Long Sightedness and Short Sightedness

Introduction:

Taking care of our eyes are very important. The gift of vision should be appreciated and taken good care. We must never take for granted the beauty of the sight. The human eyes are brilliantly designed in such a way to perceive light and capture an image. The principle of a camera is developed by how a human eye works. We always feel if only our capture with our cameras that our eyes could see.

Our body works on the principle where if we eat healthily our body also stays healthy and functions properly. Just like the automobiles need fuel to operate, the organs in our body needs certain nutrients to get running and function properly. If you don’t provide enough fuel to your organs, then they will stop working. The Eye is the organ of vision, and we need to eat the important nutrition our eyes need to make it function properly.

Before discussing long sightedness and short sightedness let us understand some basic terms used to describe the parts of the eye.

  • Cornea: The Cornea is a transparent layer found in front of the eye.
  • Lens: Lens is the part which focuses the light into your eye.
  • Retina: The part where the light which is focused by the lens must fall so that he nerve cells can capture the image and send it to your brain.

One of the most common eye problems caused in people are:

  • Long Sightedness (Hyperopia).
  • Short Sightedness (Myopia).

Long Sightedness (Hyperopia):

Long Sightedness

Long Sightedness is a condition where the light which is focused by the lens does not fall on the retina but falls behind the retina. So the person has a blurred vision of the things which are nearer to him while he gets to see the things which are far clearer.

Long Sightedness also called as Hyperopia caused when the eye ball is tiny when the cornea is not properly curved and if the lens is thinner than it should be.

Hyperopia condition can affect adults who are above the age of 40. As we age, the muscles in our eyes weaken and cause long sightedness. Sometimes even babies are born with this condition, and you need to regularly have a check up to check if they have any issues.

Short Sightedness (Myopia):

Short Sightedness

Short Sightedness is a state where the light which is focused by the lens does not fall on the retina but falls in front of the retina. So the person has a blurred vision of the things which are far to him while he gets to see the things which are near to him more clearly.

Short Sightedness also called as myopia caused when the eye ball is very long when the cornea is curved too much and if the lens is thicker than it should be. Children or young adults get this short sightedness condition.

Both Myopia and hyperopia can be corrected by using concave and convex lenses as glasses and focusing the light directly on the retina.
