1.	What are the differense between myopia and hetromyopia
Answer» MYOPIAMyopia is a condition in which the people cannot see objects which are beyond the ‘far point’. Far Point is the point of maximum distance at which the eye lens can form an image on the retina. Myopia is also called as’Near- Sightedness’, in which person cannot see the far objects clearly but can see the near objects clearly. The Myopia can be corrected using Double-Concave lens.EXAMPLE: A student who is unable to see the letters on the classroom board is suffering with Myopia.HYPERMETROPIAHypermetropia is a condition in which the people cannot see objects placed between the ‘Near point’ and the point of least distance of distinct vision. ‘Near Point’ is the point of minimum distance at which the eye forms clear image on retina. Hypermetropia is also called as ‘Far-Sightedness’ because the individual cannot be able to see the near objects clearly, but can see the far objects clearly. The Hypermetropia is corrected using the Double- Convex lens MYOPIA 1. It is short-sightedness. 2. It is caused by elogation of eye ball or by excessive curvature of the eye. HYPERMETROPIA1. It is far-soghtness.2. It is caused by shortning of eye ball or by focal length of the eye len is too long.
