The eye is a very delicate organ. It is made up of complex structures and optical systems that enable us to see the world. It helps to focus the light into a point focus, which enables us to see objects around us.<\/p>\n
So what parts are our eyes made up of?<\/p>\n
Structure of eyes<\/h2>\n\n
Eyelid<\/h3>\n
\n
The external part of the eye that covers the eyeball and protects it from dust and injuries. The eyelashes trap dirt and debris from coming into contact with the eyeball.<\/li>\n
Blinking facilitates proper spread of the tear film on the ocular surface thus keeps the eyes hydrated.<\/li><\/ul> \n
Pupil<\/h3>\n
\n
Is the opening in our iris which regulates the amount of light entering the eye, similar to a camera aperture.<\/li>\n
Pupil becomes smaller in bright light to reduce the amount of light entering the eye, and it becomes bigger in low light enabling us to see better.<\/li>\n <\/ul> \n
Sclera<\/h3>\n
\n
It is the outer, white protective layer of the eye.<\/li>\n
It gives support to the internal ocular structures and also serves as an attachment for the eye muscles.<\/li>\n<\/ul> \n\n
Iris<\/h3>\n
\n
This is the coloured part of the eye. It contain different pigments which impart different shades to our eyes.<\/li>\n
The pupil is present at the centre of the iris which acts as a regulator of light<\/li>\n<\/ul> \n\n
Cornea<\/h3>\n
\n
It is the clear structure that is present in the front of the eye.<\/li>\n
It allows the light to enter the eye and protects the internal structures.<\/li>\n
