define myopia and hypermetropia, and how can it be corrected by drawing a diagram
Answers
Answer:
myopia is near slighted ness in which a person is able to see near objects clearly but not the distinct objects and hypermetropia is its opposite in which person is able to see far object clearly but not the near objects.
Answer:
Explanation:
Myopia is also known as near-sightedness or short-sightedness. Light rays do not focus on the surface of the retina but in front of it. This results in images being blurry when perceived. In such a case, distant images appear out of focus but objects nearby are seen clearly. This is why myopia is also called near or short-sightedness.
Farsightedness is also known as hyperopia. It is a refractive error in which distant objects are clearly seen, but close objects appear blurry. People experience farsightedness differently, and some people, more commonly when they are young, do not notice any problems with their vision. In addition, for people with significant farsightedness, vision can be blurry for objects at any distance, near or far.
Farsightedness and its Correction:
- Farsightedness or hyperopia is the inability of the eye to focus on nearby objects. The farsighted eye has no difficulty viewing distant objects. The lens can no longer presume the convex and curved shape lens that is needed to view the nearby objects. This vision problem can be corrected by using a converging lens.
- It will refract light before entering the eye and eventually decreases the distance of the image. By initializing the refraction process prior to light reaching the eye and the image of nearby objects is once again focused upon the retinal surface.
- Farsightedness is mostly seen among adults and occasionally in young people. If this vision problem happens among youth, the cause would rarely be related to the inability of the lens to assume a short focal length. The problem in this case is mostly related to an eyeball that is shortened.
- With the shortening of the eyeball, the retina lies closer than usual to the cornea and lens. This results in the formation of an image of nearby objects beyond the retina. To correct this problem, again the same converging lens is required for the adults.
