In the future, would a robotic eye see in higher resolution than a normal eye?

A robotic eye already sees more bandwidth than your eye. Take your IR TV controller and look at the LED's while playing with the buttons. Now look at it with your cell phone camera. You can see IR with any digital camera. It can also see UV. Your eye cannot see these.

Yes, the brain takes time and energy to process the signals it receives via complex biochemical neurological pathways. It is essentially a computer (the brain), and even though it is incredible it has many limitations that are easily observable.

AS FOR NOW, WITH MANY SPECIAL LENS AND SENSORS SET, SPECIAL MADE ROBOT EYE SIGHT CAN SEE MUSH BETTER THE HUMAN EYE.

WITH THEM, IT CAN SEE IMAGE IN X-RAY, GAMA RAY, UV, IR, FULL COLOR LIGHT AND MICROWAVE ( RADAR IMAGE ) .
