The human eye can perceive up to 1000 frames per second according to recent studies by visual neuroscience researchers at MIT. However, in practice, the maximum number of frames the human eye can process is highly dependent on the context. For example, when watching a movie, most people cannot distinguish the difference between 24 frames per second (fps) and 30 fps, while when playing video games, the minimum accepted fps is around 60 fps.
Why
The fps limit of the human eye is limited by the frequency of the brain’s ability to process visual information, called the Critical Flicker Fusion (CFF). The CFF is dependent on a range of factors including luminance and individual variability.
Or
In situations where the visual stimulus is too fast for our eyes to perceive, we perceive the event as a blur or a single continuous image. For example, when watching a car race, the movement of the cars will appear as a blur beyond a certain speed.
Currently
The relationship between fps and the human eye is an area of active research, particularly in the field of virtual or augmented reality, where high fps rates are crucial for an immersive experience.
Who
In addition to visual neuroscience researchers at MIT, other researchers exploring the human eye’s fps capabilities include optometrists and psychologists.
Additional questions and answers:
-
- Q: What is the relationship between fps and motion sickness
-
- A: Lower fps rates, particularly below 30 fps, can cause motion sickness for some people due to a lack of visual information to properly process motion direction and speed.

- A: Lower fps rates, particularly below 30 fps, can cause motion sickness for some people due to a lack of visual information to properly process motion direction and speed.
-
- A: A higher refresh rate monitor, such as 144Hz or 240Hz, can display more fps than a standard 60Hz monitor, resulting in smoother and more responsive visuals.

- A: A higher refresh rate monitor, such as 144Hz or 240Hz, can display more fps than a standard 60Hz monitor, resulting in smoother and more responsive visuals.
-
- A: Lower fps rates can increase input lag, resulting in delayed responsiveness and decreased accuracy in games. A higher fps rate can decrease input lag and improve gaming performance.

- A: Lower fps rates can increase input lag, resulting in delayed responsiveness and decreased accuracy in games. A higher fps rate can decrease input lag and improve gaming performance.
-
- A: Higher fps rates can improve visual comfort and reduce eye strain for some people. However, individual sensitivity to flicker may vary, and in some cases, higher fps rates can actually increase eye strain.
