Sighting target self-functionalized typoscope without limits on size and azimuths of sighting target for treating low-vision oculopathy

Abstract

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.

Description

field of invention [0001] The invention relates to a vision aid for various low-vision eye diseases (presbyopia, myopia, hyperopia, astigmatism, color blindness, and cataract) based on self-efficacy. Background technique [0002] Existing low-vision eye disease vision aids can only treat a kind of eye disease, and some of them are different from the principles of the present invention. Contents of the invention [0003] Technical method: make medical and disease visual mark on the lower left of the position opposite to the left eye center on the existing eye protection sheet, but it is empty but not see-through. Low vision eye disease can see words with shadow. For example: Myopia is 10 meters to 300 meters away from the wall. The word 0 on the wall seems to be not far from the wall. The shadow of the word is shown on the wall. Reason: When reading a book, the direction of the line of sight of the two eyes is too oblique to the eye plane, and they look at the same direct...
