children at home are myopic and anxious parents. “What is myopia, why is myopia, why does the degree of myopia deepen, and how to treat myopia…” a series of questions have become the most frequently asked questions by parents in the optometry clinic. In order to let parents fully understand these questions, today we invite ophthalmologists to answer them one by one.

what is myopia

the human eye is like a camera. Myopia is that when the eye looks far, the image falls in front of the “film”, the feeling is blurred, and becomes clear when it gets close.

the following symptoms need to be vigilant against myopia.

like to watch TV

can’t see the blackboard clearly, or always copy the wrong blackboard

when reading and writing, they are very close to the book

like to squint when looking away, or hold the bridge of the nose with their hands.

eyes are easy to get tired, Often rub the eyes

why myopia

at present, there is no definite conclusion about the causes of myopia, which can be roughly summarized into the following three aspects:

1 genetic factors

myopia can be inherited. Children with both parents’ myopia and children with one parent’s myopia have a much higher risk of myopia than ordinary children.

2 environmental factors

reading and playing with mobile phones for a long time, the light is too dark or too bright, reading in a bumpy environment, incorrect writing posture and other nonstandard close eye use are all important reasons for myopia.

3 physical factors

malnutrition, too little outdoor exercise and some diseases can also cause myopia.

what are the common myopia

1? The eye axis of axial myopia

is the length of the camera from the lens (cornea) to the film (retina). Generally, the normal value of ocular axis after 7 years old is 23.5 ~ 24mm. For every 1mm increase of ocular axis, myopia increases by 300 degrees. Axial myopia accounts for 90% of myopia.

and

2 excessive corneal curvature – curvature myopia

and

normal corneal curvature radius is 7.8mm and the shape is close to the spherical surface. If the cornea is excessively curved, the curvature radius will become smaller and the corneal shape will be convex, which is manifested as myopia.

pseudomyopia

when the lens adjustment cannot be relaxed, it will show the same symptoms as myopia – blurred vision, clear vision near, and the result of direct optometry will be higher than the actual power. After the examination of the ciliary paralysis (mydriasis), the regulation effect was relieved, and the high myopia degree disappeared. This part of myopia is called pseudomyopia.
