I think this is also a case of how good your screen is.

Depends on the screen too. Changing brightness makes things appear or disappear. Also, tilting the screen has the same issue.

This would be simple, but every computer and Tv screen has different contrast, pixels and brightness. I had to keep adjusting the screen just to see anything on some of them. In essence, this all depends on the display settings to be able to get this correctly. I ran the video again after changing the display settings on my computer and manage to get them all. Many were impossible on a old flat screen TV as the colors blended eliminating any shadows.

Quick nit pick: The line-length test is "cheese-able" because when the lines are different lengths, they are also different thicknesses. The larger line was simply scaled up compared to the original line, so it's a bit too easy to tell the difference even in the hardest image.

Blind person: interesting...

1:49 At this point I got overwhelmed and gave up until they said if u had normal vision it was random colors

A good monitor goes a long way here. Some of those full screen color ones towards the beginning were very hard, or didn't show anything on them at all... I noticed my screen actually fades 1 shade to another from one side to the other. Any shadow or shade difference on the left side (with the colors) didn't show. But my gamma is turned up so any black and white (grayscale) was very clear. It's more than 10 years old, so the fact it still works is good enough for me atm. The strawberry one were tricky, since you lied about the first pre-image, it actually was red/pink, not gray, because I went back and viewed it with the gray ones and it was not the same. Even the side (gray) bars had red in them. And either my monitor was off or the yellow one was yellow and not gray, since I could see the yellow pixels on my screen. And moving the image on behind bars made seeing it easier because I could see the pixel shift on the bars which made the image stand out. But this was fun, showed me I need a new monitor.

I got 21 and the funny thing is that I cleared the hardest stages easier than the easiest ones. 😂

11:07 It is a turtle. Tortoises have claws for tunnel digging. Turtles have webbed feet too.

purple & blue together was the most challenging, i have a really wonky astigmatism so i passed the 'line em up' & 'behind bars', they give me rainbow double vision literally.

18 on appearently a dirty screen, thanks for helping me notice it was dirt. Most I was fast on but the beige/orange it took longer to spot.

The biggest difference I would say is would be in the ‘size of your viewing screen’, I have the smaller iPad and in fullscreen mode a few times my eyes found it a little hard to focus but I managed to get 16. Mind you a few seconds longer also would’ve also helped.

This just really pissed me off and now I have a headache.... "can you find the animal the size of a pinhead on the neon yellow screen"?🤪FOH

I have bad eye sight but the ones with the animals, i can't see not a single one

Also depends on the position of the screen. For the stripe tests, the only time I got them wrong was when thye were numbers 1 or 10 (the left or right edge of the screen, due to the fading effect on the edges of a chromebook monitor). The moment I could see it wasn't 2 through 8, I just said "1 or 10", and it was.

That was Interesting, fun, & challenging too......👌👍 I was doing well with the first few but seemed to get a lot worse with the last 3. Fell down completely with the bars at the end, although I could never see the pictures in the background of the magic pictures which were popular a decade or so ago. (Passed a colour blindness test in the 90's using the first examples)

24:04 The gray is sort of a reddish brown tho, right? Except I look away for a minute, look back at the bars on either side (before looking at the strawberries) and can see gray. then I glance at the strawberries and the gray turns red/brown again 😳

0:54 "You should be able to see 74 however if you saw 21 you may have a degree of colorblindness" me: what if I saw 71?

My eyes felt too taxed to continue, but the memes and jokes pulled me through to the grand finale! Phew! Time for a cup of tea! Fun!

wait be amazed you do this now that's great keep up the good work with these videos and your other wans

To everyone getting mad and saying "this isn't a proper test", this video is for entertainment. Calm down your feelys.

28:29 "Is that a big juicy orange? Close, it's Donald Trump."

I passed "Behind Bars" by unfocusing my eyes to blur my vision. The shapes pop out when the lines are blurred away, so this test is one where people with blurry vision have an advantage.

