PURPOSE:To allow a user of normal spectacles to wear protection spectacles in combination by fringing correcting lenses of correcting spectacles with elastic bodies, etc., in close contact, and preventing water from flowing inside or outside of the protection spectacles. CONSTITUTION:The circumference of the correcting lens 4 is held hermetically with a waterproof packing 6 when necessary. Then, the lens inside 7 is fringed, clamped, and made hermetic with a correcting lens fixture 1 so as to prevent water, etc., from flowing in, and the united body of the correcting lens fixture 1, correcting lens 4, waterproof packing 6, etc., is united in one body with the protection spectacles 5 by being brought into press contact with the protection spectacles 5 like suction rubber. Further, the correcting lens fixture 1, correcting lens 4, waterproof packing 6, etc., are adhered fixedly with an adhesive 3 for reinforcing the fixation and further a waterproofing agent 2 for improving the watertightness, or fitted to the protection spectacles in one body upon occasion. |
