Wearing presbyopes for a long period of time does not usually cause cataracts. Cataract is a visual disorder caused by abnormalities in the patient’s lens, the causes of which include aging, eye surgery, tumors, inflammation, physical damage, chemical damage, and medication. Wearing presbyopes for a long period of time can help patients alleviate the role of poor vision, and generally will not cause cataracts. Cataracts can cause patients to suffer from vision loss, blurred vision, double vision, color vision changes and other uncomfortable symptoms, and may cause blindness for those with more serious conditions. Therefore, when a patient is diagnosed with cataracts, he or she should be treated promptly. It is recommended that people with eye diseases or abnormalities undergo regular eye examinations and eat more vitamin-rich foods for the benefit of eye health.
