Film-coated lens with refraction correcting function

Abstract

The invention provides a film-coated lens with a refraction correcting function and belongs to eyeglasses or an eyeglass lens. The film-coated lens comprises a lens and a coated film, wherein the lens is a plano lens (1); the coated film is a refraction coated film (2) made of flexible and transparent plastic; and one face of the refraction coated film (2) is a plane which is attached to the plano lens (1), and the other face of the refraction film (2) is at least provided with a concave circular surface or a convex circular surface. Two types of eyeglasses with different degrees can be formed by combining the coated film on front and back sides of the plano lens (1) so as to bring convenience to diopter adjustment and conveniently meet the visual requirement on frequent change of sight distances. The film-coated lens has the advantages of convenient use, rapid replacement, high comfortableness, capability of changing coated films with different diopters according to the position change of a student in a classroom and the demand of horizontal change of vision correction, simple structure, low manufacturing cost, remarkable refraction correcting effect and wide application prospect.

Description

technical field [0001] The present invention relates to spectacles or spectacle lenses, more particularly to a film lens with refractive correction function. Background technique [0002] At present, the commonly used hard refractive correction glasses are inflexible and difficult to meet the visual requirements of students looking at the blackboard and taking notes to constantly change the distance. [0003] China Patent Announcement No.: CN2916678, Announcement Date: June 27, 2007, the utility model name "A kind of glasses with releasable film" proposes that the lens is inlaid on the frame, and the releasable film is laminated with a transparent jelly technical solutions on lenses. Several layers of transparent films are pressed together with the lens, and an opening for easy film peeling is reserved on a corner of the lens. During use, if the surface of the lens is polluted and the vision is blurred, the transparent film can be peeled off from the opening reserved on th...
