"cats have a visual field that spans a whopping 200 degrees, as compared to 180 degrees in humans"

I disagree with this. Firstly, I tested my own vision and I have 220 degrees. Secondly, I always find my cats looking straight at me or whatever they want to examine, they don't seem to be able to see sideways, and the other day I walked over to one cat, I was 90 degrees from his forward direction, and he didn't see me until I touched him to stroke him, which scared the hell out of him.

What are your experiences of cats vision (and your own)?

degrees.

Yeah, mine is much wider than most peoples' too.

Secondly, I always find my cats looking straight at me or whatever they

That's a different question. I look directly at what
I want to focus on, but that doesnt mean that I
dont notice movement out of the corner of my eyes.

Yeah, that's a much better test of that field of vision question.

Bur its likely that some cats have a form of tunnel
vision too. We know that young kids to, that's why
they can get run over when crossing the road.

What are your experiences of cats vision

I dont remember actually testing that with any of the cats
I had and I dont currently have any cats that I can test.

(and your own)?

Like I said, mine is much wider than most people.

I used to get an effect where I could get false vision
out of the corner of my eye when very short of sleep,
think I see movement but when I turn to check there
isnt any movement there. Dont get that effect anymore.

I don't believe you. They have the same vision, they just don't pay attention and are preoccupied with things they consider more important. I remember us testing our eyesight in primary school for a game/lesson, and it was similar then.

Not easy to persuade a cat to look at something else while you're doing something interesting. I guess if one person distracted it maybe, but then you wouldn't know if it saw the second person to the side. You'd need something it wanted to look at, then something even more exciting than that like it's favourite treat.

A minister gave a talk to the Lions Club on sex. When he got home, he couldn't tell his wife that he had spoken on sex, so he said he had discussed horseback riding with the members.
A few days later, she ran into some men at the shopping center and they complimented her on the speech her husband had made.
She said, "Yes, I heard. I was surprised about the subject matter, as he's only tried it twice. The first time he got so sore he could hardly walk, and the second time he fell off."

Fact.

"Newborn babies have peripheral vision" -
http://www.aao.org/eye-health/tips-p...on-development

Irrelevant to whether younger kids have a narrower field of view than when
they get older.

"Overall there was little evidence to support the hypothesis that children
have poorer peripheral vision than adults relative to their foveal
vision." - http://www.ncbi.nlm.nih.gov/pubmed/3801789

Pity about the other studys that show they do have.

"Generally, if a baby

We aren't talking about babys.

is not tracking motion across their full range of vision by 3 months of
age, parents should consult their pediatrician."

That has nothing to do with why kids get run over.

- http://everydaylife.globalpost.com/p...ers-44127.html

Wrong with peripheral vision.

They have the same vision, they just don't pay attention and are
preoccupied with things they consider more important.

Wrong.

Doesnt mean that you always had the same
amount of peripheral vision when a young child.

You clearly didnt if you concluded that all kids

Cats get cateracts and some conditions make the side vision worse which is

I disagree with this. Firstly, I tested my own vision and I have 220 degrees.

It's difficult to test yourself, have you ever tried tickling yourself ?.

The human eye only looks at about 15% of it's view it sort of scans and reports back to the brain.

Cats are better at seeing changes or fast movemnt rather than gradual changes which they dont normally worry about.



Secondly, I always find my cats looking straight at me or whatever they want to examine,

same for most creatures, as the cnetre of the eye is usually the the best for general viewing.
Have you ever noticed that some bulbs flicker out of the corner of your eye but not when you look directly at them.

Sometimes it sees a small fly or perhaps it hears it but it's following something I just can't see myself.
Cat was on my lap the other night and sudeetnly she started staring strangly at the window I tought it was something on the TV, but no it was a bird on the TV areal across the road through the net curtains, maybe some refelction or something made her suddently look up, but all I could see was a bird on a TV areail which didn;t hold my inerest but held hers for nearly 2 mins then she went back to sleep.

same for most creatures, as the cnetre of the eye is usually the the best for general viewing.

