The invention provides a sighting target self-functionalized typoscope without limits on the size and azimuths of a sighting target for treating low-vision oculopathy. When people suffered from near sightedness watches words, shadows appear, the farther the place from which the words are watched, the thinner the word lines are and the more the shadows are; when the right eye is used for watching the word, the shadow appears on the left upper part of the word, when the left eye is used for watching the word, the shadow appears on the right upper part, and the phenomena of departing azimuths and irregular shapes also occur. The reason is as follows: when people suffered from near sightedness reads a book, the sight lines of two eyes are simultaneously placed on the same place, the head is usually lowered to a lower sight line to watch a position of a higher visual surface, thus, the effect of the sight line direction leads to the shadow and the azimuth of the word, and the effect is used for treating the near sightedness in the invention. In the sighting target self-functionalized typoscope provided by the invention, a sight hole is arranged at the right below an azimuth corresponding to the right eye, a sight hole is arranged at the left below an azimuth corresponding to the left eye, and the azimuth directions of the two sight holes are opposite in the work azimuth direction so as to promote the shadow to return to the azimuth of the word. The sighting target self-functionalized typoscope can be used for treating the eye diseases such as presbyopia, far sightedness, astigmatism, achromatopsia, cataract and the like, and the outer sight holes can also be used when people are in walking. The sighting target self-functionalized typoscope is different from the conversional patented article, can be used in front of the eyes, and can be used for changing the sight line direction to the direction opposite to the direction of the shadow in the word azimuth direction.

Based on an optic nerve formation mechanism that an organism simultaneously senses light and neurotransmitters, a photosynaptic neurotransmitter sensor is used for simultaneously sensing the light and the neurotransmitters, and a bionic visual perception research model regulated and controlled by the combined action of the light and the neurotransmitters is established. Neurotransmitter is used for regulating and controlling a photosynapse function to simulate the abnormal condition of optic nerve conduction, two abnormal conditions of amblyopia and color blindness in vision are simulated, and the individual visual difference of an organism is simulated. The light sensing condition of the photosynaptic neurotransmitter sensor is combined, the ability of capturing a moving light source and identifying an object contour in vision is simulated, and the bionic visual sensing function under the optic nerve abnormity and normal conditions is compared. According to the method, biochemical reaction and photoelectric stimulation are combined, and a more real bionic visual perception method is provided from the aspect of biological optic nerve conduction.
