Factors causing eye fatigue and dryness

In modern society, people are prone to eyestrain and dryness when they face electronic screens for a long time, especially office workers. The factors that may lead to these problems will be discussed from four aspects below.

Watching electronic screen closely for a long time

Whether we use computers, flat screen TVs and mobile phones at home or computers in the office, we focus on the electronic screen in close proximity for a long time. This makes our eyes need to adapt to close vision all the time. Long time use will lead to eye muscle fatigue, which will lead to the problem of dry eyes. In addition, the radiation from the electronic screen will also affect the health of the eyes. Therefore, we need to take appropriate measures to reduce eye fatigue and dryness.

First of all, we should take regular breaks, stay away from the screen every 30 minutes, and close our eyes for a rest of 5 to 10 minutes. In addition, adjust the screen brightness and contrast to ensure proper ambient light.

Poor use of glasses or contact lenses

Wearing unsuitable glasses or using contact lenses for a long time are also important reasons for eye fatigue and dryness. Inaccurate glasses or contact lenses are not suitable for individual conditions, which may cause the eyes to make excessive efforts to adapt to lenses or contact lenses. This will make your eyes tired and dry.

In order to avoid this problem, we should regularly check and update the degree of glasses, choose contact lenses suitable for our own eyes, do not wear contact lenses for a long time, and follow the correct use and care methods of contact lenses.

environmental factor

The dry environment is another important factor that causes eye fatigue and dryness. Dry indoor environment, such as office air conditioning, air pollution, smoking and other factors, will increase the rate of water evaporation in the eyes, resulting in dry eyes.

In order to improve this situation, we can increase the indoor air humidity, use humidifiers to maintain appropriate humidity, and try to avoid smoking and air pollution.

Lack of eye care

Finally, the lack of eye care is also one of the reasons for eye fatigue and dryness. Unreasonable living habits, such as staying up late, not paying attention to diet, lack of eye exercises, etc., will cause damage to eyesight.

In order to protect the health of our eyes, we should develop good living habits. Get enough sleep, eat a balanced diet, and eat more vitamins A, C, E and ω- 3 Fatty acid food. Carry out eye exercises, such as often looking at distant scenery, and then blink several times, while avoiding exposure to ultraviolet radiation in the open for a long time.

In a word, the main factors that cause eye fatigue and dryness are long time watching electronic screen closely, wearing bad glasses or contact lenses, dry environment and lack of eye care. In order to protect the health of our eyes, we should take appropriate measures and form good living habits.
