My prescription sunglasses were too expensive for the quality and rubbish.
The photosensitive type glasses are no good for sport.
Contact lenses + Prescription sunglasses = win, you get to choose whatever sunglasses you want and you also get contact lenses, which aren't that expensive nowadays, I use focus dailys but wear glasses most of the time, only where contact lenses when doing climbing or other physical activities, or occasionally on nights out, meaning a box lasts me a while, even wearing them everyday a months worth is only £20.
