Novel same vision machine
Technical Field
The utility model relates to the field of cameras, in particular to a novel camera.
Background
The children's vision problem always is a focus of social attention, intermittent external strabismus is a transitional strabismus between external strabismus and constant external strabismus, the prevalence rate is high at the first place of various commonalities external strabismus, the onset age is early, and the children's vision problem is the most common external strabismus type, but the related research at home and abroad is concentrated on the effect of operation and postoperative training. Under physiological conditions, vision of both eyes is classified into three-level functions, i.e., simultaneous vision function (level i), fusion vision function (level ii) and stereoscopic vision function (level iii).
There are many clinically applied instrument methods for binocular vision function examination, and studies indicate that the fusion range of the homovision examination in various methods has the highest sensitivity to binocular vision function abnormality of patients with intermittent external strabismus found in early stages. The main structure of the common vision machine in the prior art is two lens barrels, and each lens barrel is internally provided with a plane reflecting mirror which forms an angle of 45 degrees with the sight line, so that the two lens barrels can be respectively bent to the left and right directions by 90 degrees.
