In the human eye there are rods and cones that have different jobs
Dulcie’s Days 3
Rods
» See in black, white and shades of grey.» Tell us the shape that something has.» They detect movement first.» They are super-sensitive, allowing us to
see when it’s very dark.
Dulcie’s Days 4
Cones
» Work best in bright daylight.» They allow people to see colours and fine detail.» Cones are divided into three different types – red, green
and blue to help you see different ranges of colour.» Together these cones sense combinations of light waves
that enable our eyes to see millions of colours.
