Well, looks like you are planning for an outdoor activity. Generally speaking, when people are preparing to go outsde. What they should consider the most for their vision is strong sun beams, which sometimes are able to cause damage to our eyes. So, the function of your future sunglasse would be anti- sunlight, right? So, when choosing what you care for, you should ask for their utility and
see if they really serve to fight aganst sunlight. Basically, that will be ok. As to the appearance and design, they are just secondary.
If you regard the driving as your outdoor recreation on weekends, you'd better choose a pair of polarized eyeglasses which may help you see clearly and get rid of the strong lights. If you go fishing as your outdoor recreation, the polarized eyeglasses will also be a good choice to help you eliminate the dizzy lights reflected from the water. In addition, you can also choose the sunglasses for the outdoor recreation.