I’ll have to try this again after my cataract surgery!

This is like the frequency hearing test that cuts out before reaching the highest pitch because of how KZfaq compresses audio.

0:00 yes my eyes are really good my ears not so much I’m actually in the process for an hearing aid so to compensate with shit hearing my eyes are amazing.

Most people don't have calibrated screens with accurate color reproduction and brightness levels. If they did, their scores would likely be a lot higher. But thanks for a fun test, I didn't keep a score tally (too lazy for that) but I fared rather well, likely because I have a decent calibrated screen (and I have good eye sight and color vision).

Was kinda curious how I’d do with my early stages of Stargardts Disease. I got a 7 out of 23. It’s hard to make out any of the hidden numbers or items in the pictures and I didn’t think I had issues with color blindness but apparently I do at least a little bit. Seriously though, eye health is very serious and if you are having any issues whatsoever no matter how minor it seems get it checked out. The sooner you get an exam the sooner you might get glasses or contacts to help correct and protect your vision.

The problem with the color tests is that they rely entirely on your monitor's calibration

the lines leangth one wasn't helped by the camera zooming in or out of the image but i still got perfect

Yeah, graphics settings on my PC must make this abnormally hard for some images. Some of the color ones I couldn't even see when they were pointed out and I know I have good vision because I've been tested.

The whole point is to practice until you can see the things. Better screen/phone helps. Moving your head along any axis relative to the screen helps. Rotating your head helps. Somehow, yawning occasionally helps. Most importantly, you can use all these tricks along with diet/exercise/sunlight/outdoor air/being around people to see objects better IRL. Keep working on it until you improve, and if your eyes change, go to a good eye doctor to update (i.e. downgrade) your glasses to a less powerful prescription! Maybe someday you'll see amazingly IRL with NO glasses! FWIW I got less than 11 points my first time through, but I'm going to practice every day until I understand all the tricks and internalize them!

My sight is now gotten worse than it was before hahahah

“Good job if you got 15, but if got you 17” Me who got 16: •-•”

You have to have a correctly true color set monitor, which I do not have. I set it for the most appealing view for me.

11:37 you sneaky

“Ok you can stop squinting now” Me: how did you know

Fun Fact: This isn't meant to be seen on your tiny phone.

Interestingly, I have vertical astigmatism in both eyes, and I had a hard time with the second stage of the behind-bars test. I made out the Apple and WWF logos, and Mickey just fine, but I couldn't even see Trump or the cat. But I tried it a second time with the video rotated 90 degrees (full screen on my phone, then holding the phone upright). I could make out all of the images very clearly because of the blurring from the now horizontal lines.

At the beginning of video: if you saw 45 you might be color blind Me who saw 7: 👁️👄👁️

I have learned over the years that the only way I am able to see some of these illusions, is to literallly make myself go crosseyed

I decided to give a try even if I know I’m colourblind. I still could get many points, because I could see the answers in almost all stages 1 and 2, except for the balls in the lines and the strawberries for sure ! I could also get stage 3 points in some exercises that were not to much linked with colours. Fun fact about colourblindness: when it’s a matter of darker/lighter, we can sometimes manage it better than people with regular colour vision. And a suggestion : when you prepare such tests, please always tell the answer. I would have loved to know the colour of the different strawberries, but often you just put bars of the same colour around and I couldn’t tell what colour they were !

Well it’s been 2 years since I did this 😹😹 I had forgotten I had done it before, but nothing has changed at all, I think I but it down to the fact I work with seed beads and other extra small detailed things. I still got all 23😳 now I feel a little bit of an odd ball. I thought age would have played a big roll in this so I was surprised at the age of 60 I still could see them.

On the color that what is different one I HAVE GREAT EYES!

This is more important than school

The trick is to move the screen around to make the picture easier to see, for those who don't know.

