ABSTRACT:
A pair of windshield eyeglasses (101) comprises: lenses (106) and a frame (102) for holding the lenses. Each of the lenses or the frame includes an edge formed with a windshield (107) for sealing a gap between the edge and a face of a user. The windshield extends from the edge and ranges from laterally inward side of the face to an upper intermediate portion and to a lower intermediate portion of the frame.By providing the windshield, the airflow along the user's face is changed to flow along the outside of the windshield. Therefore, the airflow along the face is prevented from entering between the eyeglass inner surface and the user's face. In particular, the airflow is effectively prevented from affecting the eyes from medial angles of eyes toward lateral angles of eyes. This eliminates interference with the natural flow of tears on the eye surface, making it possible to effectively prevent drying and inflammation in the eyes, or prevent foreign materials from coming into the eyes.
