I have a pair of Oakley Flak Jacket, and it is really comfortable to wear. It fully covered my eyes from all angles and you don't need to worry something running into your eyes when cycling. It is also polarized and keep out the sun a noticeably large amount compared to my other sunglasses.
Oakley is an famous brand for carrying sports sunglasses. So, i believe it is a good choices for buying oakley cycling glasses. Commonly, Oakley cycling glasses have a cool designs with colored lenses and frames. Besides, most of their cycling glasses are made of polarized lenses that make the glasses not only protect the eyes from UV rays in sun, prevent wind and debrs in the air, but also filter glares thus to give you the best clear and comfortable vision.
