Answer 2

Among myopia, hypermetropia, xerophthalmia, astigmatism the ‘odd one out’ is the xerophthalmis.

The others deal with problems in the eyesight such as blurred vision, near sight, long sight, etc, whereas xerophthalmia deals with abnormal dryness of the conjunctiva and the ‘cornea’ of the eye leading to inflammation, it is majorly a condition caused bu vitamin A deficiency. This causes abnormal thickening of the conjunctiva and can lead to corneal ulceration.
