Question

Which of the following are defects of vision?

• A. Myopia
• B. Colour blindness
• C. Night blindness
• D. Hypermetropia

Answer 1

Answer: (A), (D)

The two most common vision problems are:

1). Near-sightedness, also known as short-sightedness and myopia, is a condition of the eye where light focuses in front, instead of, on the retina. This causes distant objects to be blurry while close objects appear normal.

2). Far-sightedness, also known as hypermetropia, is a condition of the eye where light focuses behind, instead of, on the retina. This causes close objects to be blurry while far objects may appear normal.
