Perfect design ? Human Eye
The human retina is installed backwards the light sensing cells face the back of the head and the nerves that carry the signal sin on the top of them , blocking some light these nerves bundle together to punchh a hole through retina to get to the brain creating a blind spot
(Octopus has eyes where the nerves are behind the retina, so there's no blind spot )
1. Blind spot The optic nerve exits through the retina, creating a blind spot where no photoreceptors exist. A perfct camera would not have a missing data zone, and that's why the camera is a perfect design
2. Retina wired backward Light must pass through layers of nerves and blood vessels before reaching photoreceptors, reducing clarity and increasing distortion.
3. Blood vessels block incoming light Retinal blood vessels sit in front of photoreceptors, casting microscopic shadows and lowering signal quality.
4. Limited spectral range Humans only see a tiny fraction of the electromagnetic spectrum. Many animals see ultraviolet or infrared.
5. Chromatic aberration Different wavelengths focus at slightly different depths, causing subtle color fringes and reducing sharpness.
6. Poor night vision Humans are extremely bad at seeing in low light compared to nocturnal animals.
7. Floaters Debris in the vitreous humor drifts across vision, visible as shadows, with no functional benefit.
8. Retinal detachment vulnerability The retina is loosely attached and can detach, causing blindness, a major structural weakness.
9. Glaucoma risk due to poor drainage Eye pressure can increase and destroy the optic nerve because fluid drainage is inefficient.
10. Macula dependence High resolution exists only in a tiny central region; most of the visual field is low resolution.
11. Aging lens stiffening The lens loses flexibility with age (presbyopia), making near vision progressively worse.
12. Easily damaged photoreceptors Light itself slowly damages rods and cones over time.
13. Inverted image correction required by the brain The eye forms images upside down, and the brain must computationally fix them
14. Susceptibility to refractive errors Myopia, hyperopia, and astigmatism are extremely common, showing calibration instability.
15. No self-repair for neural damage Once retinal neurons die, they do not regenerate.
16. Uneven color sensitivity The distribution of cone cells is irregular, creating minor distortions in color perception.
17. Tear film instability Dry eyes are common because lubrication is fragile and easily disrupted.
18. Narrow dynamic range Eyes cannot handle very bright and very dark scenes simultaneously like modern cameras can.
19. Poor edge resolution Peripheral vision is blurry and color-poor, even though threats often appear there.
20. Susceptibility to optical illusions The visual system is easily fooled, showing it is not optimized for objective accuracy.
