Early symptoms of cataract can be applied to pinoxin eye drops, glutathione eye drops and so on. 1. Pirenoxine eye drops: Pirenoxine can competitively hinder the binding of quinone compounds with lens water-soluble proteins due to its stronger affinity for these compounds than quinone compounds, thus preventing the denaturation of lens proteins. 2. Glutathione eye drops: Glutathione is an antioxidant that can help the body to remove oxygen free radicals and peroxides from the body, improve the function of the organism to fight against adverse environmental influences, and can prevent cataract progression. It is recommended that patients do not blindly use medication, if there is discomfort, timely medical treatment, standardized treatment under the guidance of a doctor.