Before beginning the video, I saw the cat's eyes and could make out the right ear and top of head outline. I scored in the 15 - 20 range (18). The shades were most difficult. The bars were easy. The colours no problem - I was tested for colour blindness for work eligibility around 1972.

I scored 15. In some categories I only missed 1 or 2 panels, but could not score a point because I didn’t correctly answer all of the panels. Still I think that’s pretty good as I’m blind in one eye and lack depth perception. I had the most difficulty with the strawberries and distinguishing the same/different lines. Fun test though. 👏

11:57 The camel on my screen is literally a square how do you guess that

For the colour blind test I saw 71 lol does that make me partially colour blind or maybe it’s night shift on my screen making it more orange

I genuinely didnt see any of the animal ones except the elephant, I also missed all of the solid colored number ones. Skipped the bars as that one hurt my eyes and almost gave me an instant headache. I cant tell if im bad at this, my monitors color accuracy/correction is terrible or i have some form of color blindness lol.

Aghh! I only got 18 in spite of being an artist. Also, my monitor resolution is a respectable 3840 x 2160 or 4K. The only excuse I have is diminishing eyesight as I am 70+. But still, I should have done better. One's results would vary quite a bit depending on your monitor and how you have it calibrated. I think for most people to get an accurate assessment the test would have to be given in real time using printed materials. Fun experiment all the same.

The moment you realised you failed the previous stage but passed the stage after that

Damnit, I know I’m mint-purple color blind already!

That was fun!! 😃 Thank you!! 😊❤❤

Probably because I'm using a phone I couldn't see the animal silhouettes at all. I generally have very acute colour vision though. I had bilateral cataract surgery in 2010 so my colour vision improved significantly. I was astonished to discover that some of my clothes were nothing like the colour I thought. My father was a researcher in colour perception in art so I knew what had happened and why. I'm now 75. ps: I just tried again taking my glasses off and holding my phone at arm's length. By putting the images out of focus I could see them.

Him: aw what a cute bunny Me: THAT'S A DAMN GIRRAFFE

I already know I have problems with it, but I scored pitifully on the neon colors. I have never been able to see Neon's right... that was literally why I lost the few points I did. Everything was just so freaking bright lol. The static one you said was "hard" was a joke. I'm awesome with detail! (just those damn neons that make your freaking eyes bleed!) Elite eyes. :D

A couple things that can also make this hard. Brightness of the screen and the tint level. I bet if we placed these all on cards where our monitors were out of the equation, many of us would do even better at this.

I wonder how accurate those tests are. considering that color blindness comes from variations in how we perceive brightness, contrast and saturation. And we also know that those online tests are not that accurate as an actual test. Why? How many people have set their monitors up so that the colors eminated from it are true to how we see colors when we walk outside?

10:16 these were the hardests for me. I could see too much shapes at all in the different colors, except the bluish colors. I was playing honestly, and with those tiny fails, it was 9 for me. This was so interesting. But this definitely should be tested on paper

0:57 BE AMAZED: you should see 74 Me who saw 81: mama I need glasses

These illusions are so tricky ❤

i got a 17 there mostly because of the "color Count" stage 3, the "strawberry test" and i mist the small pig to right corner on the last stage of "Animal instincts"

18:48 “night” wasn’t the first thing I saw...

This was fun. I had a difficult time with the flat colors with the hidden numbers. Did well with the static background and numbers, but not the ones before. Makes me wonder how bad my eyes are.

LOL 1:40 I was like "WTF am I looking at? That's no number I know of."

