Symptoms of cataract

The symptoms of presbyopia can be relieved in the early stage of cataract. Most of the elderly will have presbyopia symptoms. When they get older, the inflammatory cells will also age, leading to presbyopia. However, after suffering from cataract, presbyopia will be relieved due to the concave convex refractive change of lens in the early stage of cataract.

Secondly, the symptoms of monocular hyperopia or abnormal color vision will appear, that is, the patients will gradually appear the symptoms of single shadow or double shadow when the light irradiates the retina; In the early stage of the patient, the lens began to swell, and the epithelial cells increased, so that when the patient saw the light, he would overcome refraction, leading to color halo.

The early symptoms of cataract patients will appear blurred symptoms, that is to say, the vision of patients began to slowly blurred, sometimes blurred to see things, or patients in the sun to see light around the aperture, this is the first symptom of patients.
