How we can see ??

During the daytime, we can see things clearly. But we switch on the lights to see them at night. If we close our eyes we can't see anything even during day time or at night with lights on.

So let's see what are the requirements to take care of the "vision ".

         Now let's do the small activity 😊

1. Go to place with plenty of light.
2. Look at the tree in front .
3. Now, Now take a good look at the tree.
4.  Then, close your eyes & keep the body unchanged.
5. Can you see the same obersavations which you had when the eyes were opened. 

Even though you close your eyes, the tree still gets light. Then, 

why ??😮

didn’t you see the image of the tree you observed? Are your

eyes opened? Not just light to have a good view

The eye is important.

"The main factors which are needed to see are a source of light and the eye."
