The eye plays an important role in our life, not only for seeing objects in the surrounding world, but also for reading letters, viewing paintings, photographs, films, etc. The visual acuity of the eye is generally regarded as the most important factor for the ability of the eye for seeing objects. The acuity of the eye is usually measured by acuity tests where single black letters on a white background have to be recognized, or where the minimum visible separation is measured of black rings with a small interrupted part (Landolt rings). These tests are used for decisions about the use of certain types of eye glasses, but give no information about several other factors that also play a role in the properties of the human visual system.
