because working remotes ir lights will be visible in camera even though humans can’t see it .
- or the colour blindness image i uploaded (i got it from a meme sub so it isn’t reliable anymore) .
They’re based on color blindness tests. They work because the background and the numbers appear to be the same color, making the number indistinguishable from the background if you have that specific kind of color blindness.
What about the yellow one? It’s just a yellow circle. Right?
Yeah i was talking about the context that image was posted in . i edited the post to give more context .
Do you mean a simple audio or visual test that will test for diseases/ailments other than audio/visual issues? I’m not aware of any, and I doubt they exist. I’m not an expert though. I feel like most of the things mentioned in the meme don’t need a test, imo? Like as long as you’re in touch with your body and pay attention to what you intake these maladies should be easy to differentiate between.

I don’t know how much of a “tip” it is, but I like to use my cellphone’s camera as binoculars. Nowadays zooms can be very powerful and I use it regularly to read faraway signs, see details on distant structures and to see far things in general. The anti-shake software usually is enough, but if whatever I’m trying to read or look at is VERY far, I zoom in, hold my breath to snap a quick picture and then examine it calmly. I’ve found it to be very convenient, specially when traveling
They are based on real color blindness tests.
