Ques:Answer the following question given this paragraph: In myopia, the eye is too long. Below, you can see how images are focused on the retina of someone with myopia ( Figure below ). Myopia is corrected with a concave lens, which curves inward like the inside of a bowl. The lens changes the focus, so images fall on the retina as they should. Q: What vision defect occurs because the eye is too long? Choices: - hyperopia - blindness - astigmatism - myopia A:

Ans:myopia
