experiments
  • 1 - Projection of an object on the retina

    experiment "Projection of an object on the retina"

    The image of an object is imaged upside down through the eye lens on the retina of the eye (frosted glass pane).


  • 2 - The function of the iris diaphragm

    experiment "The function of the iris diaphragm"

    The students learn about the function of the pupil.


  • 3 - The accommodation of the human eye

    experiment "The accommodation of the human eye"

    To see objects in focus closer than 5 m in front of the eye, the refraction of the eye lens must be increased by making it more curved.


  • 4 - The normal sighted eye

    experiment "The normal sighted eye"

    Students learn about the normally sighted eye.


  • 5 - Near-sightedness

    experiment "Near-sightedness"

    The students learn the myopic eye.


  • 6 - Far-sightedness

    experiment "Far-sightedness"

    The students learn the farsighted eye.


  • 7 - Demonstration of presbyopia (old people sightedness)

    experiment "Demonstration of presbyopia (old people sightedness)"

    The students learn about presbyopia.


  • 8 - The yellow spot and the blind spot of the eye

    experiment "The yellow spot and the blind spot of the eye "

    With the help of the image, the existence of the blind spot (no image perception at this point on the retina of the eye) can be experienced in the experiment.
