If you can't find them in your nearby store, you can try to search them online. There are many online optical stores offering wrap around sunglasses for women in quite cheap price. You can try this link: http://www.firmoo.com/wrap-around-rx-sunglasses.html If you are nearsighted, you can also make it prescription sunglasses but it is not suitable for people with strong prescription.
You can get such kind of sunglasses both in solid shops and online stores. Personally speaking, I prefer to buy glasses online because there are more discount and styles in online stores. There are even free glasses available for new customers in Firmoo.com and coast.com. You may have a try. Wrap around sunglasses are quite fashionable, can provide you full eye protection, make your face look smaller and hide your dark circles. They are really a wonderful choice.
