Because of this we have blind spots, one for each eye. They are not usually noticeable because 1) the blind spot of one eye can usually be seen by the other, and 2) the brain fills in the gap.

So with this I will perform a magic trick, I will make your thumb disappear: Close your left eye and with your right look at a spot in the background, make a thumbs up gesture and place the tip of your thumb on that spot, move your thumb to the the right continuing to look at the spot in the background, when your thumb moves about 15 cm your thumb should disappear.

You can use your left eye too, just switch the directions.

I couldn't make it work. But I did notice that the spot in the background changed focus a tiny bit at one point. I suspect my brain was tracking the thumb and simply refused to continue to truely focus on the background spot. I tried and tried, but just couldn't make it happen. Neither eye. :(

Found the cephalopod

What is a "spot in the background"? Like where exactly

[-] InvalidName2@lemmy.zip 10 points 2 hours ago

It's way too late at night for all those directions, somehow ended up creating my own blind spot by sticking my thumb in my bum.

[-] tacosanonymous@mander.xyz 1 points 12 minutes ago

At least your dick didn’t get stuck in the toaster.

[-] diverging@piefed.social 6 points 2 hours ago

Well, I guess your thumb disappeared.

I can try another way the blind spot is about 15 cm at arms length to the right of the right eyes center of vision. So put your thumb there and it should disappear

This is one of many reasons the perfect eye argument by creationists is utter bullshit.

[-] themeatbridge@lemmy.world 61 points 3 hours ago

Ugh that drives me crazy. The human eye is a perfect example of observable evolution. Organisms exist with every stage of eye development, from a photosensitive spot to a more advanced convergent evolution of our eye. And the human eye is poorly designed for it's current use, resulting in a significant percentage of people requiring corrective lenses.

[-] floofloof@lemmy.ca 23 points 2 hours ago

It's a good example of evolving towards a local maximum then being unable to travel through a valley to a more optimal design. As such it confirms exactly what evolutionary theory would predict, and not what "intelligent design by an omniscient creator" would predict.

[-] Quill7513@slrpnk.net 29 points 3 hours ago

most of the dipshit "the eye is to perfect to have evolved" people also have cheap optics on their rifles. something to think about

[-] yumpsuit@lemmy.world 5 points 2 hours ago

You’re just jealous of GWOT surplus carry handle mounted AR optics because they remind you how evolution didn’t grace you with eyestalks 🐌

I wish i had eye stalks.

Clearly this means God’s chosen are the cephalopods.

[-] deus@lemmy.world 10 points 2 hours ago

In the lore of Lord of the Rings, it is said that the supreme being of that universe personally created both men and elves and since men were his favorite creations, he gave them the gift of... having pretty short lives (wow, thanks). Well, octopuses have a much shorter lifespan than us, so if our universe's creator is anything like the Middle Earth's then there's a good chance they are his favorites.

[-] roscoe@lemmy.dbzer0.com 5 points 51 minutes ago

It's been a while, so correct me if I'm wrong; but isn't the gift moving on to something else after a mortal life? If I recall correctly, elves are stuck in the physical world forever. Even when they die don't they just go to some limnal place for a while then come back?

[-] Confused_Emus@lemmy.dbzer0.com 3 points 26 minutes ago

Essentially, yeah.

Elves’ spirits either linger in Middle Earth or go to the Halls of Mandos in Aman. After some period of time, they can be re-embodied if they choose.

The souls of men did not linger, they were called to the Halls of Mandos upon death. Their souls would stay for a while in Mandos, separate from the elves, until they departed the Halls to only Eru knows where.

✅ Discount number of limbs

✅ Cheaply made eyeballs

✅ Held together with a bunch of inflexible bones

Wait, am I just an off-band octopus?

Damn.

More mindflayer propaganda.

(At a glance, this article needs some touching up and hasn't been meaningfully contributed to in some years.)

[-] SubArcticTundra@lemmy.ml 8 points 3 hours ago

Do I understand correctly that our ancestors had left the water before this upgrade dropped for fish?

[-] diverging@piefed.social 10 points 3 hours ago

I don't think you understand correctly. The cephalopod eye and the fish eye (which includes tetrapods) evolved independently.

[-] NounsAndWords@lemmy.world 7 points 3 hours ago

I've said it for years, as soon as it's commercially available I'm getting photoreceptors realignment surgery.

[-] errer@lemmy.world 5 points 3 hours ago

Is this something we could like, fix?

[-] Kalothar@lemmy.ca 5 points 2 hours ago

Uhhhh gonna say we could theoretically, but I imagine the brain has evolved a bunch of other subfuntions to make this work.

Though I bet you’d adjust super fast if it were only a visual change since our brains are great at adapting

[-] someguy3@lemmy.world 3 points 2 hours ago

Geordi eyes.
