Abstract

The utility model discloses an eye functional training device which comprises a pedestal, a guide rail and a target, wherein the guide rail is arranged on the pedestal, and the target provided with identification patterns is arranged on the guide rail and moves along the guide rail in a front-and-back mode. At least one myopic mirror provided with two lenses is arranged on the front side, right facing the target, of the pedestal. The eye functional training device is characterized in that each two lenses is composed of a front convex lens and a rear concave lens or composed of the front convex lens and a rear convex lens. When the front convex lens and the rear concave lens are adopted, the focal length of the front convex lens away from the target is twice to eight times larger than the focal length of the rear concave lens close to the target. When the front convex lens and the rear convex lens are adopted, the focal length of the front convex lens away from the target is twice to eight times larger than the focal length of the rear convex lens close to the target. Compared with the prior art, the eye functional training device has the advantage of being capable of forcing myopic eyes to improve distance vision through telescopic training.

Description

A kind of eyes functional training device

Technical field:

This utility model relates to a kind of health-caring equipment, particularly a kind of eye health appliance.

Background technology:

Modern society, along with popularizing of electronic information technology, the information that people accept by vision is more and more abundanter, thereby the excessive use that causes eyes causes the organic variation of various eyestrain and visual system, wherein the most obvious example is because long-term mandatory quantity of looking the myopia crowd who closely causes increases and the trend that becomes younger.The motions such as modern medicine confirms by playing table tennis, shuttlecock, allow eyes follow the tracks of the spheroid of rapid movement in large scope, and the pressure eyes are looked motion far away, can temper the regulating power of eye muscle, alleviate the spasm of ciliary muscle, thereby the vision of improving prevents and alleviates myopia.But these motions need larger place, are difficult to chronically, take regular exercise everyday.

Have the eyes faculty training device of the eyes functional training carried out easily in smaller place now, as patent, CN201020176445.2 is disclosed, comprise lens mount, target, pedestal, target is arranged on the guide rail of pedestal, two groups of lens before and after being provided with on lens mount, by the combination that changes different dioptric front and back lens, make eyes see target clearly, then by the motion of target, train eyes.This training method, its essence is and help the patient to wear a pair of glasses, and then remove to watch target, thereby and the patient wears glasses at ordinary times and see the object of motion, without any essential distinction, so, be difficult to that eyes are carried out to substance and train.And, because complicated operation adds that optical system involves great expense, be difficult to the universal use in family.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of myopia of training to look the eyes functional training device that far improves the hypermetropia ability by pressure.

Eyes functional training of the present invention is to realize like this, movably target is set on the guide rail of pedestal, at least one nearly mirror of prestige that comprises two lens is set in the pedestal front that faces target, two lens consist of front convex lens and rear concavees lens or by front convex lens, rear convex lens forms, while adopting front convex lens and rear concavees lens, away from the focal distance ratio of the front convex lens of target near large 2-8 times of the focal length of the rear concavees lens of target, convex lens before adopting, during rear convex lens, away from the focal distance ratio of the front convex lens of target near large 2-8 times of the focal length of the rear convex lens of target, face and hope that nearly mirror moves forward and backward target, when hoping that nearly mirror is seen target, just can be in short-range scope, the simulation target is with large distance moving before and after the remote virtual image, trainer's eyes are able at a distance, large span focuses to train the regulating power of corresponding eyes.What while adopting front convex lens and rear concavees lens, see is the upright virtual image of target, and while adopting front convex lens, rear convex lens, what see is the virtual image of the handstand of target.

Here, between front convex lens and rear convex lens, Porro prism or roof prism are set.What see like this, is the upright virtual image of target.

The characteristics that the present invention is different according to trainee's distant vision, target leaves the solstics of lens can free setting, but the size of identification pattern is also adjustable, like this, target is when nearest from lens, the trainee can see identification pattern clearly, when target is positioned at the solstics of leaving lens, eyes can only see identification pattern clearly gruellingly or the pattern seen fuzzyyer.The remote setting that target is moved does not just see the position of the pattern on target the trainee, then, by mobile target from the near to the remote, training by a period of time, when target is positioned at the far point position of leaving lens, the trainee can low weight loose ground, while clearly seeing identification pattern, more again according to determining the position of far point with the adjusted principle or resetting the size of identification pattern.So, can look far by forcing eyes, with regard to the effect of the distant vision that can realize constantly improving eyes.

In order to keep trainer's attention, at the center of target, small size pattern is set, surrounding at target arranges the plural large size pattern that will be twice twice than the pattern at center, wherein, the figure of a large size pattern is identical with the figure of small size pattern, during training, need the trainer to judge small size pattern identical with the pattern of which large size.Like this, the attention that keeps the trainer by requiring the trainer to make a determination.

For the ease of changing pattern form and size, target is the liquid crystal display with player of remote-controlled operation.During use, by playing the incompatible replacing of enriching pattern of different pattern groups.

Eyes functional training device of the present utility model is to realize like this, comprise pedestal, be arranged on the guide rail on pedestal, be arranged on the target with identification pattern on guide rail and that move forward and backward along guide rail, at least one nearly mirror of prestige that comprises two lens is set in the pedestal front that faces target, two lens consist of front convex lens and rear concavees lens or by front convex lens, rear convex lens forms, while adopting front convex lens and rear concavees lens, away from the focal distance ratio of the front convex lens of target near large 2-8 times of the focal length of the rear concavees lens of target, convex lens before adopting, during rear convex lens, away from the focal distance ratio of the front convex lens of target near large 2-8 times of the focal length of the convex lens of target.During training, move target along guide rail, the trainer sees through the identification pattern of hoping on nearly sem observation target, be visible under the effect of amplification of nearly mirror, the displacement of target on guide rail is exaggerated 4-64 times, same, its translational speed also has been exaggerated 4-64 times, like this, just can the imitation table tennis ball or the rapid movement of shuttlecock, the virtual image of the target of the focal length tracking grand movement that the trainer just can be by the adjusting eyes like this realizes training the purpose of eyes.

Here, be provided with the power moving device of being controlled by control device that drives target on pedestal.During work, by control device, control the power moving device action, drive target and move forward and backward with speed, distance and the motion mode of setting.

Target is the liquid crystal display with player, and can remote manipulation.

This utility model is owing to adopt hoping nearly mirror, therefore, thereby has advantages of and can force myopia train the raising distant vision by hypermetropia.
