The Science Behind High Refresh Rates
A refresh rate is the number of times a monitor updates the image on the screen per second. A higher refresh rate means a smoother, more responsive visual experience. Traditional monitors typically have a refresh rate of 60Hz, while high-end gaming monitors can have refresh rates of 144Hz, 240Hz, or even higher.
So, how does a higher refresh rate reduce eye strain? The answer lies in the way our brains process visual information. When a monitor updates the image at a high refresh rate, it reduces the amount of motion blur and screen tearing, creating a more stable and comfortable visual experience.
Motion Blur and Eye Strain
Motion blur occurs when the eyes have trouble tracking fast-moving objects on the screen. This can cause eye fatigue, as the brain struggles to process the visual information. A higher refresh rate reduces motion blur, making it easier for the eyes to track moving objects.
Screen Tearing and Eye Strain
Screen tearing occurs when the monitor displays multiple frames at once, creating a “tear” in the image. This can cause eye discomfort, as the brain struggles to process the conflicting visual information. A higher refresh rate reduces screen tearing, creating a more stable and comfortable visual experience.
