Abstract

The invention relates to an optical measuring device (1) for capturing at least one parameter of at least one eye (10l, 10r) of a test person (31) wearing the optical measuring device (1), comprising a frame (4), at least one frame insert (8l, 8r) attached to the frame (4) and at least one capturing unit (3l, 3r), wherein the frame (4) is designed to fix the optical measuring device (1) in such a way to the head of the test person (3l), that the at least one frame insert (8l, 8r) is positioned in front of at least one eye (10l, 10r) of the test person (31) for at least one direction of view of the at least one eye (10l, 10r) on the optical axis (K) of the at least one eye (10l, 10r), and the capturing unit (3l, 3r) is designed to optically capture the at least one parameter of the at least one eye (10l, 10r), wherein the capturing unit (3l, 3r) is arranged in such a way (a) that the optical path (M) for the capturing of the at least one parameter of the at least one eye (10l, 10r) excludes the frame insert (8l, 8r).

Claims

1. An optical measuring device for capturing at least one parameter of at least one eye of a test person wearing the optical measuring device, comprising a frame, at least one frame insert attached to the frame and at least one capturing unit, wherein the frame is designed to fix the optical measuring device in such a way to the head of the test person, that the at least one frame insert is positioned in front of at least one eye of the test person for at least one direction of view of the at least one eye on the optical axis of the at least one eye, and the capturing unit is designed to optically capture the at least one parameter of the at least one eye,

characterized in that,

the capturing unit is arranged in such a way (a) that the optical path for the capturing of the at least one parameter of the at least one eye excludes the frame insert.

2. The optical measuring device according to claim 1,

characterized in that

3. The optical measuring device according to claim 1,

characterized in that

the optical path entirely runs within a space which with the optical measuring device fixed to the head of the test person extends on the side of the frame insert facing the at least one eye.

4. The optical measuring device according to claim 1,

characterized in that

the at least one frame insert has at least one optical property.
