Originally Answered: Is 240hz visible to the human eye? It is possible to strobe a light at 240 Hz and if you look at a fast moving object, you will see the object “frozen” at a number of different positions. Absent a strobe effect, the eye can see changes (flicker) in the 60 to 75 hertz range.

Do you blink less with glasses?
