The utility model provides an AR diffraction optical waveguide lens and a near-to-eye display device comprising the AR diffraction optical waveguide lens. The AR diffraction optical waveguide lens comprises a vision correction lens with diopter; and a diffractive optical waveguide bonded, glued or embedded in the vision correction lens. The AR diffraction optical waveguide lens designed by the utility model has a vision correction function, and has the advantage of being light and thin compared with the traditional AR glasses with externally-hung myopic lenses; a user with visual impairment can use the AR glasses adopting the AR diffraction optical waveguide lenses as vision correction glasses for a long time. 本实用新型提供一种AR衍射光波导镜片和包括该AR衍射光波导镜片的近眼显示设备。所述AR衍射光波导镜片包括：视力矫正镜片，具有屈光度；和衍射光波导，键合、胶合或嵌入所述视力矫正镜片。本实用新型设计的AR衍射光波导镜片兼具视力矫正功能，其相对传统外挂近视镜片的AR眼镜方案具备轻薄优势，此外由于衍射光波导直接和视力矫正镜片键合、胶合或嵌入其中，视力缺陷用户可将采用AR衍射光波导镜片的AR眼镜当做视力矫正眼镜长期使用。
