Sunglasses are usually a necessity for many fashionable men and women. But the most important function of a pair of sunglasses is eye protection. The eyes as the most vulnerable areas of the face require adequate protection from the dangerous UV rays in the sunlight. UV light is associated with a couple of health conditions including the eyes. In addition to skin cancer, UV rays are commonly referred to potentially cause cataracts and glaucoma. In this case, sunglasses protecting the eyes are quite necessary.
Sunglasses as UV protection tools are increasing popular nowadays. And with numerous options in local stores, online shops and the like, customers still need some useful words of caution when they buy sunglasses. Except for benefits of sunglasses such as UV protection and fashionable look, sunglasses are special devices on the face. As a result, one of the necessary requirements of sunglasses selection is to try on as many pairs as possible. Only in this way can a customer get a proper pair that suits personal traits.
For instance, sunglasses sitting on the nose must be comfortable. They should never pinch the bridges of the nose. In addition, sunglass rim also needs careful check-up. The rim may touch the eyelashes or sag down to one’s cheeks. All these conditions should be strictly avoided. Another critical requirement involves the center of the sunglasses. In a proper way, the pupil should be right in the center of a lens. Otherwise, the glasses are considered as imperfectly placed. This condition can harm one’s vision.
Similar to haircuts and makeup, sunglasses still need close consideration of a wearer’s face structure. A face shape in opposite to the sunglass frame shape is the best situation that this combination can give rise to an outstanding statement of the wearer’s face features. Basic face shapes include oval, round, angular, square, oblong, and heart-shaped and so forth.
