Determining objective measurement data during a subjective refraction

A method for determining objective measurement data of at least one eye of a user during a subjective refraction, the method comprising:

• a) acquiring subjective refraction data of the at least one eye in a first lighting state;
• b) acquiring and/or ascertaining pupillometric measurement data of the at least one eye in the first and a second lighting state different from the first lighting state;
• and
• c) acquiring aberrometric measurement data of the at least one eye in the first and second lighting states;
• or
• d) acquiring aberrometric measurement data of the at least one eye in the first or the second lighting state and ascertaining aberrometric measurement data of the at least one eye in the other one of the first and second lighting states taking into account the acquired and/or ascertained pupillometric measurement data of the at least one eye.

A measuring device for determining objective measurement data of at least one eye of a user during a subjective refraction, comprising:

• a refraction unit configured to acquire subjective refraction data of the at least one eye in a first lighting state;
• a pupil measuring unit configure to acquire and/or ascertain pupillometric measurement data of the at least one eye in the first and a second lighting state different from the first lighting state;
• an aberrometry measuring unit configured to acquire aberrometric measurement data of the at least one eye in at least one of the first and second lighting states;
• and
• an aberrometry ascertaining unit configured to ascertain aberrometric measurement data of the at least one eye in the other of the first and second lighting states taking into account the acquired and/or ascertained pupillometric measurement data of the at least one eye.
