Dulcie’s Days 4

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.

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.
