The essential difference between amblyopia and myopia Amblyopia is mostly seen in preschool, and the traditional definition of amblyopia in China is a person with corrected visual acuity below 0.9 without obvious organic pathology. However, the latest diagnostic criteria for amblyopia in children are: below 0.5 for children under 3 years old, below 0.6 for 4-5 years old, below 0.7 for 6-7 years old, and below 0.8 for 8 years old. amblyopia cannot be restored to normal vision even with glasses. Myopia is a condition in which the eye cannot see distant objects but sees near objects clearly. With refractive rest, distant objects do not converge on the retina and form a focal point in front of the retina, resulting in visual distortion and blurring of distant objects. Amblyopia and myopia are different Amblyopia is an eye disease that seriously endangers the development of visual function in young children. The greatest danger of amblyopia is that the child not only has low vision in both eyes or one eye, but also does not have perfect binocular vision and does not have fine stereoscopic vision, i.e. both eyes cannot be used at the same time, or both eyes do not cooperate, which is medically known as stereo blindness. Stereopsis is the inability to see the distance and height of objects and to judge one’s position in space, which affects future career choices and a lifetime of destiny. Myopia is not only a loss of vision, but also a loss of the ability to attend a school or pursue a career that is desirable because the vision does not meet the requirements. However, myopia is not accompanied by other visual impairments and vision can be corrected. The best treatment for amblyopia is before the age of 7. After the age of 12, the effect of treatment is greatly reduced, and after the age of 18, there is almost no possibility of treatment. Amblyopia is treated clinically mainly with masking therapy and amblyopia training, which is a long-term process. However, missing this treatment time will be a lifelong regret.
