Why do lions have better eye sight at night time then humans?

Lions have an eyesight that is very similar to a cats. The retina is much more sensitve in a lions eye so it detect light better. They also have something called 'rods' in their eye which are very sensitive to small amounts of light and allow animals to see in poor light conditions. But this normally means they cannot detect colour. There is a higher proportion of rods in animals with good night vision (noctunal animals).
