What symptoms can cause eyestrain?

The eyes are actually a very fragile organ. If you use it to work for a long time, it will become tired and it will directly affect the health of the eyes. Eye fatigue can also lead to many uncomfortable symptoms, such as headaches, memory loss, tearing, photophobia, etc., so everyone should know how to protect their eyes and avoid overloading them.

Eye fatigue is mainly caused by the fact that when people concentrate on looking at the computer screen, they blink less often, resulting in a corresponding decrease in tear secretion. At the same time, the flashing screen strongly stimulates the eyes. In mild cases, patients may feel eye discomfort, pain in the eyeball or its surrounding area, soreness and swelling in the root of the nose or temple area, blurred vision, dry eyes, a feeling of pressure and burning, photophobia, double vision and tearing when using their eyes. In severe cases, there are obvious systemic symptoms such as eye pain, dizziness, nausea, vomiting, night sweats, pale complexion, slow heartbeat, tense neck muscles, shoulder pain, and may also have symptoms such as drowsiness, mental depression, insomnia and memory loss.

The harm caused by eye fatigue to people

1. Eye inflammation: Long-term suffering from dry eyes can lead to keratitis, scleritis, etc.

2. Decreased vision: For teenagers, their resistance is relatively low. They are more likely to suffer from eye fatigue if they face the computer for a long time, which can cause accommodation spasms and make it difficult to see far away, leading to true myopia.

3. Brain fatigue: Eye fatigue will directly lead to brain fatigue, and concentration and thinking ability will decrease, resulting in irritability and decreased efficiency.

4. Physical fatigue: Eye fatigue will lead to brain fatigue. Continuous brain fatigue will cause mental and psychological depression. Long-term accumulation will eventually lead to fatigue syndrome.

5. For teenagers, long-term close-up use of computers can cause accommodation spasms and make it difficult to see far away, which can lead to true myopia.

6. For people over 45 years old, the eyes' ability to adjust decreases, leading to presbyopia, close-up vision fatigue, and inability to use the eyes for a long time.
