Background technology

Eyes are that human body is set up the basic physiological function of visual organ to the three dimensions sensation with visual function.Sound eyes can remedy visual field blind spot defective with visual function, enlarge monocular visual field; Can form three-dimensional stereoscopic visual; Can accurately differentiate and look thing far and near distance, size, concavo-convex, height etc.Clinical ophthalmology functional amblyopia patient's eyes can't be set up visual organ to three-dimensional normal threshold of feeling with the visual function obstacle, and patient's study, work, life impacted, and can not be engaged in medical science, driving, work high above the ground, fine manipulation etc.Along with effective treatment to functional amblyopia, need set up the same visual function of eyes simultaneously, have only and set up eyes could be consolidated functional amblyopia effectively with visual function curative effect.Therefore, it is significant to treating functional amblyopia and consolidating the functional amblyopia curative effect with visual function to set up eyes, and at present, adopting synoptophore to carry out with visual function training to the amblyopia patient on the market is the medical procedure that realizes this purpose.But, carry out eyes with synoptophore equipment and can only on hospital clinical, carry out with visual function training, operate complicatedly, patient every day come and go hospital and cooperate difficulty, and the wasting of resources, clinical ophthalmology seldom adopts so far.

Summary of the invention

This utility model is a principle of utilizing binocular parallactic angle, and two width of cloth are had the complementary color collection of illustrative plates of parallactic angle value information, stimulates two eyes retina cone cells respectively.When watching an object point simultaneously attentively for two, can constitute a single binocular vision circle by two nodes and point of fixation, any point of dropping on the circle is mutual etc. to two folded angles, and the each point on the haplopia circle is all tied on two retinas with equidirectional and same distance and resembled.Right corresponding to the point on two nethike embranes of the round upward each point of haplopia, be corresponding retinal points.But, with point interior or in addition, all can not on corresponding point, tie and resemble at the haplopia circle.And the last knot of a certain distance that leaves corresponding point resembles, and for knot resembles lateral run-out, knot resembles the size of lateral run-out, is decided by the size of binocular parallactic angle.Knot resembles lateral run-out and has broken point-to-point geometrical correspondence, and two two dimensional images are merged through visual cortex, promptly forms three-dimensional depth perception, and it is the very important objective condition that obtains stereognosis that knot resembles lateral run-out.

This utility model stimulates the retina cone cell on the one hand by stimulating retina with the visual function training collection of illustrative plates, directly functional amblyopia is played therapeutic effect; Also be in the amblyopia treatment process on the other hand, cause neural impulse and be delivered to the maincenter visual cortex, melt the curative effect judgement that the picture back produces the 3 D stereo effect.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified.
