• That little pink bit in the corner of your eye is what whats left of a third eye lid our ancestors in the ocean had.

• Van Gogh had cataracts and that's why his paintings had a lot of blue in them

                                               

•  The human eye can distinguish between nearly 500 shades of grey not just 50.

• Babies don't actually produce tears until they are about three months old. 

• The biggest eye on the planet is about the size of a watermelon and belongs to a giant squid.

• The muscles in your eyes are comparatively the strongest in your body for the job they do.
