People suffering from cataract often block the light because of the turbid lens, so that the light can not be projected onto the retina well, which leads to blurred vision. This situation is very common in people after 40 years old, and the incidence will increase with age.
There are many reasons for cataract, such as aging, local nutritional disorders, genetic, immune and metabolic abnormalities, trauma and so on. Among them, we will find that nutrition is also a factor affecting the incidence of cataract.

1, to avoid excessive eye use.
Nowadays, many people use their eyes unsanitary and overuse them. If you are old, it will not only aggravate myopia, but also make your eyes too tired, which is not conducive to eye health over time.
Therefore, in order to protect eye health and reduce the occurrence of cataracts, we should pay attention to protecting our eyes, let them relax after using for one hour, and then avoid reading in the dark for a long time.
2. Avoid looking at the sun.
Studies have shown that exposure to sunlight every day 1 hour increases the risk of cataract 10%, and the probability of outdoor workers suffering from cataract is three times that of the former.
This is because long-term exposure to the sun, the ultraviolet rays contained in the sun will lead to chronic cumulative lens damage, thus inducing or accelerating the formation of cataracts.
In order to avoid this situation, we should watch less sun and then wear sunglasses, especially in summer, to prevent eye injuries.
3, eye massage
Massage on the eyes is a good way to protect the health of the eyes, which can accelerate the blood flow and circulation of the eyes, thus improving the immunity of the eyes, thus helping to delay the development of lens opacity and prevent the occurrence of cataracts to some extent.
Step 4 drink plenty of water
Drinking water is very important to our health. Drinking water at ordinary times can keep our bodies in good condition. However, if the body is lacking, the normal metabolism in the body will be disrupted, resulting in some metabolic wastes not being excreted well, thus affecting the lens and possibly inducing cataracts.
Studies have found that excessive salt intake is also related to the occurrence of cataracts. Drinking more water helps to excrete excess salt in the body, which shows that drinking water regularly is indispensable to health.
