DESCRIPTION:An animal invests resources in an eye’s optics and photorece
 ptor array to meet behavioural needs economically. Thus eyes are adapted t
 o meet these needs using designs that inspire physicists and engineers and
  provide opportunities for biologists to discover how complicated organs e
 volve. We take a new look at eye design by asking a question that is commo
 nplace in engineering\, but has not been addressed by biologists\; how sho
 uld the space\, materials and energy invested in an eye be allocated to op
 tics and photoreceptor array? To provide answers we develop a new cost:ben
 efit approach that uses optical\, geometrical and physiological constraint
 s to link investments to an eye’s ability to capture information from li
 ght. Our models and data analysis show that eyes are configured efficientl
 y. Photoreceptor costs dominate and influence the structure of the entire 
 eye by competing with optics for resources.
