Eyes take people to appreciate beautiful scenery and learn practical and interesting knowledge. Eyes also record the appearance of family and friends, but how much do you know about eyes?
1. About astigmatism
Astigmatism is a manifestation of abnormal refraction and a common eye disease. Basically, everyone has some astigmatism. Vision loss is closely related to the degree and type of astigmatism. People with mild astigmatism usually have normal vision, while those with moderate and high astigmatism have poor vision at both far and near. Simple astigmatism has a slight decrease in vision, while compound astigmatism and mixed astigmatism have a significant decrease in vision. If it is not corrected properly, amblyopia may occur.
Prevention and treatment measures
☞ Frequent eye massage is beneficial for preventing and controlling astigmatism, and it also helps with eye health, promotes blood circulation, and achieves the effect of protecting eyes and improving eye astigmatism.
☞ Pay attention to observation, find problems, and go to the optometry center for eye health examination in time. Establish an optometry file and check regularly. After finding that you have symptoms of astigmatism, you can choose to wear glasses for physical correction.
2. About playing with mobile phones after turning off the lights
In a dark environment, the pupils of the eyes will expand to adapt to the lack of light. In this way, when you use the mobile phone screen, your eyes will receive the light from the screen more concentratedly, increasing eye fatigue. And the mobile phone screen will release blue light. Long-term exposure to blue light will cause eye fatigue, dryness, decreased vision and other problems.
Prevention and treatment measures
☞It is recommended to turn on the lights when playing with mobile phones at night and avoid using electronic products in dark environments. When using a mobile phone, adjust the brightness to a comfortable brightness for the eyes to prevent eye fatigue
☞If it is only for viewing needs, you can choose projectors, TVs and other devices with larger screens and longer viewing distances, and retain some other light sources to relieve the visual pressure of the eyes.
About outdoor activities to prevent myopia
With the development of technology, children nowadays are basically exposed to electronic products, such as mobile phones, tablets, TVs, computers, etc. at an early age. Frequent use of electronic products is very unfriendly to the development of children’s vision and may cause myopia problems early. Children should be taken outdoors more often.
Under sufficient natural light and appropriate ultraviolet radiation outdoors, our pupils will become smaller, making the image clearer; at the same time, when we are outdoors, our eyes will switch between different objects of vision, making the eyeball’s adjustment function better.
Prevention and control measures
☞The core of outdoor sports is “outdoors”. It is appropriate to choose sports such as basketball, football, badminton, frisbee, running, etc., so that the eyes can switch between different objects of vision to exercise the ciliary muscles and promote blood circulation in the eyes.
☞Studies have found that the incidence of myopia will decrease significantly if 2 hours of outdoor activities are added every day.
About fitting reading glasses
Reading glasses also need to be tested at a professional optical store. Because the degree of the two eyes is different and the health conditions are different, the reading glasses bought casually on the roadside have the same degree of lenses for both eyes and a fixed pupil distance. After wearing for a long time, the eyes are prone to fatigue, and symptoms such as dizziness may occur, which is very harmful to the eyes.
Prevention and control measures
☞Go to a regular optometry center for optometry, and buy comfortable reading glasses according to the different degrees and different eye health conditions of both eyes.
