近视以登高,远视以致远作文英文回答：
Myopia, also known as nearsightedness, is a common vision condition that makes it difficult to see objects that are far away. People with myopia can see objects clearly that are close to them, but objects that are farther away appear blurry. This condition is usually caused by the eyeball being too long or the cornea being too curved, which causes light rays to focus in front of the retina instead of on the retina. Myopia can be corrected with glasses, contact lenses, or refractive surgery.
Hyperopia, also known as farsightedness, is another common vision condition that makes it difficult to see objects that are close up. People with hyperopia can see objects clearly that are far away, but objects that are closer appear blurry. This condition is usually caused by the eyeball being too short or the cornea being too flat,
which causes light rays to focus behind the retina instead
of on the retina. Hyperopia can be corrected with glasses, contact lenses, or refractive surgery.
