Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] refer to Figure 1 to Figure 5 , a kind of dura mater pressing prism, comprises optical surface microstructure, assembly convex groove, material base and dura protective layer, and described material base adopts the base of PMMA polymer material, and the light transmittance of described PMMA polymer material reaches 99%, the upper surface of the material substrate is an optical surface microstructure, and the optical surface microstructure adopts a Fresnel optical microstructure, and the assembly convex groove surrounds the periphery of the optical surface microstructure, and the material substrate The bottom surface is a hard film protective layer.

[0029] Further, the fitting convex groove is a circular V-shaped convex groove. Of course, other shapes are also possible.

[0030] Still further, the hard coat protective layer is a protective layer obtained by...

Abstract

An epidural press-on prism comprises an optical surface microstructure, assembling protruding grooves, a material substrate and an epidural protecting layer. The material substrate is a substrate made of a PMMA polymeric material. The light transmittance of the PMMA polymeric material reaches 99%. The upper surface of the material substrate is the optical surface microstructure which adopts a Fresnel optical microstructure. The assembling protruding grooves are arranged around the optical surface microstructure in an encircling way. The bottom of the material substrate is the epidural protecting layer. The invention further provides an epidural press-on prism assembling method. The prism with relatively good capabilities of resisting external pollution has the characteristics of simplified technical process and relatively low assembling difficulties.

Description

technical field [0001] The invention relates to a microstructure optical device and an assembly method thereof, which are suitable for the fields of strabismus correction and strabismus treatment 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. At present, domestic medical institutions mainly have four methods for the treatment of strabismus: 1) wearing pinhole glasses; 2) strabismus therapeutic apparatus; 3) wearing glass prism glasses; 4) ophthalmic surgery. Among them, pinhole glasses and strabismus treatment devices are suitable for the auxiliary treatment of mild strabismus; glass prism glasses have thick lenses, and the general corrected diopter is less than 6...
