what is myopia and hetromyopia
Answers
Answer:
What is Myopia?
Myopia is the term used to define being shortsighted.
A myopic person has clear vision when looking at objects close to them, but distant objects will appear blurred. This is because light is focused in front of the retina and, being too far forward in the eye, things in the distance look blurred.
People typically become short-sighted as teenagers or in their twenties, with around three in 10 people in the UK being myopic.
What is 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.

myopia (short sightedness ) - can see near by objects clearly but cannot see distinct objects clearly
can be corrected using concave lens of appropriate power
hetromyopid (far sightedness ) - can see far objects clearly but cannot see near objects clearly

thank you .
