Two through-holes and a slit extending therebetween are provided in each of bilaterally symmetric locations near a top edge of left and right sides of an eye shield sheet made of transparent resin sheet. The eye shield sheet is obtained by forming an elastic rod into an approximate U-shape securable to the head of a wearer, and includes a curved section at each temple region of the wearer that curves inward to fit into the slit and the two through-holes. Attachment of the sheet to the frame is completed by the wearer first bending the entire sheet and positioning the sheet on the inner side of the frame, and then inserting the curved sections of the frame one side at a time into the sheet simply by pressing the curved section against the slit to open the slit and continue pressing until the frame fits into the two through-holes.
