How do normal vision of eye is affected by myopia and hypermetropia?
Answers
Answer:
When your eyeball is too long or the cornea -- the protective outer layer of your eye -- is too curved, the light that enters your eye won't focus correctly. Images focus in front of the retina, the light-sensitive part of your eye, instead of directly on the retina. This causes blurred vision.
Answer:
Nearsightedness (myopia) is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry. It occurs when the shape of your eye causes light rays to bend (refract) incorrectly, focusing images in front of your retina instead of on your retina.
Farsightedness (hyperopia)
With normal vision, an image is sharply focused onto the surface of the retina. In farsightedness (hyperopia), your cornea doesn't refract light properly, so the point of focus falls behind the retina. This makes close-up objects appear blurry.
