Question

what do you mean by short sightedness or long hypermetropia
​

Answer 1

Answer:

The most common vision problem where the closer objects are easy to see, while further objects are blurry, this is known as short- sightedness. The problem when the distant objects are clearly visible than the nearby objects is known as long-sightedness, far-sightedness or hyperopia.

Answer 2

short sightedness:

Short-sightedness, or myopia, is a very common eye condition that causes distant objects to appear blurred, while close objects can be seen clearly.

long hypermetropia:

Hypermetropia, sometimes called hyperopia, is the term used to define being longsighted. If you are hypermetropic, the image of a nearby object is formed behind the retina. This means that light is focused too far back in the eye, causing things which are close up to appear blurred.
