    Excellent.
    Set up to measure 1 minute of Arc resolution. Assumed to be "normal". Some normal eyes, can only read 1.5 minutes of Arc.
    The Snellen must have a bright light on it
    This is an excellent review.

    How do you express an angle in minutes and not in degree?

    • @optometry-with-samir
      @optometry-with-samir  2 года назад

      1 min arc is equal to 1/60 degree.
      For smaller angle min arc gives more accurate measurement. That's why we use min arc instead of degree.

    Why only black letters on white board
    But not colored letters

    • @optometry-with-samir
      @optometry-with-samir  Год назад

      Because we measure only "form sense" of vision with visual acuity chart.
