Generally, myopia is the result of an increase in the length of the eyeball, which changes from a circular shape to an elliptical shape. When looking at a distant scene, the crystal cannot change shape by adaptation, so that the image cannot be projected on the retina correctly. Especially children's crystallines are still in the developmental stage, which are more prone to shape changes due to overuse of the eye. From the foregoing, it is clear that how to restrict the object to be seen from being too close to the eye is an important issue for modern people.
