How people protect eyes

People can protect their eyes by:

a. regular checkup by doctors, b. taking green and leafy vegetables in their diet, avoid reading while lying down, avoiding watching TV from very short distance, taking substantial sleeping and avoiding working for a long period of time in front of the computer or laptop.

Image of an object

It is the brain who corrects the image of the object and makes it visible for the eye.

Functions of ears

The main functions of the ears are as follows:

it captures the sound from the air and helps us in hearing,

they maintain the sense of balance

Eardrum

Eardrum is a very soft part of the ear and is very prone to damage. That is why; it is advised not to use any long object into the ear canal.

Odour particles

Every thing in this world produces odour particles but human nose can smell very few.

Nostrils

There is a lot of pollution in our environment. If they go directly into our lungs, it can damage it badly. That is why, small hairs in the nostrils filter out the air going inside our nose.
