Your eyes are amazing and very special. Some people have blue eyes others have brown eyes. Some people have green, almost black or a mixture of the colours just mentioned. When the sun is bright or if you look into a bright lamp your pupil becomes smaller. When you are in the dark your pupil is larger to help you see better. The pupil is the black part in the centre of your eye. The coloured part is called the iris. Your eye lashes help stop dust and tiny particles that float in the air from entering your eyes. Blinking keeps your eyes moist, that means it stops them from drying out and becoming prickly and sore.
