How does light affect the human eye?

This week we are looking at the human eye and it’s features as part of our light topic. We discovered that the human eye is able to reduce or increase  the amount of light that enters it. It does this using the iris. We also found out that the image flips upside down and the brain has to turn it back again. how clever!
In addition we used a simple trick to find our blind spot in our eye!
Next week we’ll look at refraction using water!
