Abstract

The invention discloses wearable glasses with variable prism degrees, wherein a patient directly wears the glasses which can be inserted into different prisms to perform free space visual training, and performs a binocular fundus outward training set and fundus inward training divergence. The key points of the technical scheme are as follows: the prism lens comprises a lens frame, two lens frames and prism lenses of various specifications, wherein a first lens groove used for being embedded into common lenses is formed in the lens frame, a second lens groove used for horizontally placing the prism lenses is formed in the outer side of the lens frame, a positioning frame is arranged on the periphery of the prism lenses, and the positioning frame can be embedded into the second lens groove. The invention is not limited by space and instruments, the patient can wear the glasses to move freely to perform the visual training, the object image is displaced through the refraction effect of the prism, the human eye needs to actively gather or diverge to maintain the single vision of two eyes, the prism with different prism degrees is arranged in the frame, the training of wearing the prism requires the human eye to adapt and use the divergence or the convergence all the time, and a certain tension level is maintained, thereby achieving the continuous training effect.

Description

Wearable glasses with variable prism degree

Technical Field

The invention relates to the field of medical care products, in particular to wearable glasses with variable prism degree.

Background

The binocular vision function refers to a process that the eyes work coordinately, accurately and uniformly at the same time, light reflected by a certain object is imaged on corresponding areas of the retinas of the eyes to form two slightly different object images which are transmitted to the brain through a vision path, and the two slightly different object images are analyzed, integrated and processed in a cerebral cortex high center to form a complete impression with three-dimensional space depth.

Possible symptoms of visual dysfunction in both eyes are: the eye is swollen and headache when seeing near; the eyes are easy to fatigue and swell pain when being seen near for a long time, and the phenomenon of jumping appears when reading; far-looking translates into difficulty in focusing, ghost images of objects, etc. when looking near.

The visual function training is to generate certain cognitive load on visual systems (including adjustment, convergence, eyeball movement and the like) by methods of optics, psychophysics and the like, so that the adaptability of binocular vision is improved, and the aims of comfort and coordination of using the eyes are achieved, the conventional binocular visual function set divergence training is to use red and green glasses, polarization glasses or a clapboard method to conduct the set divergence training by binocular vision, and special graphic cards, picture plates and the like need to be watched actively during training, but the existing training mode has the following defects:

1. when training, a patient needs to be limited in a specific space, the body cannot move freely, discomfort is easy to occur, and the patient needs to frequently watch the chart card for a long time, so that eye muscle tension and glasses fatigue are caused, and the training effect is influenced.

2. The types of the chart cards for training are limited, and the conventional training equipment enables a patient to repeat specific actions for multiple times, so that the training is not flexible enough, and the optimal training effect cannot be achieved.

Disclosure of Invention

The present invention is directed to solve the above problems of the prior art, and an object of the present invention is to provide wearable glasses with variable prism, in which a patient performs free space visual training by directly wearing glasses that can be inserted into different prisms, and performs a binocular fundus outward training set and fundus inward training divergence.

In order to realize the purpose of the invention, the invention adopts the following technical scheme:

wearable variable prism degree glasses, including mirror holder, two picture frames and the prism piece of multiple specification, the inside first lens groove that is used for imbedding ordinary lens that is equipped with of picture frame, the picture frame outside is equipped with the second lens groove that is used for the level to place the prism piece, the prism piece periphery is equipped with positioning frame, positioning frame can imbed in the second lens groove.

Preferably, the upper edge and the lower edge of the positioning frame are straight edges, the second lens groove comprises an upper sub groove and a lower sub groove, the upper sub groove and the lower sub groove are parallel to each other, the notches of the upper sub groove and the lower sub groove are opposite, and the distance between the upper edge and the lower edge of the positioning frame is equal to the distance between the bottoms of the upper sub groove and the lower sub groove.

Preferably, a positioning structure is arranged between the positioning frame and the second lens groove.

Preferably, the first lens groove is equipped with a support frame for carrying a common lens, and the support frame and the positioning frame are both provided with handles.

Preferably, the prism sheet is a glass lens or a pressed prism sheet.

Preferably, the two mirror frames are connected in a relatively sliding manner, and the mirror frames are further provided with a fine adjustment mechanism for adjusting the distance between the two mirror frames.

Preferably, fine-tuning includes knob and lead screw, knob and lead screw tip fixed connection, and the outside edge of one of them picture frame is located to the knob, lead screw and the picture frame swivelling joint who keeps away from the knob, and the picture frame that is equipped with the knob is equipped with the internal thread and overlaps and establish on the lead screw.

Compared with the prior art, the wearable glasses with variable prism degree, which adopt the technical scheme, have the following beneficial effects:

firstly, the wearable glasses with variable prism degrees are not limited by space places and instruments, and a patient can wear the glasses to freely move to perform object vision training, so that the comfort level is improved.

Second, through the refraction effect of prism with the object image displacement, the people's eye just need initiatively do the set or diverge and maintain the monocular, through install the prism of different prism degrees in the mirror holder, wear the prism training and require the people's eye to go to adapt to all the time and use and diverge or set to maintain certain tension level, reach the training effect of persistence.

When the patient wears the glasses to conduct object vision training, different external objects can be freely selected to serve as target images, training is more flexible, two eyes can be trained to a greater degree, and training effects are improved.
