well if you have glasses the ones that would be a good investment
would be Oakley Goggles and SCOTT goggles........
they have sets of goggles made so you can wear Glasses under them.
there pricing are around 34.00 to 120.00 depending on "Style"
like the Oakley MX L-Frame can wear glasses under them
and run about 30.00 to 35.00
or can get "Style'in" and go with the Oakley "Wind-Jackets"
those and the M-Frames are what i use.
but there kinda Pricey......
