What is the refresh rate/response time is ms for the human eye?

This is actually a good question. I had a similar one in mind. How Hi-Def does Hi-Def have to be before it shows us a greater resolution and response time then our eyes have the capability of processing? If we get the answer to this one, I’ll probably have the answer to mine.

Around 30 Hz for many people. Since an eye won’t be exactly in sync with a display, about 60 Hz is where people start not really telling there are frames involved. However on a CRT, the flicker of a lower rate can still cause more eye strain – personally, I like to try to have a CRT set for at least 100 Hz. Different people have different experiences and sensitivities, though, and the experience on an LCD is a bit different for the eye strain issue in particular.

@Zaku: I think he means what is the response time for our eyes.

Right asmonet. Sorry to hi-jack your thread here Windex.

What is the response time for the eyes. I have my monitor set at 100 Hz. What is the response time for my eyes? 400 Hz? 10000 Hz?

you know when you look at the specs for a computer monitor it always says something like
5ms or 7ms or 12 ms…

I’m not sure if my question makes sense, can you measure the human eye response time in milliseconds?

@bodyhead: no problem, the more knowledge we gain the better.

That is what I meant, too. Humans notice visual changes and distinguish smooth movement from teleportation at about 30–60 Hz. Which is somewhat greater that 12ms, but there are stages to the effects of lower frequency displays. First they just kind of seem flickery or ethereal and cause eye strain – that’s probably around 120 Hz, then at about 60 Hz or less most people may start to notice that motion in frames at that speed IS occurring in frames rather than being smooth continuous motion. It still looks like smooth motion down to about 30 Hz, but below 30 Hz, most people will notice it looks like moving images are jumping from place to place rather than passing through the space between, at least to some degree.

Fantastic. Nice answer Zaku.

Cheers. :-)

thanks!

That actually makes good sense. The response rate of my eye would have to be slightly lower then my monitor for me to think it is displaying a fluid picture when it’s just a series of still pictures.
