How Good Are Your Eyes?

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. 😂

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: •-•”

So i think i just found out I'm color blind

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.

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

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.

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

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.

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?

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

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

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.
