Humans have long been fascinated by the limits of their vision, and one of the most common questions asked is how many Hertz (Hz) can the human eye see? The answer is not as straightforward as it may seem.
The human eye is not capable of seeing anything beyond 60Hz. This means that monitors with refresh rates higher than 60Hz, such as 120Hz or 144Hz, are not actually seen by the eye. However, these higher refresh rates do offer advantages to the user.
The reason why higher refresh rates are beneficial is because of the way the brain perceives the image. When the eye transmits information to the brain, some of the characteristics of the signal are lost or altered in the process. This can lead to motion blur and other visual artifacts.
By increasing the refresh rate, the amount of information that is lost or altered is reduced. This results in a sharper, more detailed image that is easier for the brain to process. Higher refresh rates also reduce the amount of motion blur, making it easier to track fast-moving objects.
So while the human eye cannot see beyond 60Hz, higher refresh rates can still be beneficial. By reducing the amount of information lost or altered in the transmission from the eye to the brain, higher refresh rates can result in a sharper, more detailed image that is easier for the brain to process.
