This will raise the ire of many here but I would not recommend buying anything expensive because they all use plastic lens and plastic lenses scratch no matter how much you spent for the glasses or how well you try to treat them. The lowest costing glass with excellent vision acuity is the Tifosi line of glasses. This plastic lens crap kind of pisses me off because I use to be able to get a laminated lens, but because everyone has become weight weenies I haven't been able to find these anymore; funny, we all use to race on these "heavy" glasses and never thought anything about it and I still don't today being 63 years old my nose is still strong enough to hold a "heavy" pair of glasses.
