How to protect eyesight?
It is very important for everyone to protect their eyesight. Professor Qiu Xuan of Sun Yat sen Eye University is a well-known ophthalmologist in China. He shared some simple and effective methods to protect our eyesight.
Maintain correct eye position
Staring at the computer screen, mobile phone or other close eyes for a long time is a common eye posture for modern people. However, the wrong eye position will have a negative impact on vision. Professor Qiu Xuan suggested that we take the following measures to maintain correct eye posture:
First, keep the correct eye distance. For mobile phones and computer screens, we should keep a distance of 30-50 cm from the screen to reduce eye fatigue. Secondly, pay attention to eye rest. An eye rest of 5-10 minutes should be taken every hour to avoid prolonged continuous eye use. Finally, correct sitting posture is also important. We should keep an upright sitting posture, and keep perpendicular to the screen to avoid excessive head tilt.
Correct eye posture is the basis for protecting vision health.
Scientific diet
Diet has an important impact on vision health. Professor Qiu Xuan suggests that we take the following foods that are good for eye health:
First, take more food rich in vitamin C. Vitamin C is an important nutritional component of eye tissue, which can effectively resist the oxidation of eye cells. For example, citrus fruits, strawberries and tomatoes are all rich in vitamin C.
Secondly, increase the intake of foods rich in vitamin A. Vitamin A is an important nutrient required by retinal cells and helps maintain normal vision. Carrots, spinach and carrots are all foods rich in vitamin A.
In addition, eating foods rich in omega-3 fatty acids is also good for eye health. Omega-3 fatty acids play an important role in reducing intraocular pressure and preventing dry eye. Fish, flaxseed and nuts are all foods rich in omega-3 fatty acids.
Through scientific diet, we can provide enough nutrients to the eyes to protect vision health.
Moderate eye exercises
Eye exercises are a simple and effective way to exercise eye muscles. Professor Qiu Xuan recommends the following common eye exercises:
First, close your eyes and do eye movements. After closing your eyes, slowly rotate your eyes 10 times clockwise and 10 times counterclockwise. This exercise helps relax the eye muscles.
Secondly, adjust the distance. Put your index finger in front of you, look at it, and then slowly move it forward until you can't see it clearly. Then slowly pull the index finger away until you can see it clearly. This kind of exercise is helpful to the adjustment of the hyperopia and myopia of the eyes.
In addition, you can also exercise the eye muscles by closing your eyes and gently pressing your eyes, blinking and eye movement.
Appropriate eye exercises can improve the blood circulation of the eyes, reduce eye fatigue, and improve eyesight.
Regular eye examination
Regular eye examination is an important step to protect vision health. Professor Qiu Xuan stressed that everyone should regularly (at least once a year) go to an eye hospital for eye examination, so as to find and treat eye diseases in a timely manner.
Eye examination can help us detect data such as diopter, intraocular pressure, corneal curvature, and find clues of early ophthalmic diseases. Through timely detection and treatment, we can protect our vision and prevent vision loss and other eye diseases.
To protect eyesight health, we need to consider and act from many aspects, from correct eye posture to scientific diet, to moderate eye exercises and regular eye examinations. Only by comprehensively taking these measures can we guarantee our eyesight health.
summary
Protecting eyesight health is a problem that everyone should pay attention to. By maintaining correct eye posture, scientific diet, moderate eye exercises and regular eye examinations, we can effectively protect our eyesight. Professor Qiu Xuan has provided us with some simple and practical methods to better protect our eyes and prevent eye diseases.
