A good rule of thumb to follow when choosing sunglasses is to go for the frame that is the opposite from your face. It’s okay to experiment with several different types of frames before making your choice. You can also purchase different types of frames, as long as they look good on your face. While making your decisions, however, remember that the main purpose of sunglasses is to help protect your eyes, so be sure to choose carefully. Make sure they are a comfortable fit, and always keep in mind that they will serve you better while on your face than if they always remain in a purse or pocket.
