Question

How can we protect our eyes while looking at a strong source of light?

• A. By using a mirror
• B. By using reflective glasses.
• C. By looking through a glass
• D. By using paper

Answer 1

The correct option is B

By using reflective glasses.

Strong sources of light, like Sun, emit very intense light which can damage our eyes. In order to look at them, the intensity must be reduced to an appropriate level. This could be achieved by using partially reflective, partially transparent media.
Therefore, reflective glasses can be used to protect our eyes while looking at a strong source of light.
