Below the further improvement to technique scheme:
The center of convex lens and the center of camera are point-blank.
Lens hanger comprises supporting plate, and described supporting plate is connected with contiguous block, and described contiguous block is provided with several back-up rings, between every two adjacent back-up rings, can hold myopia or hyperopic lens; The center of back-up ring and the center of convex lens are point-blank.
The end face of inner sleeve lid is rectangle, and described camera is arranged on the center of inner sleeve lid.
The cross section of described outer sleeve is rectangle.
In described lamp box, be provided with several LED lamps.
During use, open lamp box, inner sleeve is moved to normal eyeball image space, and by place the variation of different dioptric protruding, concace mirror lens simulation curvature of lens at lens hanger, utilization can push-and-pull inner sleeve, mobile imaging template, can find intuitively the imaging point of myopia, long sight, image is imaging point when template is clear, and myopia is imaged on the place ahead of template, long sight is imaged on the rear of template, thereby discloses the origin cause of formation of myopia, long sight.
By continuing to place contrary number of degrees lens on lens hanger, can simulate antidote, on inner sleeve lid 17, settle camera, experimental phenomena can be carried out to projection displaying.
Below in conjunction with accompanying drawing, the utility model is further described.
