$\begin{array}{cc}\text{Eye diseases}& \text{Defect}\\ \text{(1) Glaucoma}& \text{(A) an infection in the layer of the eye which causes inflammation}\\ \text{(2) Colour blindness}& \text{(B) increased pressure in the eye which causes damage to the optic nerve}\\ \text{(3) Conjunctivitis}& \text{(C) lens of the eye becomes opaque resulting in blindness}\\ \text{(4) Cataract}& \text{(D) inability to distinguish between colours due to defect in photoreceptors}\end{array}$

• A. 1 - B, 2 - D, 3 - C, 4 - A
• B. 1 - D, 2 - B, 3 - A, 4 - C
• C. 1 - B, 2 - D, 3 - A, 4 - C
• D. 1 - A, 2 - D, 3 - C, 4 - B

Answer 1

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.
