Embodiment Construction

[0025] The present invention will be described in further detail below by means of specific embodiments:

[0026] The reference signs in the drawings of the description include: lens mechanism 1, visual mark 2, light mixing plate 21, light-transmitting mark 22, color light source 23, track 3, pulley set 4, belt 41, pulley 42, motor 5, central control Institution 6.

[0027] The embodiment is basically as attached figure 1 And attached figure 2 Shown:

[0028] The visual chromatic aberration screening instrument includes a lens mechanism 1, an optotype 2, a track 3 and a translation mechanism. The lens mechanism 1 is equipped with a convex lens or a concave lens, which are respectively suitable for myopia and hyperopia patients. The lens mechanism 1 and the track 3 are arranged in parallel , the visual target 2 is slidably connected on the track 3 and distributed in the coaxial direction with the perspective mechanism, the visual target 2 is connected with the translation m...

Abstract

The invention relates to the technical field of eye exercise physiotherapy devices, in particular to a vision color difference screening instrument which comprises a lens mechanism, a sighting mark, a track and a translation mechanism. The lens mechanism is provided with a convex lens and a concave lens, the lens mechanism and the track are parallelly arranged, the sighting mark is slidably connected to the track, and the sighting mark and a perspective mechanism are coaxially distributed. The sighting mark and the translation mechanism are connected to be used for movement of the sighting mark. The vision color difference screening instrument further comprises a center control mechanism. The sighting mark comprises a color light source and a perspective mark which adhere to each other. The center control mechanism is electrically connected with the color light source to be used for controlling color change of the color light source. The center control mechanism is further electrically connected with the translation mechanism to be used for controlling the sighting mark to move. Through detection and judgment by human eyes, an optimal matching color and an optimal range suitable for users are screened, visual recovery can be performed under the most appropriate color light conditions, and the vision color difference screening instrument has a certain assistance effect on the user's visual recovery.

Description

technical field [0001] The invention relates to the technical field of eye exercise physical therapy devices. Background technique [0002] Common vision problems include nearsightedness, hyperopia, astigmatism, strabismus, amblyopia and presbyopia, etc. At present, the methods to solve these problems are generally to wear glasses or surgical treatment, but as we all know, glasses can only correct the habit of eyes to see things, not To cure these diseases, the current method that can really cure myopia is surgery, but surgery has certain risks, especially for the young people whose eyes are still in the stage of development. [0003] In order to overcome these problems, a series of treatment methods and equipment such as fog vision method are produced. Chinese patent CN101773443A discloses a device for visual function optimization rehabilitation training. The invention includes a support frame, a working frame, a special inspection disc, a video screen, a video screen gui...
