Answer:
Myopia
Myopia is the term for nearsightedness. Myopia results when parallel light is focused in front of the retina. Only objects closer to the eye have a clear vision and can be properly focused on the retina. This defect is most usually linked with an elongated eyeball.
Hypermetropia
Hypermetropia due to a short eyeball, causes parallel light to be focused behind the retina. This happens if the cornea does not refract the light enough. People suffering from hyperopia have blurred vision of near objects and a clear vision of farther objects.
