My friend said there was no light in my eyes. What should I do?

The causes of dull eyes are normal phenomena, poor mental state, visual fatigue, decreased vision and so on.

1. Normal phenomenon, the patient has swollen eye bubbles, and half of the eyeball is covered by the upper eyelid, thus giving people a feeling of dull eyes.

2. Poor mental state, long-term staying up late leads to serious lack of sleep, which may have an impact on mental state and lead to the lack of eyes.

3. Visual fatigue, long-term use of electronic products, eye blood circulation disorders, so that the eyelids are slack and weak, which leads to the lack of eyes.

4. Poor eyesight, due to myopia, hyperopia or astigmatism, habitual squinting in order to see things more clearly, resulting in eyes without god.

In the case of dull eyes, it is recommended to seek medical advice as soon as possible.
