Flicker : a technological overview [PDF]
, 2022 Flicker can be annoying, but above all it can have a negative effect on human health; causing irritation, headaches, eye strain and migraines. With the introduction of LED lamps, flicker has once again become a problem.

Which lamp will be optimum to eye? Incandescent, fluorescent or LED etc
International Journal of Ophthalmology, 2014 Low frequency flicker, high frequency flicker, strong light, strong blue light, infrared, ultraviolet, electromagnetic radiation, ripple flicker and dimming flicker produced by different lamps have negative impact on vision, eyes and health.

Physiological Reports, 2020 Critical fusion frequency (CFF) reflects the basic temporal function of the visual system and therefore is a good measure of its performance. CFF has been implemented in psychological and pharmacological studies to evaluate cognitive functions.

Vision Research, 2017 Flickering lights can be uncomfortable to look at and can induce seizures in observers with photosensitive epilepsy. However, the temporal characteristics contributing to these effects are not fully known. In the spatial domain, one identified source of visual discomfort is when images have Fourier amplitude spectra that deviate from the natural (∼1 ...

Cone Electroretinography by Flicker [PDF]
Nature, 1951 IT is generally assumed that the b-wave of the human retinal action potential is due to the stimulation of the rods. With an intensity of 2,000 lux, the b-waves fuse at a frequency of about 20 flashes per second. At lower intensities the fusion frequency in our experiments decreased.

Quantifying the visibility of periodic flicker [PDF]
, 2017 Three experiments that measure the visibility of periodic flicker are presented. Temporal light modulations were presented to a large visual field to make the results valid for general lighting applications.
