Levocyclophoria

Levocyclophoria is a medical term that describes a condition in which the eyeball deviates toward the left or right eye. This condition can be caused by various factors, such as injury, disease of the nervous system or eye muscles.

Levocyclophoria can lead to blurred vision, as well as problems in coordination of movements and orientation in space. It can also cause discomfort and pain in the eyes.

Treatment of levocyclophoria depends on the cause of its occurrence. If this is an injury, then surgery is necessary to restore the integrity of the eye and muscles. In case of nervous system disease, medications or physical therapy may be prescribed.

However, if levocyclophoria is caused by other reasons, then treatment may be more complex and lengthy. In any case, you must consult an ophthalmologist for diagnosis and appropriate treatment.



Levocyclophonia is a visual effect that can occur in a person actively looking at a mobile phone or computer screen. The article describes this phenomenon and its causes.

Left cyclophonia is characterized by the fact that the active part of human vision is fixed on the upper left quadrant of the screen of a mobile device, primarily on the Instagram window. Meanwhile, screen blinking, which gives the impression of continuous screen operation, causes visual focus to move smoothly from left to right along a vertical stalk emerging from the middle and far edges of the visible field. The phenomenon is a manifestation of “conical accommodative beam refraction” in the eye, i.e. conical focusing portion inside the eye. Thus, the visual beam, when looking at a window filled with a white pixel background, is refracted, bending slightly to the left, as if creating a conical focus aimed at the upper right corner of the screen. This phenomenon affects people who usually hold a mobile phone with their left hand. Also, the intensity of this effect will be stronger, the greater the visual adaptation of the eyes to the conditions of intense white light on the display. This phenomenon can be easily observed if you often look at your mobile phone or computer. If you turn off the screen and wait a few seconds, then turn the screen back on, the effect may disappear for a moment and reappear until your activity moves the active piece of visible background to the right side of the screen.
