The causes of eyeball protrusion in myopic patients are mainly the deformation of the skin of the inner corner of the eye due to the compression by the nosepiece of eyeglasses, and the lengthening of the eye axis. If myopic patients wear frames for a long time and the weight of the frames is too big, the nosepiece will press the skin of the inner corner of the eye, resulting in localized skin depression, and thus the eyeball will be relatively protruding from the appearance. Myopia patients usually accompanied by the lengthening of the eye axis, generally myopia every 300 degrees of growth, the length of the eye axis will increase by 1 millimeter, that is, the diameter of the eyeball will be expanded by 1 millimeter, resulting in the eyeball becomes larger, will inevitably cause the eyeball protrudes, the higher the myopia, the more pronounced the protruding eyeballs. If myopic patients have protruding eyeballs, they should go to the ophthalmology department of the hospital in time, and be diagnosed by the doctor through detailed examination to confirm the specific cause, and then they can take targeted treatment to eliminate the symptoms.
