Here's a question for 'intelligent designers'....?

If our eyes are intelligently designed, why is it that they all have a 'blind spot'? This is not a necessity in the construction of the optics of natural eyes - cephalopods (squid, octopuses and so on) have eyes which don't have a blind spot, so they have better vision than we do - couldn't the Designer have given us eyes that worked in the same way as these 'inferior designs' - Is it time for the Designer to go back to his workbench and come up with a better design - in fact, now that this has been pointed out, couldn't the Designer 'retrofit' us with version 2.0?

    The brain interpolates the blind spot based on surrounding detail and information from the other eye, so the blind spot is not normally perceived. With humans the eyes are overlaping as they percieve the same object, but with cephalopods they are not, so the needs of each are different, thus a different design.

    Some researchers estimate that people who can see well gain approximately 80 percent of their information about the world through their eyes. In combination with our brain, our eyes enable us to see in full color, to track moving objects and images smoothly, to recognize patterns and shapes, and to see in three dimensions. Furthermore, we can see in varying degrees of light.

    The latter involves a number of complementary mechanisms. For example, the pupil can expand from 0.06 inch to 0.3 inch (1.5 mm to 8 mm) in diameter, resulting in a possible 30-fold increase in the amount of light entering the eye. The light then passes through the lens, which focuses it onto the retina, concentrating the light energy by a factor of 100,000 times. So never look directly at the sun with the naked eye!

    The retina, in turn, houses two types of photoreceptors—cones (approximately 6 million), which give us color vision and high resolution, and rods (120-140 million), which are more than a thousand times as sensitive as the cones and help us to see in dim light. Indeed, under optimal conditions, a rod can detect a single photon, or elementary particle of light!

    Another adaptive mechanism involves retinal neurons linked to the cones and rods. These neurons adapt “in seconds and can improve night vision by a factor of 10 or more,” says the American Optometric Association. “Neural adaptation is rather like having low-speed and high-speed film simultaneously available in your camera.”

    Engineers often design cameras, scanners, and computers, along with compatible software. But the degree of integration and the level of sophistication attained are vastly inferior to those of our sensory system. Ask yourself, ‘Is it reasonable to attribute our vastly superior living sensory system to blind chance, as evolutionists do?’ An ancient servant of God named Job knew little about the human body compared with what we know today. Even so, he felt impelled to say to God: “Your own hands have shaped me.”—Job 10:8.

    Are trying reading "Strata" by means of Terry Pratchett. You'll see how historical your inspiration is. It is fiction about world-builders.....Even how they put fossils within the layers for men and women to seek out when they grew to be smart adequate. It is a hilarious e-book.

    Version 2 came up with Noah. Version 3 is coming up shortly. Just be patient. Sorry, I meant repentant.

    the 'blind spot' was intended

    my eyes work just fine with this so called 'blind spot'

    I don't why you have a problem with it
