Our eyes are a very important part of our face. Apart from seeing with them, they often show how we feel within us. When we laugh, our eyes laugh with us, but when we are sad our eyes cloud up with tears. It is therefore necessary to take good care of the eyes.
Structure of the Eye
The eye consists of many parts and each part performs different functions. If we understand each part, it will help us to know how the eye functions and how to care for it. Many parts of the eye are hidden and so cannot be seen.
The eye is made up of the following parts: eyelids
i. Eye balls
ii. Eye lashes
ix. Aqueous humour
x. Vitreous humour
xi. Tear gland.

The pupil helps to control the amount of light that enters the eye.

This functions to maintain the ability of the pupil to control the amount of light that enters into the eye.
It prevents dust and dirt from passing through the pupil of the eye.
The retina forms the image of an object in the eye.
The Tear glands:
They help to produce tears in the eye which carries any foreign substance that has entered the eye along with them. They cause tears to flow out when one is crying.

Equipment and Materials for Eye care
Cosmetics are usually used for caring for the eye. They include: eyeliners or kohI/tiro, eye pencil, eye shadow and mascara.
Procedure for Care of the Eye
There are two methods for the care of the eye. They are:
a. The traditional method; and
b. The modern method.
The Traditional Method
This is a method used by ladies in the rural areas for their eye make-up. This method involves the use of eyeliner in form of kohl, used mostly by old women in the rural areas. Kohl or tiro is usually powdery and used to darken areas around the eyes. It is usually stored in little leather or metal container. It is applied with a little metallic stick, and it is still in use in many rural communities.
The Modern Method
The method of eye make-up practised today in Nigeria was initially brought to the country by those who travelled abroad and returned with them. It involves the use of eye shadows, mascara, and eyeliners to make the face look attractive.
Eye shadows come in different forms. They can be in the form of a pencil or powder. Eye make-up should be applied in the right amount in order not to look funny.
Prevention and Control of Eye Problems
Treat the eyes with care. In doing so, you should always obey the following rules:
1. When you are reading or sewing, make sure you hold your book, sewing or other handwork materials in such a way that it is not too near or too far from your eyes.
2. You should also make sure that you always use light that is neither too bright nor too dull.
3. Sometimes, the sun is very bright and we need to protect our eyes with sunglasses which have dark lenses.
