a variety of test symbols are used by ophthalmologists and opticians. In addition to Landolt rings, Snellen charts, letters and numbers, symbols can also be used which are displayed at a specified distance [...] light must be focused on the retina. The better this process works, the sharper our vision - and we are then able to distinguish objects from each other with greater precision. Visual acuity is the sharpness [...] the retina. Reduced visual acuity Visual acuity is influenced by a wide variety of factors, which are determined not only by the eye itself but also environmental influences. The interaction of the eye
