How many Hz can a human eye see?

Your eyes can see up to 60 Hz!

This is an important fact to keep in mind when watching television or movies. The standard frame rate for televisions in the United States is 30 Hz, which means that the image on the screen flickers twice per second. This usually isn’t a problem, but it can cause headaches and eyestrain in some people.

If you’re watching something with a higher frame rate, such as a movie filmed at 48 fps or a show airing on one of the new high-definition channels, your eyes will be able to process the image more smoothly. So if you’re having trouble with eye strain while watching TV, try changing the channel to see if that makes a difference.
