How Many Fps Can The Human Eye See

How Many Fps Can The Human Eye See? Explained and Debunked!

The human eye is a marvel of nature, capable of processing and interpreting millions of bits of information per second. Even though we take our eyes for granted, they are incredibly complex, and we still do not fully understand how they work.

One of the most popular questions about the human eye is how many frames per second (fps) we can perceive. The simple answer is that the human eye can perceive up to 1000 fps, although that’s just half of the story.

To understand the complex relationship between the human eye and fps, let’s study how the eye works and the factors that impact our perception of fps.

How the Human Eye Works

The human eye is a natural camera that works in a similar way to a camera’s shutter. The outermost layer of the eye, the cornea, refractors the light that enters the eye, directing it towards the lens inside the eye.

The lens, which can change shape and curvature, focuses the light onto the retina, the innermost layer of the eye. The retina contains millions of photoreceptor cells called rods and cones that convert the light into signals that are transmitted to the brain via the optic nerve.

The brain then processes these signals, creating the images that we see. However, this processing takes time, and our perception of motion is based on how quickly the brain can interpret these signals.

Factors that Affect Perception of FPS

Although our eyes can detect up to 1000 fps, we do not necessarily see all of them. Many factors impact our perception of fps, including:

1. Age: As we age, our eyesight deteriorates, and our perception of fps reduces.

2. Distance: The closer we are to an object, the more details we can see. However, this means that we can detect fewer fps compared to observing an object from afar.

3. Contrast: The contrast between the object and the background affects our perception of fps. If the object is in sharp contrast with the background, we can perceive more fps.

4. Lighting: The lighting conditions affect our perception of fps. We can perceive fewer fps in low light conditions and more in bright lighting.

Myth: The Human Eye Can See 60 fps

One of the prevalent myths about the human eye and fps is that we can only perceive up to 60 fps. This myth is often perpetuated by people who claim that higher fps in video games do not make a difference as the human eye can’t see the difference.

However, the reality is that the human eye can perceive much higher fps than 60 fps. As discussed earlier, we can perceive up to 1000 fps, although factors like age, distance, lighting, and contrast can impact our perception.

The Future of High-FPS Displays

While current technology limits the fps that we can perceive, advancements in display technologies may soon enable much higher fps. For example, a 120Hz refresh rate on a display can produce smoother motion than a 60Hz refresh rate, although the difference is not noticeable to everyone.

However, with the rise of virtual reality and augmented reality technologies, high fps displays may become more critical as these technologies require ultra-smooth motion to create a believable experience.


The question of how many fps the human eye can see is a complex one, with several variables impacting our perception of fps. Although we can detect up to 1000 fps, we may not necessarily see all of them due to factors like age, distance, contrast, and lighting.

The myth that the human eye can only perceive 60 fps is just that, a myth that has been debunked by scientific research. As display technologies continue to evolve, higher fps displays may become more common, especially in virtual reality and augmented reality applications.
