Will people definitely get cataracts when they get older?

As time goes by, our bodies go through many changes, some of which are part of the natural aging process. Among the many age-related health problems, cataracts are a common and serious blinding eye disease that affects vision. They account for a large proportion of blindness in patients aged 45 to 60 years old, [3] and have a great impact on patients' normal life and work. So, will people definitely get cataracts when they get old?

The relationship between age and cataracts

The occurrence of cataracts is closely related to age. As we age, the metabolism of the lens slows down, abnormal protein aggregation increases, and the risk of cataracts increases. Although the rate of progression of cataracts varies from person to person, almost everyone will encounter this problem at some age.

Why aging causes cataracts

The main components of the lens are water and protein. These proteins may become abnormal as we age and begin to aggregate or deposit, causing the lens to become cloudy. This process is like the gradual graying of hair, which is a natural aging process. [1]

Does everyone get cataracts?

Although age is one of the main risk factors for cataracts, not every elderly person will develop cataracts. Some people may delay the onset of cataracts or even never develop them. Some people may have a higher risk of developing cataracts due to genetics, lifestyle or other health factors. Given the growing elderly population, the number of cataract patients worldwide is also increasing. [2]

How to prevent and detect cataracts early【3】

Regular check-ups: Regular eye exams can help detect cataracts early and allow for prompt treatment.

Protect your eyes: Avoid prolonged exposure to UV rays and wear UV-blocking glasses.

Eat a healthy diet: Get enough vitamins and antioxidants, such as vitamins C and E, and lutein.

Control chronic conditions: Diabetes and other chronic conditions may accelerate the development of cataracts, so controlling these conditions is essential for eye health.

Cataracts are indeed closely related to age, and through a healthy lifestyle and regular eye examinations, we can reduce the risk of the disease and take appropriate preventive measures or undergo timely surgical treatment.
