The dispersion of light in the eyes may be due to refractive error, lens clouding, vitreous clouding, corneal lesions, etc., which need to be treated with medication or surgery to address the cause of the problem. 1. Refractive error: After the external light passes through the refractive system of the eye, it can not accurately converge on the retina. When it converges in front of the retina, it is myopia; when it converges behind the retina, it is hyperopia; when it can not be converged into a point in the retina, it is astigmatism. It can be corrected by wearing corrective glasses, corneal refractive surgery, intraocular refractive surgery, scleral refractive surgery, and at the same time, pay attention to develop healthy eye habits. 2. Lens clouding: The lens is clouding because of aging, abnormal nutrition and metabolism, which leads to localized light propagation obstruction and makes the eyes see things with light dispersion. 3. Vitreous clouding: Inflammation, trauma and other factors lead to vitreous hemorrhage, vitreous clouding and light dispersion in the eyes. 4. Corneal lesions: corneal injury, keratitis and other lesions lead to corneal refractive abnormalities, so the eyes see things with light dispersion. The dispersion of light in the eyes may be related to a variety of factors, and you should consult a doctor for a clear diagnosis in a timely manner.
