The light waves reflect of an object and hits the light-sensitive retina at the back of your eye. that's where cones comes in. cones are one type of photoreceptor, the tiny cells in the retina that respond to light    https://padlet.com/15barnsn/eyeformation/wish/129082145 2016-10-07 12:04:15 UTC https://padlet.com/15barnsn/eyeformation/wish/129082145 15loadee https://padlet.com/15barnsn/eyeformation/wish/129082664 colour blindness is usually a genetic condition that you inherit.

In fact, dogs are twice two times worse at differentiating between shades than humans are. Dogs only have two types of cones (like red-green colourblind humans), and this makes their colour vision very limited. https://padlet.com/15barnsn/eyeformation/wish/129448482 2016-10-10 09:40:44 UTC https://padlet.com/15barnsn/eyeformation/wish/129448482 15loadee https://padlet.com/15barnsn/eyeformation/wish/129450075 2016-10-10 09:48:24 UTC https://padlet.com/15barnsn/eyeformation/wish/129450075 Heterochromia iridum 15daniea2 https://padlet.com/15barnsn/eyeformation/wish/129450768 is when your eye has a combination of 2 colours.
