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.

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.

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 😳

0:00 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.

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

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.

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.

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.

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

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

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

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)

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.
