding, rotate your head 90 degrees to
  read the display?

There are even more compelling reasons to not use polarizing glasses
when bicycling than not being able to read an LCD display, and that is
wet roads.  In the wet, you cannot tell wet from dry because
reflections from a wet road are strongly polarized such that,
depending on the direction of the sun, wet pavement looks dry and dry
looks wet in comparison.

There's no doubt what's wet in that case.

I guess Jobst doesn't ride much in with a sunny morning
  after a rainstorm. Sometimes a wet road reflecting light
 can just about blind you without polarized glasses.
Then again in the Seattle area for spring and fall, I ride
 most of the time assuming the road is wet or will be
 wet just around the next corner.

I ran into this problem with one of my customers who I sold an Astrale to.
I actually found him a computer which he could use his glasses with.  I
think it was an Avocet.  You could try looking at different brands with your
glasses on, and you will find one which works.

Rotate the display 90 degrees (OK, you'll have to read it sideways), or
else twist your head 90 degrees (similar).
