Direct linkSilveira, M. V.; Barthem, R. B.; Santos, A. C. F. – Physics Education, 2020
This work presents an experiment that seeks to simulate human color vision through electronic components in an attempt to build, together with the students, a cybernetic 'eye'. The limitation of the cybernetic eye developed here in relation to the standard human chromatic vision, which makes it a 'colorblind eye', is an argument to be explored by…

Cortel, Adolf – Physics Education, 2005
Many simple experiments can be performed in the classroom to explore the physics of vision. Students can learn of the two types of receptive cells (rods and cones), their distribution on the retina and the existence of the blind spot.

Peer reviewedMastebroek, H. A. K.; Van Der Kooi, J. B. – Physics Education, 1979
Discusses human ability to perceive repeated sensory stimuli in the visual system, and explains that its frequency fc has a critical value, under normal conditions, about 40 Hz. (GA)
