Welcome to class, I hope you enjoyed the last class. Today we will be talking about the care of the eyes. Follow me closely and you will understand what we are about to talk about.
Every person has five sense organs. These are the eyes for seeing, nose for smelling, ear for hearing, skin for feeling and tongue for tasting. These sense organs are very important for a normal life. They also affect the appearance of individuals. These organs therefore require care.
Parts of the Eyes
- Eyebrow: Prevent sweat from running down into the eyes.
- Eye lashes: Prevents the eyes from dust and dirt.
- Eye lids: Can close to protect the eye from foreign objects.
- Eye balls: They are the organs of sight. Each is connected to the brain by the sensory nerves called optical nerve.
- Cornea: A protective layer. It keeps dust and dirt from passing through into the pupil of the eye.
- Iris: It is the coloured part of the eye. It surrounds the pupil. It can increase or decrease the size of the pupil.
- Pupil: The hole in front of the eyeball through which light ray passes into the eyes.
