The ergonomic refraction station and procedure of use consists of a phoropter helmet, chair, work table, monitor and electronic circuit, which seeks to perform a refraction test in the conditions most similar to the usual work environment of the examinee, for this it consists of a lightweight phoropter helmet, which adjusts to the size of the user, made of transparent material to allow contact with its surroundings and execute the usual movements of head, neck, eyes and working distance, parameters that are captured by optical, distance and inclination sensors, located on the phoropter helmet or on the flexible and adjustable table with "swan neck" arms, so that once the patient places the phoropter helmet and sits on the chair and table, the sensors send information to a microprocessor that shall recognize the real working conditions of the patient and adapt them to the conditions of the ergonomic refraction station, such as: size of letters, aligned inclinations of head-eye-hand coordination with the vision charts, lighting and thus adequately projecting the reading chart on the table and the characters and graphics that the examinee shall read； It also includes removable multifocal lenses or in a test case with the appropriate coupling, noncircular eyepieces with a greater visual field than the traditional ones for the far, middle and near vision test and ocular covers.
