Causes of occurrence and development of myopia
Myopia, or myopia, is an ocular disease with ametropia. The occurrence and development of myopia are affected by many factors, including genetic factors, environmental factors, lifestyle and eye habits. Understanding these factors plays an important role in the occurrence and development of myopia.
Genetic factor
Genetic factors are one of the main reasons for the occurrence and development of myopia. The study found that myopia often has family aggregation. If a family member has myopia, other members are more likely to develop myopia. Genetic factors lead to differences in eye morphology and visual system development, thus increasing the risk of myopia.
In addition, the heredity of myopia is also related to the degree of myopia of parents. If both parents have myopia, the probability of children suffering from myopia is higher. Therefore, children with a family history of myopia in their families need to strengthen the awareness of protection of vision health and carry out eye examinations regularly.
However, even if there is no family history of myopia, the occurrence and development of myopia cannot be ruled out. Environmental factors play an important role in the occurrence of myopia.
environmental factor
In modern society, it has become a common phenomenon to use eyes for a long time and close distance. Long time staring at computers, mobile phones and other close objects will lead to over adjustment of the eye and increase the risk of myopia. In addition, the number of blinks will be reduced when using electronic equipment, which will lead to the rapid evaporation of tears on the eye surface, resulting in eye fatigue.
In addition, the bad factors of ambient light will also have a negative impact on vision. Long term exposure to dark light will increase the incidence of myopia, because the eyeball needs to work harder to see objects clearly. Inadequate outdoor activities will also weaken the eye protection ability, further exacerbating the occurrence of myopia.
In order to prevent the occurrence of myopia, it is critical to reduce the time of using eyes in close distance as far as possible, maintain a good posture of using eyes, and properly adjust the ambient brightness.
life style
The occurrence and development of myopia is also closely related to personal lifestyle and eye habits. Maintaining the same posture for a long time, such as looking down at the mobile phone, sticking to a posture while reading, will increase the burden of eye adjustment. In addition, lack of outdoor activities and sports will also increase the risk of myopia.
Regular lifestyle and healthy living habits are essential to prevent myopia. For example, regular outdoor activities, avoiding excessive fatigue and eye use, and adjusting the sitting posture and reading distance will help reduce the occurrence and development of myopia.
Habit of using eyes
Good eye habits are very important for good eyesight. Long term eye use requires proper rest time, and visual relaxation exercises should be carried out at regular intervals. In addition, the reasonable arrangement of eye use time and the alternation of close eye use and remote eye use can reduce the risk of eye fatigue and myopia.
The sitting posture, eye position and distance also need attention. Sitting too close, reading too close, and using eyes in close proximity when lowering the head will increase the burden of eye adjustment, and thus increase the risk of myopia.
summary
The occurrence and development of myopia can be caused by genetic factors, environmental factors, lifestyle and eye habits. Understanding these factors and taking corresponding preventive measures, such as living regularly, using eyes properly and maintaining good eye habits, will help reduce the risk of myopia. Therefore, it is suggested that everyone should pay close attention to the health of eyesight and carry out eye examinations regularly to prevent the occurrence and development of myopia.
