Abstract:
The circumstances which can influence the determination of the static central visual acuity are enumerated. The TNO Landolt C chart can be improved. A modified Landolt C letter chart is introduced on which the optotype is presented in 8 different positions, in vertical rows of ten per visual step above visual acuity 0.3.
