Myopia is a common ophthalmic disease, which refers to the focal point formed by parallel light passing through the refractive system of the eye in front of the retina, resulting in a scattered and blurry image on the retina. This refractive state is called myopia.
Myopia mainly refers to the inability of parallel light rays to form an image on the retina after refraction, resulting in blurred vision in front of the retina and affecting normal viewing. Myopia is clear, hyperopia is blurred, and the fundus or visible retina shows leopard like changes. Myopia is usually caused by long-term fatigue, genetics, and close range work. Long term overuse of the eyes can lead to a decrease in the elasticity of the crystalline lens, which is the main cause of myopia.
1、 Eye examination
Myopia needs to be diagnosed through visual acuity examination, corneal examination, examination of high myopia, and examination of other diseases. Treatment should pay attention to the following points:
1. Early detection and treatment to reduce further fatigue damage to the eyes caused by blurred vision
2. Actively treat diseases such as binocular vision abnormalities, decreased fusion function, and intermittent exotropia that can cause visual changes;
3. Develop personalized prevention and control measures based on the specific situation of the patient
2. Daily diet
1. Cassia seed
Cassia seed has a sweet and bitter taste, a cold nature, and is a good product for clearing the liver and improving vision.
2. Fish liver oil is beneficial for the eyes as it contains abundant vitamin A and vitamin D. Vitamin A is very helpful in maintaining normal visual function and immune system health. Lack of vitamin A can lead to dry eye syndrome, night blindness, and anemia.
3. Egg yolk: The vitamins contained in one egg are mostly concentrated in the yolk, such as vitamins A, D, E, etc. Egg whites mainly contain protein. Egg yolks can protect the eyes because they contain lutein and zeaxanthin, which can help filter harmful ultraviolet rays, delay eye aging, and prevent eye diseases such as macular degeneration and cataracts.
4. Corn, the biggest contribution of corn to the eyes, lies in its content of lutein and zeaxanthin, which have strong antioxidant effects and can clear harmful light entering the eye, protect the photosensitive area of the macular region, and prevent age-related macular degeneration and cataracts. Generally speaking, myopia is divided into congenital and acquired types, and acquired myopia is mainly caused by excessive eye use leading to excessive axial length. The main harm of myopia is that it makes it difficult to see distant objects clearly, especially the complications of high myopia, which will gradually increase. Conditions such as retinal detachment and macular hole can occur. The best prevention is to avoid excessive eye use, look less at mobile phones and computers, read and write for more than an hour, and try to look far away for a few minutes.
In short, for children and adolescents, it is best to go to the ophthalmology department of the hospital every six months for vision and optometry examinations. If myopia is found, it is necessary to go to the hospital for re examination every 3 to 6 months; Those with myopia of 100 degrees or above are required to wear glasses; Myopia below 100 degrees also requires glasses if there are obvious symptoms such as difficulty seeing far and squinting. Myopia is a concern for people nowadays. The causes of myopia include congenital and acquired factors. Congenital myopia refers to hereditary myopia, especially high myopia, which can be inherited, so it is important to pay attention to family history. For adolescent myopia, the most common issue is eye hygiene during their growth process. Nowadays, from kindergarten to primary and secondary schools, including preschool children, there is a growing emphasis on visual acuity testing. Because it has been found that the formation of myopia is actually related to long-term close range activities and prolonged staring at electronic screens. So from early childhood, it is important to pay attention to eye hygiene, strengthen outdoor exercise, and increase sunlight exposure. Now research shows that increasing sunlight and outdoor activities can reduce the occurrence of myopia.
