Wuhan Medico Eye Hospital: What factors can lead to eye fatigue and dryness?

introduction

The eye is one of the most important sensory organs in the human body, but due to the change of modern lifestyle, more and more people will face the problem of eye fatigue and dryness. These problems may be caused by some habits and environmental factors in our daily life. This article will focus on Wuhan Medico Eye Hospital and discuss several main factors that lead to eye fatigue and dryness.

Screen usage time is too long

In modern society, many people stare at computers, mobile phones and TV screens for a long time. This has caused a huge burden on our eyes. First of all, the blue light of the screen will stimulate our eyes, resulting in eye fatigue and dryness. Secondly, long-term fixation makes the muscles of the eyeball tense and easy to cause fatigue. Finally, as we stare at the screen for a long time, we will unconsciously reduce the frequency of blinking, resulting in dry eyes.

Effect of blue light on eyes

LED backlight and OLED technology widely used in modern electronic equipment will emit a lot of blue light. These blue lights have high energy and can penetrate the cornea and lens of the eye and directly illuminate the retina. Prolonged exposure to blue light will lead to retinal cell death and pigment disorder, increasing the risk of myopia and other eye diseases. Therefore, reducing the use of electronic equipment for a long time and wearing blue light filter glasses are important measures to protect the eyes.

Decrease in blink frequency

Normally, people blink 15-20 times per minute, and staring at the screen for a long time will reduce the blink frequency. The function of blinking is to evenly smear tears on the surface of the eyeball to keep the eyes moist. If the eyes do not blink frequently, the tears will evaporate faster and the eyes will dry easily. Therefore, we should pay attention to regular rest and blink when using electronic equipment.

environmental factor

In addition to using electronic devices for a long time, the environment we are in will also have a certain impact on our eyes. Common indoor equipment such as air conditioning, heating, fans, etc. will cause poor indoor air circulation, resulting in dry air, which will make the eyes feel dry. In addition, outdoor sandstorms and air pollution can also irritate the eyes, causing eye discomfort and fatigue.

Indoor environmental factors

When working or living indoors, we often use air conditioning and heating to adjust the indoor temperature. However, the use of these devices will cause the humidity of the indoor air to drop, making the eyes easier to dry. In addition, staying in a closed indoor space for a long time will also cause the accumulation of harmful substances in the air and cause irritation to the eyes. Therefore, keeping good indoor ventilation and proper humidity is an important measure to protect eyes.

Outdoor environmental factors

Dust, particles, wind sand, etc. in the outdoor environment can also cause eye irritation. Prolonged exposure to these environments can cause dry and uncomfortable eyes. Measures such as wearing sunglasses, avoiding long-term exposure to irritating environment, and regularly washing eyes can alleviate eye discomfort.

summary

Eye fatigue and dryness are more and more common problems in modern life. Long time use of electronic equipment, exposure to dry indoor environment and exposure to environmental stimuli are the main factors leading to these problems. In order to protect our eyes, we should pay attention to controlling the use time of the screen, reducing the impact of blue light, maintaining an appropriate blink frequency, and paying attention to maintaining good indoor ventilation and appropriate humidity. In outdoor environment, avoid direct exposure to irritant environment, and use sunglasses reasonably. Through these measures, we can reduce the fatigue and dryness of eyes and protect the health of eyesight.
