Embodiment Construction

[0004] The solution to the problem of the present invention is to design a planar convex lens type film that can be attached to the surface of the screen. The whole film is an incomplete spherical crown (the radius of the ball is 5 meters, and the radius can be changed according to the needs), and the bottom surface of the film is a flat rectangle (the size of the rectangle is the same as the size of the display screen, such as 14 inches, 21 inches, etc.). The four vertices are all on the spherical surface (in order to reduce the thickness of the film), the vertical projection of the film on the bottom surface completely falls on the bottom rectangle (the excess part is cut off), and the bottom surface of the film is painted with transparent glue.

[0005] After using the film, the light emitted from the screen converges after passing through the film (but the focus point is far behind the user), and then the converged light enters the human eye. At this time, the human eye can...

Abstract

A screen surface film for protecting eyes is prepared as setting said film to be planar lens structure being prepared from light transmission plastic material and making film body be incomplete spherical crown body with bottom surface being processed to be planar-rectangular form for releasing tense of musculi oculi.

Description

technical field [0001] The invention relates to a device which can prevent eye fatigue and myopia when people use computers for a long time or watch TV at a close distance. Background technique [0002] The current display screen itself does not have the function of protecting the user's eyes. Therefore, when people (people with normal eyes) use computers or watch TV at close range, if the eye muscles relax and the curvature of the lens is normal, the image on the screen will fall behind the retina, and a clear image cannot be obtained. Therefore, the human eye muscles need to contract to increase the curvature of the lens and shorten the focal length of the lens so that the image on the screen falls on the retina to obtain a clear image. However, if this state continues for a long time, it will cause people's visual fatigue or myopia. Contents of the invention [0003] In order to make up for the deficiencies of current displays, the present invention provides an eye-pr...