The points system I didn't understand how I got some right and the maximum correct is only 23. I wear glasses and I didn't like the too much bright colors filling my screen as the tests of the fifth part of Color Count, Animal Instincts, first part of Crunching the Numbers, & Word Games. I still enjoyed it because ophthalmologists shine bright light into the eyeball.

me doing this in a dark room and thinking I'm blind, but then with light on and me seeing everything in lvl 3

This video really helped me to actually make an appointment with my eye doctor and turns out, I need glasses! Thank you for this video, I would have never known! :)

I LOVE YOUR VIDEOS

I stopped this about 25% of the way through, for the simple reason that most home monitors or computer-compatible televisions have nowhere near the continuity to conduct a true color test... negating the value of this somewhat lengthy test. For these to be truly valid they would have to be on color-absolute cards with consistent and correct room lighting. I have excellent color perceptions but some of these screens looked absolutely identical on my monitor... and tones would even change on the monitor. This is just a "fun exercise" (maybe) that no one should take it seriously.

Me as a cat lover : **shakes my head** Also me : Awwwwwwwwwwwwwwww Sister : yo mom, I think jenny is crazy

My eyes be like: it’s my time to shine. Who else has great eyesight?

10 I got only one of the strawberry ones. When the answers was revealed, I still didn't know what colour they were

I see it, it has its eyes wide open and the cat is a little to the left

In the thumbnail... I could see the cat, when I blurred my vision! This guy should be rewarded for the most attractive thumbnails of all time. Where do you even come up with these ideas? Edit: I could fine all of the colours, so I do not have to go to the doctor to get sight checked... Lol, you don't even need to go to the doctor for the sight. You can tell how good you vision is here, right in this video! Well, I will agree the last level was kinda hard to guess, but... I only lost to the colour blue because, I had less time to think and guess.

These tests made my brain hurt. I was diagnosed as colorblind by my optometrist several years ago, but this was just too much for me.

My eyes is playing trick with me 6:42

“When your colorblind but get them all right”

I scored an 8, and was frustrated when the images zoomed in slowly. That made it way harder for some tests.

Eyes are very important for everything!!!

on the first light blue color count test I found it really hard to see the lighter color.

And the angling, it helped a lot.

Well I had under 10 point. Now the real question: were it my eyes or my monitor? 🤔

Idk why but any thing in green or blue was not visible for me even in the normal levels... And one more thing....the stages you said were hard went easy for me but the easy ones were hard..😅😅

144 quality is the only one I can afford 😭

Without looking at the comment section, the numbers I see in the thumbnail are: Left - 4 Middle - 6 Right - 4

These guys didn't account for the fact that after each one the thing they just highlighted will leave a solid mark on your vision, interfering in the next one. I failed pretty much all the fine distinguishing ones- the animals, numbers, words, because of that. And I just got new glasses, so my screen may be not so great.

The one where you had to see which ball was tthe odd one out was really easy for sum reason

I feel like my screen was a bit TOO bright, but I still managed 13 points. I feel like I should have gotten way more though, seeing as, in several parts, I only failed one test, usually that being the first or last.

It seemed to get easier the harder the stages were and I wouldn't be surprised if a lot of people thought the same thing

They are cheating by making some of the animals so damn small.

23:07 you said it was same but i used a ruler and the top one was bigger

The first one is really easy to do!

Narrator: "You should be able to see a big red button...." Me: Nah, Its grey.

Fun fact: you don't need perfect colour vision to get a good score on this test! I'm blue-yellow colourblind, but I still got 18. Don't remember where four of those points went, but one was on the strawberries.

I got 10. I noticed I did specifically poorly on all the ones involving blue backgrounds. This difference between a blue question and a yellow one was vast even within the same tier difficulty. Is it a monitor issue or is this a thing everyone's experiencing? Either way, I definitely wouldn't have gotten a perfect score even if that was a fixable issue.

If I did not count the animal instincts stage, I would have only missed seven total out of all of these tests. I have separation between my screen protector and my tablet that was causing blobs to appear that were very distracting and it screwed me out of catching almost all of the images in the animal instincts, but I literally only missed seven total items out of all of the other tests combined. I guess I got lucky eyesight because I am drunk right now and I guess I still did pretty good lol

Be aware that the video quality matters :'3
