Myopia is a kind of ametropia. When the eyes are relaxed, parallel light enters the eyes and focuses in front of the retina, resulting in the inability to form a clear image on the retina, which is called myopia. At this time, checking the optometry will prompt the degree of myopia. For example, it is usually called myopia 50 degrees and recorded as "-0.50D".
When the eyes relax, the parallel light from the outside enters the eyes, and its focus just falls on the retina, forming a clear image, which is called face up; If the focus cannot fall on the retina, it is called ametropia.
Myopia is a controllable and correctable disease, which generally does not affect normal life and work. "Wearing glasses will aggravate myopia" is a misunderstanding, so don't have too much psychological burden. After teenagers find myopia, parents should treat it scientifically, avoid transmitting anxiety to their children, nip in the bud and treat it scientifically after it happens.