Yes, but you don't stare directly at a person for more than a second or two. It doesn't take long to gather the details you need.

Have you ever noticed that some bulbs flicker out of the corner of your eye but not when you look directly at them.

All LED car tail-lights flicker out of the corner of your eye, and half of them when you're looking straight at them. Hard to believe in the 21st century we get such ****ty lights (and on decent cars).

they don't seem to be able to see sideways, and the other day I walked over to one cat, I was 90 degrees from his forward direction, and he didn't see me until I touched him to stroke him, which scared the hell out of him.

Maybe he was day dreaming.

He was licking his leg.

What are your experiences of cats vision (and your own)?

Sometimes it sees a small fly or perhaps it hears it but it's following something I just can't see myself.
Cat was on my lap the other night and sudeetnly she started staring strangly at the window I tought it was something on the TV, but no it was a bird on the TV areal across the road through the net curtains, maybe some refelction or something made her suddently look up, but all I could see was a bird on a TV areail which didn;t hold my inerest but held hers for nearly 2 mins then she went back to sleep.

It's a simple life.

No it's not all women, just some. And I don't see how four cones helps anyway. What's the point in having one inbetween two others? You can sense any colour between those two receptors by the brain analysing the strength of the signal from each receptor. Which is why we don't see three colours, but an infinite number.

https://en.wikipedia.org/wiki/Tetrachromacy

"In humans, two cone cell pigment genes are present on the X chromosome: the classical type 2 opsin genes OPN1MW and OPN1MW2. It has been suggested that humans with two X chromosomes could possess multiple cone cell pigments, perhaps born as full tetrachromats who have four simultaneously functioning kinds of cone cells, each type with a specific pattern of responsiveness to different wavelengths of light in the range of the visible spectrum.[16] One study suggested that 2€“3% of the world's women might have the type of fourth cone whose sensitivity peak is between the standard red and green cones, giving, theoretically, a significant increase in color differentiation.[17] Another study suggests that as many as 50% of women and 8% of men may have four photopigments and corresponding increased chromatic discrimination compared to trichromats.[16] In 2010, after 20 years of study of women with four types of cones (non-functional tetrachromats), neuroscientist Dr. Gabriele Jordan
identified a woman (subject cDa29) who could detect a greater variety of colors than trichromats could, corresponding with a functional tetrachromat (or true tetrachromat).[18][19] Apes, Old World monkeys, and Humans normally have three types of cone cells and are therefore trichromats. However, at low light intensities, the rod cells may contribute to color vision, giving a small region of tetrachromacy in the color space;[20] human rod cells' sensitivity is greatest at a blueish-green wavelength."

It's difficult to test yourself, have you ever tried tickling yourself ?.

Those are not comparable.

But similar ideas.

What makes you think you can't test yourself? You know the way you're looking, and you know where the thing is you're trying to see.

Tickling, **** knows, that doesn't make sense.

Cats are better at seeing changes or fast movemnt rather than gradual changes which they dont normally worry about.

That cat always worries about me.

So is used to you.

And should have run away as I approached. Even if it wasn't scared of me, it should have noticed I was reaching over to stroke him, and not jump out of his skin when I touched him.

In general women see more colours or rather have a beter perception of shades.

And I don't see how four cones helps anyway.

What you 'see' doesn't matter.
Facts will out-weigh what you see or think.

yes that's the problem yuo are aware that something will become visible out of the corner of you eye and that is the problem.


Tickling, **** knows, that doesn't make sense.

you mean it doesn't to you.

Why ?

Even if it wasn't scared of me, it should have noticed I was reaching over to stroke him, and not jump out of his skin when I touched him.

Why did he jump out of his skin. Think about this.

Now this is why you can't test yourself.
If the cat would have been testing himself he would have known when he was going to stroke himself wouldn;t he but he didn;t know when you were going to stroke him see how simple this is.

I don't move my head backwards forward and sideways or up and down while doing the dishes.

One can also see violet which is outside of the blue receptor peak. Blue light activates the blue receptor and to some extent the green one, violet only activates the blue one and the brain interprets it as violet.
