How to prevent high myopia? Teenagers need to increase outdoor activities

Abstract: not necessarily. There are two kinds of Shadows: fixed shadows and floating shadows. If there is a fixed shadow in front of you, it indicates retinopathy, such as retinal hemorrhage, retinal hole and retinal detachment. If treatment is delayed, it is easy to cause blindness.

high myopia eyes appear dark shadow will cause blindness?

and

eyes with myopia degree of more than 600 degrees are high myopia. Almost all high myopia eyes have eye axis growth and significant thinning of sclera at the posterior pole of the eye. With the growth of time, the retina and choroid will shrink and become thinner and thinner.

people with high myopia are more likely to have dark shadows, but will they be blind if they have dark shadows? Not necessarily. There are two kinds of Shadows: fixed shadows and floating shadows. If there is a fixed shadow in front of you, it indicates retinopathy, such as retinal hemorrhage, retinal hole and retinal detachment. If treatment is delayed, it is easy to cause blindness. Therefore, when there is a fixed shadow, you need to see a doctor in time to avoid visual damage. Most people with high myopia will have the second kind of shadow, floating shadow, which flutters gently in front of their eyes like mosquitoes and hair. When their eyes look at the white background, the shadow flutters especially obviously. Floating shadow is mainly vitreous opacity, which does not affect vision. Generally, there is no need to be particularly nervous. You can have an eye examination once a year or half a year. Pay attention not to take part in strenuous sports in life, such as roller coaster, bungee jumping, etc. If retinal hemorrhage occurs and red light and flash appear when looking at things, you need to see a doctor in time. How can

and

prevent and treat high myopia?

teenagers increase outdoor activities

high myopia can be prevented and treated early. There are obvious differences in the prevention and treatment methods between teenagers and adults:

for teenagers, there are two main prevention and treatment methods:

1 Increasing outdoor activity time

and

myopia are the results of genetic and environmental factors. The research by Professor He Mingguang of Ophthalmological Center of Zhongshan University showed that “for 6 year olds, 40 minutes of outdoor activity time per day can reduce the incidence rate of myopia in 3 years.” So we should let children have more outdoor activities;

2. Wearing OK glasses

before the age of 18, teenagers’ vision is unstable and easy to grow. Although wearing OK glasses can not completely cure myopia, it can significantly delay the progress of myopia. The number of teenagers wearing frame glasses increased by 68 degrees a year, and the number of teenagers wearing OK glasses increased by 16 degrees a year.

for adults, we should pay attention to two aspects in the prevention and treatment of myopia:

1. Don’t be overtired.

people with myopia should pay attention not to be overtired in their daily work and life to avoid deepening myopia and forming high myopia. They should pay attention to eye hygiene, use their eyes for about 40 minutes, and let their eyes rest for about 10 minutes, Look into the distance; At the same time, avoid playing football, basketball, diving and other dramatic sports to prevent retinal detachment;

2. Correct myopia in time

adults should correct high myopia in time, The main correction methods include: wearing corneal contact lenses (contact lenses), wearing frame glasses, surgery (femtosecond laser, anterior chamber human lens, posterior sclera reinforcement surgery, etc.) “when correcting high myopia, wearing corneal contact lenses has a better effect, because the higher the degree of eyes, the thicker the lens of frame glasses, and the things seen by thick lenses will shrink.”
