Solution

The correct option is C 1 - B, 2 - D, 3 - A, 4 - C
1) Glaucoma - a condition in which the reabsorption of aqueous humour by blood does not occur causing an increase in pressure within the eye which can cause damage to retina and optic nerve.

2) Colour blindness - a condition in which a defect in the cone cells leads to inability in distinguishing between colours such as red and green.

3) Conjunctivitis - a condition in which the conjunctiva of the eye gets infected, causing it to swell.

4) Cataract - a condition in which the lens of the eye becomes cloudy and opaque, resulting in partial or total blindness.
