Parallelism of visual axes, the normal eye muscle balance. Packages Additional software features that can be installed directly on 2WIN. Refraction When referred to human eye, this term, or the term Refractometry, are used to indicate the measurement of the Refractive Error, that is the error in the focusing of light by the eye.
4. Intended use of the device Instrument for the measurement of binocular and monocular refraction, via dynamic photoskiascopy. 5. Classification and Applied Standards Classification according MDD 93/42/EEC, Annex IX Class IIa Classification and type of applied parts There are no applied parts. IP classification IPX0 (degree of protection provided by the external plastic shells with reference to the penetration of any special material or water).
helpful hints related to your product. Important The 2WIN is a binocular refractometer and vision analyzer. It measures refraction of both eyes at the same time, at a distance of 1 meter. The 2WIN should not be confused with a table-top auto-refractometer (AR). ARs are designed to measure refractive errors of one eye at time, in an artificial condition of far fixation.
A stable measurement distance of 1 meter is also important. Exam procedure (Quick mode – default) Turn the 2WIN ON by pressing the ON/OFF button for 1 sec. and wait until the stand- by screen appears. Instruct the patient to keep his/her eyes wide open, clear of eyelids or eyelashes, and to fixate the centre of the camera (possibility to activate a small central LED in the 2WIN Menu).

Screen examination – blurred, not in focus. Adjust the distance from the patient Adjust the distance to focus the image until the top bar is green (for details on screen tips also see: Verify the position of the subject / Check the position of the subject). ...
2WIN displays “high M” (myopia) or “high H” (hyperopia). In the case the 2WIN displays “high M” or “high H” without displaying a numerical result (N.A., not accessed measurement), we suggest using a 10 D trial lens to offset refraction within the measurement range.
It can be connected to a mini-printer, via IrDA (Infrared Data Association) interface, to print the measurement results onto a strip of paper. 2WIN can be accessorized with a Wifi transmitter module. A label inside the USB & SD connection door identifies the presence of the Wifi module.

Insert battery To insert the battery: slide the battery lock, hold it and gently open the battery door located in the lower side of the device. Insert the battery. Pay attention in inserting the battery with its connector facing down towards the instrument's inside so that the connector of the battery matches the connector inside the device.
When the device is connected to a computer via USB port the turning off is prevented. When you try to switch off the 2WIN a warning will advise you to remove usb cable. Before operation After charging the battery, be sure to set up date and time.
While the instrument is on, the monitor reduces the brightness after 30 seconds of inactivity. Then the monitor switches off after 30 seconds more. The 2WIN goes in standby after 1 min if normal or 10 min if Wifi is activated). After 600 seconds of standby mode, the device turns on, emits a sound alert, and shows a warning telling that after 30 seconds it will automatically shutdown.
Environment setup For a proper use of the device it is important to prepare the environment for the examination. Verify adequate light conditions The ambient light should be low, there should be no lamps directly pointed towards the instrument and every direct source of light should not be seen by the device or reflected by eyes of the patient.
Page 29
Verify the position of the subject: The subject to be tested has to be 1 meter ± 5 centimeters (3 feet and 3 inches ± 2 inches) away from the device. In case of an incorrect position the feedback from the machine will help to evaluate the position.
Instrument setup As soon as powered ON, the device will perform a fast auto-test, then it will turn directly to exam mode, and the display will show the screen depicted below. As the device features different kinds of measurements, and different exam modalities, an instrument setup must be performed before performing an examination or a sequence of examinations.
Power-ON screen with OS Please notice that the there is an inversion of left and right due to the fact that the patient and the machine are one in front to the other. Therefore the sign OS will appear on the right half of the screen, and viceversa.

Preparation of the patient During the exam the patient must look at the device, staring to the central front hole of the device. The operator shall instruct the patient to look at the device and to try to open wide his eyes so to avoid eyelashes covering the pupils.
Measurement tips: usually the RED condition depends on a bad distance between the 2WIN and the patient. When the top bar is RED adjust the distance between the 2WIN and the patient in order to focus the image and to obtain a GREEN top bar.
Page 36
5. When the top bar is PERMANENTLY green release the BUTTON S1/S2 - the message "MEASURING" " will appear. Examination screen – focus OK 6. Stay firmly in the condition in which the upper bar is green until the message DATA PROCESSING appears on the display.
Page 37
This label indicates if the eye presents a diopters value higher that 5 D of spherical equivalent. If n.a. is displayed when High M/H appears, this indicates that the refraction is outside the range of the 2WIN measurements range.
Page 38
'Normal Mode' can be activated from Menu > Measurement > Measurement Modes > Normal Mode. This modality of examination and image acquisition has been the 2WIN default up to version 3.0 while after this version the Quick Mode is the suggested and default mode.
2. Center the eye/s of the patient in the display live area, inside the blue rectangle (measurement area) – the message “FOCUSING” will appear. 3. Adjust the distance to the patient in order to focus the image (for details on screen hints see also: Verify the position of the subject) so to maximize the length of the colored bar: the longer the bar, the best the focus.
