why no one say pressure in eyeball different?

bonkysleuth SG

A fish out of water will experience blur images of the surrounding. Why is this so?

I think this is due to the refraction of the light and the refractive index or something. anyone has a clue?

fish out of water?

sEphIrOth SG

he is getting suffocated and is going to die Laughing

kaitokura SG

cos they are fish. Laughing easy wat

eagle SG

because the fish lack of air and gong3

^tamago^ SG

cos the retina of fish is adapted to the refractive index of light in water and not air, and vice versa for humans? Laughing

Not necessary, archer fish has good eyesight to shoot insects off tree branches.

eagle SG

i thought they shoot when eyes still underwater, while compensating for the refraction of light through water? TS is asking what happens when the fish eyes are out of water

oOprinceOo SG

when fishes are out of da water they die fast fast . eyes n etc i duno Laughing

ndmmxiaomayi SG

Since you know it's related to refractive index, then try to link lor.

Fish live in water, not land. Vice versa for humans.

The refractive index for air and water is different.

FrozernFire SG

they remain in water. it is said that the young ones have to practise before they get their almost perfect aim.

Herzog_Zwei SG

But the insect is out of water. Laughing

^tamago^ SG

Isn't it the same as how our primitive ancestors (and us) can train and practice how to spear a fish in water before getting it right? Laughing

eagle SG

but we are talking about fish out of water, not insects

No9 SG

I dun think got anything to do with refraction.
ITs just that the eyes of a fish are not suited for vision out of the water.
its the same as when u swim without goggles, can u see clearly?

^tamago^ SG

they contradict leh, unless u have an explanation on why it is not suited for vision out of water.

Zarks SG

That means the fish got great aura !! Smile Smile

wishboy SG

i think is becos fish's eyes can only see clearly in water
like a person with shortsightedness who wears specs

therefore if not in water will see blur blur
like a person with shortsightedness who dun wear specs

the fish's "specs" are the surrounding water Laughing

Bio or physic?

Bio --> the fish has a different eye which allow them to see underwater clearly and when out of water, the surrounding is different therefore it will become blur.

Physic --> The fish eye has a different eye with a different refractive index which allow them to see clearly under water and when they are out of water, the refractive index is change due to the density of the air...

Btw, i just guess de lol... Didnt study this before...
and also, who the hell care about fish? i only want to know why we underwater see blur blur de lol...
