<p>The present invention pertains to the field of medical techniques and more precisely relates to refractometers used for determining vision parameters. The refractometer of the present invention increases the precision of eye-parameter definition while presenting a simplified structure. This device can further be used for training the eye muscles using corresponding medical methodologies. In a first embodiment, the refractometer comprises an optical focusing member (1), a test object (2), an optical axis (3) and a measuring element (4). The optical focusing member is optically related to the test object which, in the case of a normal vision, lies in the focal plane of said optical focusing member. The optical focusing member and the test object are further arranged so as to be capable of mutual displacement along the optical axis.</p> |
