I wear prescription glasses, and I don't have contact lenses and neither do I have sunglasses (they won't fit, or would need to have force too)
Thing is, if riding during the day (which is rare since I commute in the morning and come back early evening) I sometimes can hardly see anything. At some point, near 11h30, I have one eye closed and the other half-closed urg.
Is there such a thing as a cap that goes under the helmet? and doesn't heat you up like crazy..?
