Vision correction glasses with horizontal double motor driving two eyes to slide by overlapping lenses respectively

Abstract

The invention relates to a pair of vision correction glasses with a horizontal double motor driving two eyes to slide by overlapping lenses respectively, and belongs to a device for electrically driving four parallel optical lenses to achieve sliding zoom vision correction. The device comprises a glasses shell, and a lens driving device, a controller, a power supply and the like which are arrangedin the glasses shell; two parallel convex bars are arranged on a lower baffle of the glasses shell, and a groove formed between two parallel convex bars is a lens clamping groove; the lens driving device comprises two decelerating motor assemblies fixed to L-shaped support plates at the two ends of the upper portion of a double hole strip-shaped plate, and four sliding lens assemblies are arranged in two strip-shaped holes of the double hole strip-shaped plate respectively; each decelerating motor drives the two overlapped lens assemblies to slide in opposite directions separately, and the two overlapped lenses generate a large amount of combined diopter. Therefore, by means of the eye zoom training device, a person suffering from myopia can be helped to recover eyesight.

Description

technical field [0001] The invention belongs to the technical field of zoom optical lenses, and in particular relates to a horizontal dual-motor driving device for driving two groups of parallel optical lenses with sliding zooming distances by electricity, which is used to slide the eyes of superimposed lenses for vision correction. Background technique [0002] Chinese patent 201610092191.8 "A Gradient Focus Lens" provides a lens with a flat bottom surface and a free-form surface on the other side, the free-form surface is composed of concave surfaces, and several regions are provided on the free-form surface, and each region are equal in vertical length. The length of the area is 0.1.0 mm to 100 mm, the diopters of the area are 1 to 2000 degrees, the diopters are evenly distributed on the lens, and the focal points are equally divided into each unit length. [0003] The defect of the above-mentioned "A Gradient Focus Lens" is that the "free-form surface" is used as a trai...

Problems solved by technology

The disadvantage is that one spectacles has only four arc rings with different curvatures, and the number of optional curvature mirrors for treating sick eyes is too small when wearing one such spectacles. It is very inconvenient to have spare glasses at home, which will affect the treatment; too many glasses for selection will increase the cost

[0007] (1) Unable to achieve the purpose of the invention: this patent only discloses the transmission mechanism, and does not disclose the structure of the "zoom lens", so it is not clear how the lens uses the transmission mechanism and how to achieve zooming. Spectacle lenses in 201310311306.4 "A New Orthokeratology Lens and Its Application Method", and 201521122053.7 "A Zoom Glasses" cannot realize the zoom application of "vision training";

[0008] (2) The transmission structure is wrong: the transmission order of the structure is motor-reduction gearbox-positive and negative screw-fixing bolt-front lens and rear lens slide in opposite directions

[0009] (3) The "fixing bolt" cannot realize the transmission: From the text and drawings of the patent document, it can be known that the "fixing bolt" is an intermediate component that transmits the "positive and negative screw" and the "lens", but the text and attached drawings of the patent document The figure does not provide the structure that the "fixing bolt" can drive the "positive and negative screw" and the "lens"

Only the positional relationship of each component, no structural relationship, can not achieve the transmission structure required to achieve the purpose of the invention
