Nearsightedness and Farsightedness Nearsighted people experience blurred vision while looking at distant objects, such as street signs viewed from inside a car. Conversely, farsighted people experience blurred vision while looking at nearby objects, such as words on a page. The causes of these two conditions differ as well. Nearsightedness, or myopia, occurs either when a person's eye is too long from back to front or when thể cornea (the clear layer at the front of the eye) is too curved. On the other hand, farsightedness, or hyperopia, results when the eye is too short or when the cornea is not curved enough. Fortunately, corrective lenses can restore normal vision in both cases. As you might expect, these lenses are of opposing types:…
