Abstract
A trial frame includes a trial frame body and at least one measurement subject having a visual invariant geometric characteristic. The trial frame body has at least one key parameter. The measurement subject is disposed on the trial frame body and collaborates with a measurement method. A two-dimensional image of the measurement subject is recorded by an image capturing device when the trial frame body fits to a user, and the key parameter is deduced from the two-dimensional image of the measurement subject.
