近视(nearsightedness)是一种视力障碍,通常意味着人们在观察远处的物体时会出现模糊不清的情况。这是因为眼睛的屈光度不正常,使得远处的物体在视网膜上的焦点不在正确的位置上。
近视的原因可能是眼睛过于长或者过于前凸,这会使得光线在进入眼睛之前就已经聚焦了。这种情况下,远处的物体就会看起来模糊不清。
近视也可能是由于眼睛过于强壮造成的。当眼睛的晶状体变得过于厚实时,远处的物体就会看起来模糊不清。
近视常常是遗传的,但也可能是由于长期使用近距离观看的行为造成的。例如,长期看电脑或者手机会导致眼睛的肌肉过度使用,从而造成近视。
英文例句:
Myopia, or nearsightedness, is a common vision problem that causes objects in the distance to appear blurry.
The cause of myopia is usually an abnormal curvature of the eye, which results in the focus of distant objects falling in front of the retina rather than directly on it.
Myopia can be caused by an eye that is too long or too protruding, causing light to be focused before it reaches the retina.
Myopia can also be caused by an overly thick crystalline lens, which causes distant objects to appear blurry.
