The imaging principle of the human eye is similar to that of a camera, the image is inverted, and if the patient’s eye position is high, the image of the eye will be lower.
The optical principle of the human eye for small hole imaging, that is, the image of an object through the small hole (i.e., the pupil) presents an inverted solid image, the object image through the refractive system of the eye presents an inverted image in the fundus of the retina.
The same object is imaged in the macula of the fundus of the eye in the normal eye position. When there is a high or low eye position, the object is imaged above the macula of the eye in the high eye position.
When the right eye position is high, the inverted image of the retina of the right eye is higher than that of the left eye, but when the two objects are transmitted to the brain through the optic nerve, and the principle of inversion will reverse the two inverted objects to a positive image when the object image is transmitted to the brain, so that the object of the high eye position will be in a lower position.
It is recommended that patients with abnormal vision should seek medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
