There are several clinical manifestations of refractive errors, such as myopia, hyperopia, or astigmatism, all of which fall under the category of refractive errors. The normal adult eye axis is approximately 24mm, and patients with refractive errors have eye axis measurements that are greater or less than this value, which prevents images from being clearly presented on the retina. In patients with myopia, images generally appear in front of the retina, while in patients with hyperopia, images typically appear behind the retina. Various types of refractive errors can be corrected by wearing glasses to improve vision, enabling patients to see clearly. Additionally, patients with myopia and astigmatism can also consider laser surgery treatment after reaching adulthood.
