PROBLEM TO BE SOLVED: To provide a pair of protective glasses capable of perfectly protecting eyes by effectively absorbing and reducing an impact by a collision with a flying object such as ball, person, object or the like as well as capable of preventing the protective glasses from displacing from a face of a wearer by preventing deformation (twist) at the collision.SOLUTION: The protective glasses is constituted of a hard front frame 1 and a soft rear frame 2 which are integrated with each other. The rear frame 2 is configured to have a periphery which comes in close contact with a face of a wearer. The rear frame 2 is constituted of an elastic deformation part 5 extending from both sides of the front frame 1. The elastic deformation part 5 is constituted of a front deformation part 9 and a rear deformation part 10 which are separated from each other via a vertical bore Ha. Further, the rear deformation part 10 is constituted of an upper rod 10a and a lower rod 10b which are separated from each other via a lateral borehole Hb.SELECTED DRAWING: Figure 1【課題】ボールなどの飛来物や対人、対物衝突による衝撃をより効果的に吸収、緩和し、眼をより完全に保護することができ、衝突時の変形(ねじれ)を抑制し、着用者の顔からのズレを防止することができる保護眼鏡を提供する。【解決手段】硬質の前フレーム1と軟質の後フレーム2を一体化させてなるものとしており、後フレーム2の周囲を着用者の顔面に密着するようにしており、後フレーム2を前フレーム1の両端から延設させ弾性変形部5とし、弾性変形部5は、縦抜孔Haを介して前側変形部9と後側変形部10に分離させたものとし、さらに後側変形部10は、横抜孔Hbを介して上杆部10aと下杆部10bに分離させたものとしている。【選択図】図1
