How to prevent near red light injury in the ophthalmology department of Zhongshan Hospital, Guangzhou
More and more studies show that using electronic equipment at close distance for a long time and exposing to a lot of light will cause damage to our eyes, including near red light damage. Near red light is light with a wavelength between 700 nm and 1000 nm, which can easily penetrate eye tissues and cause damage to retina and lens. Here, we will introduce some measures taken in the ophthalmology department of Zhongshan Hospital in Guangzhou to prevent near red light injuries.
1. Tips for using video display
In recent years, people have been using electronic devices for a longer time, including computers, mobile phones, tablets and other devices. However, staring at the screen for a long time is easy to cause eye fatigue and near red light damage. In order to reduce this injury, the ophthalmology department of Guangzhou Zhongshan Hospital suggests the following techniques:
First, keep a certain eye distance. Adjust the screen to a position about 30-40 cm away from the eyes to reduce the direct exposure of near red light to the eyes.
Next, adjust the brightness and contrast. Adjust the brightness of the screen to the extent appropriate to the surrounding environment to avoid eye injury due to the too bright or too dark screen.
In addition, take regular rest. Every once in a while, you should let your eyes rest and look at the distant scenery to relax them.
2. Eye protection during outdoor activities
During outdoor activities, the eyes are often exposed to sunlight, and the harm of near red light is relatively increased. The following are some preventive measures recommended by the ophthalmology department of Guangzhou Zhongshan Hospital:
First, wear sunglasses. Choose sunglasses that can effectively block the near red light, especially those with UV 400 protection.
Next, put on your hat. The hat can provide additional light blocking for the eyes and reduce the chance of the eyes being exposed to direct sunlight.
In addition, avoid exposure to strong light, and try to choose a sheltered place to avoid direct exposure to near red light.
3. Diet and eye health
Diet is also closely related to eye health. The following are some nutritional suggestions recommended by the ophthalmology department of Zhongshan Hospital in Guangzhou for combating near red light injury:
First, increase vitamin intake. Foods rich in vitamin A, C and E, such as carrots, oranges and nuts, can help the eye tissues fight against the damage of near red light.
Secondly, take folic acid and lutein. These nutrients can protect the retina and lens from near red light, and can be found in green leafy vegetables, egg yolks and citrus fruits.
In addition, keep a balanced diet. Take more food rich in protein, minerals and other vitamins to promote eye health.
4. Regular eye examination
Regular eye examination is an important part of preventing near red light injury. In the ophthalmology department of Zhongshan Hospital in Guangzhou, professional ophthalmologists will conduct a comprehensive eye examination to ensure eye health, and timely find and deal with any eye problems. Through regular inspection, we can have a clearer understanding of eye health and prevent potential near red light injuries.
To sum up, in the ophthalmology department of Guangzhou Zhongshan Hospital, the measures to prevent near red light injuries mainly include the use of video monitors, eye protection during outdoor activities, diet and eye health, and regular eye examinations. Following these suggestions can minimize the damage of near red light to eyes and protect eye health.
