Sometimes you remember a vivid picture of a dream you saw. What is the role of your eyes in this experience? |
|
Answer» If we look at a bright object and then close our eyes, the sensation of light persists for a short period. This is known as persistence image or the after image. It lasts for one-tenth of a second. Therefore by closing the eyes and gently pressing them with your palms, you see some specs of brilliant light. |
