And the simple explanation is that the eye is actually very simple to explain in terms of evolution. Mutations developed light-sensitive cells in simple organisms. Those light-senstive cells gave those organisms an advantage in sensory abilities. Eventually nerve structures develop and physical changes occur to focus light into portions of those structures prove beneficial.
Is a easier way to visualize this process through this diagram which shows different levels of development between mollusks. Note a simple change like the closing of tissue around a small opening creates a pin-hole camera effect.
