Which of the following defects of vision is as a result of the eye ball being too long?
Answer Details
The defect of vision that is a result of the eye ball being too long is short sight. Short sight, also known as myopia, is a condition where distant objects appear blurred while near objects are seen clearly. In short-sightedness, the light entering the eye is focused in front of the retina instead of on it, due to the elongated shape of the eyeball. This makes it difficult for the eye to see distant objects clearly. To correct this defect, concave lenses are used to diverge the incoming light rays and bring them to focus on the retina.
