Answers:
The 3 main ones are:
1. Myopia a.k.a Short Sightedness: The person is only able to see nearby objects. The most common type of ailment in young adults.
2. Hypermetropia a.k.a Long Sightedness: The person is only able to see faraway objects and nearby objects appear blurred.
3. Presbyopia : This is a condition which affects everyone at a certain age. As the person ages, the focussing power of the eyelens diminishes due to the weakening of the ciliary muscles. As a result the person has difficulty in focussing clearly. for e.g. old people normally have to hold a book at a distance while reading to see clearly
