  • Eye Defects and Corrections
  • Care of the Eyes

Eye defects are conditions that can affect the function of the eye.

The common eye defects are:

  • Short-sightedness or Myopia
  • Long-sightedness or Hypermetropia
  • Astigmatism

Other eye defects include night blindness, conjunctivitis, cataracts, colour blindness, etc. These defects may be due to old age, bacterial infections, vitamin A deficiency, or poor hygiene habits.

1. Short-sightedness (Myopia):

Myopia is the medical name for short-sightedness, which means that people suffering from this defect can see objects that are near clearly but have difficulty seeing objects that are farther away. For example, if you’re short-sighted, you may not be able to make out highway signs until they’re just a few feet away.

This is because the eyeball becomes larger than normal. As a result, light from distant objects is brought to focus in front of the retina.
