Abstract

The invention provides a strabismus angle measurement device with a hard film pressing triple prism. The strabismus angle measurement device with the hard film pressing triple prism comprises a strabismus angle measurement bar and the hard film pressing triple prism. The hard film pressing triple prism comprises an optical surface microstructure, an assembly groove, a material base and a hard film protective layer, wherein the material base is made of a PMMA polymer material, the light transmittance of the PMMA polymer material reaches 99%, the optical surface microstructure is arranged on the upper surface of the material base, the optical surface microstructure is a Fresnel optical microstructure, the assembly groove surrounds the optical surface microstructure, and the hard film protective layer is arranged on the bottom surface of the material base. The strabismus angle measurement bar comprises a handle and hard film pressing triple prism assembly holes, wherein the handle is located at the end of the strabismus angle measurement bar, supporting rings used for supporting the hard film pressing triple prism are arranged in the hard film pressing triple prism assembly holes, and the hard film protective layer of the hard film pressing triple prism is located on the supporting rings. The strabismus angle measurement device with the hard film pressing triple prism can achieve non-contact measurement and is good in measurement effect.

Description

technical field [0001] The invention relates to a strabismus measuring device, which is suitable for the fields of strabismus testing and strabismus screening in ophthalmology. Background technique [0002] Strabismus is a common eye disorder in children. Literature survey found that the prevalence of strabismus in children worldwide exceeds 2%. Strabismus not only affects the appearance of the child, but also seriously hinders the child's visual development, and even affects the child's physical and mental health. In recent years, with the development of material science and the progress of material manufacturing technology, press-fit prisms have begun to be used in the auxiliary treatment of children's strabismus. It consists of a group of Fresnel microstructure prisms neatly arranged to control the refraction of incident light. Reports from medical institutions show that press-fit prisms have achieved good clinical therapeutic effects in adjuvant treatments such as imp...
