What is the critical fusion frequency?
Critical flicker fusion frequency (CFF or CFFF) is defined as the frequency at which flickering light can be perceived as continuous and it is used to assess the processing of temporal vision.
What is the CFF for humans?
The flicker fusion threshold, critical flicker frequency (CFF) or flicker fusion rate, is a concept in the psychophysics of vision. It is defined as the frequency at which an intermittent light stimulus appears to be completely steady to the average human observer.
What is animal CFF?
Critical flicker-fusion frequency (CFF) is “the threshold at which an animal ceases to perceive a flickering light source as a series of flashes, but rather as a continuous stream of light” (Inger et al. 2014: 2).
What is a critical flicker test?
Critical flicker frequency (CFF) is a test of retinal gliopathy (that occurs in patients with HE) that can be performed using a portable machine. 25. During this test, the patient is asked to indicate the maximum frequency at which they can still perceive the light as flickering while changing the frequency over time.
