Myopic glasses see how near blurred is to return a responsibility

Myopic glasses to see near blurred reasons are mainly related to the refractive state of myopia. The following is a detailed analysis: 1. refractive error Myopic eye is characterized by long axis of the eye or the refractive system of the eye is too strong, resulting in light convergence in front of the retina, forming a blurred hyperopic image. When a nearsighted person wears glasses of appropriate power, he or she should theoretically be able to see distant objects clearly. 2. Accommodation and Aging With age, the accommodation of the eyes gradually weakens, which is called presbyopia. Presbyopia mainly affects middle-aged and elderly people. When they look at nearby objects, the lens of the eye does not adjust its shape sufficiently, causing the light to not focus accurately on the retina, resulting in blurred vision. But this is not a problem caused by nearsightedness. 3. The power of glasses is not correct. If the power of nearsightedness glasses is not accurate, it may cause blurred vision near or far. For example, if the power is too high, the light will converge too much in front of the retina, resulting in blurred vision; if the power is too low, the light will not converge enough behind the retina, resulting in blurred vision.
