What Frequency Can the Human Eye Perceive?

Discover the frequency limits of human vision and how light is interpreted by our eyes.

The human eye cannot see in Hz because it detects light in terms of wavelength (nanometers) rather than frequency (Hertz). However, flicker fusion threshold, the frequency at which flickering light is perceived as steady, varies typically between 60 to 90 Hz for most individuals.

FAQs & Answers

  1. What is the flicker fusion threshold? The flicker fusion threshold is the frequency at which a flickering light source is perceived as steady, typically ranging from 60 to 90 Hz.
  2. Can humans see in Hertz? Humans cannot see in Hertz as our eyes detect light in terms of wavelength measured in nanometers.
  3. What wavelengths can humans see? Humans can typically see light in the wavelength range of 400 to 700 nanometers.
  4. How does light frequency affect vision? Light frequency affects how we perceive motion and flickering; higher frequencies can enhance the perception of steady light.
