Question

A person wears convex lenses for proper vision. Without glasses the image of the object is produced

• A. On blind spot
• B. On yellow spot
• C. In front of retina
• D. Behind the retina

Answer 1

The correct option is D Behind the retina

Convex lens converge the light rays and decrease the focal length. Hence, if the person wears convex lens for proper vision, this means he needs convex lens to focus the light rays on the retina which are otherwise focussing behind the retina. This shows that the person might be suffering from myopia in which image is formed behind the retina and it is corrected using convex lens.

Therefore, without glasses, the image of the object is produced behind the retina.

So, the correct answer is 'Behind the retina'.
