What is the reason for blurred vision?

Patients must know that if their vision slowly declines and there is no pain, they should be careful whether they have cataract. Senile cataract is one of the most common types of cataract in clinic. It is a degenerative change in the process of lens aging, especially in the middle-aged and elderly people over 50 years old. Many patients have told me that they hope to take medicine for treatment, which is a misunderstanding.

They should go to ophthalmology department for professional examination at least once a year.

This is an aging change of retinal cells in macular area, which is one of the main causes of blindness in people over 60 years old. Age is the main pathogenic factor, in addition to hypertension or cardiovascular disease, family history, long-term exposure to blue light and sunlight, and low nutritional level.
