The last reason is rare, but it does exist in reality. It's called standing behind the ball. Generally speaking, there are tumors behind the eyes. As the tumor gets bigger and bigger, the eyeball is pushed forward. When treating, we need to know whether the tumor is benign or malignant. If it is benign, surgical resection can be selected according to the size of the tumor, and the malignant tumor needs further radiotherapy or chemotherapy.
Many parents think that wearing glasses will make their children's academic qualifications higher and higher, so they will not let their children wear glasses all the time, only when they are studying. However, this method of using eyes is unscientific. The doctor said that taking off glasses frequently will lead to higher and higher myopia, and high myopia will make eyeballs pop out.
In addition, there is an interesting knowledge about cold eyes. One of the reasons why each of us has a vague childhood memory is that the axis of the baby at birth is only a dozen millimeters, and the scenes we see are all displayed by hyperopia. In other words, the image formed in childhood is very vague, and the memory ability of infants is not perfect. With the growth of age, these memories will gradually become reflections.
In any case, we should develop the habit of caring for our eyes from an early age, and don't let our children touch electronic products too early. There are genetic signs of high myopia. If you don't want your next generation to wear glasses, please ask adults who have never seen bad eyes to protect your eyes. No matter how good glasses are, they are not as convenient as the original ecological eyes.
