What do we know about our vision in relation to light and luminous objects?

• We can see because light reflects off non-luminous objects into our eyes.

• We can see because light from luminous objects hits the back of our eyes.

• We can see because our eyes emit light that illuminates objects.

• We can see because light passes through objects into our eyes.

How does the light reach our eyes if the object is not luminous?

• The object emits its own light directly into our eyes.

• The light is reflected from the object into our eyes.

• The object absorbs all the light and nothing reaches our eyes.

• The light passes through the object to reach our eyes.
