The majority of diagnostic instruments in eye-care are currently stationary, expensive, invasive, complicated to use and rather time consuming.
To be effective, the screening device must be easy to use, be fast, non-invasive and very cost effective. The 2WIN is a mobile binocular Refractometer and vision analyzer that measures both eyes at the same time, in real life vision conditions.

| Applications & Benefits of the 2WIN
VisionFit in combination with 2WIN binocular handheld refractometer and vision analyzer, the operator performs an objective and subjective refraction exam in only a few minutes, with maximum mobility and flexibility.
▪ Quick and non-invansive measurement of binocular manisfest refraction
▪ Accurate objetive measurement of ocular deviations, both tropas and phorias
▪ Detection of the major amblyogenic factors such as anisometropia, anisocoria, media opacities, etc
▪ Over-refraction with both spectacles and contact lenses
▪ Objective measurement of dynamic pupilometry

▪ Objective analysis of under- or over-corrections
▪ Objective orthoptic exam
Features of the 2WIN
| Eccentric Photo-Retinoscopy
The 2WIN measurement principle is eccentric photo-retinoscopy. Infrared (IR) light is projected through the patient pupils and onto the retina. Depending upon the refractive error, the reflected light forms a specific crescent-shaped brightness pattern within the pupil.
The 2WIN measures spherical power, cylinder power and axis by interpreting the reflected light crescent pattern and position. The 2WIN infrared exam also provides valuable information about corneal abnormalities as well as ocular media opacities such as cataracts.
| Binocular / Monocular Refraction
The 2WIN takes the measures in natural mydriasis and factors in accommodations which influences the measurement of hyperopic refractive errors. Such influence can be reduced by a dim light environment and no strong accommodation stimuli (i.e., no luminous fixation targets). In addition to that, the 2WIN features an age-related software compensation techniques referred to accommodation.
The 2WIN measurements are closer to the final prescription on patients with a strong accommodative response.
EXTENDED MEASUREMENT RANGE
The 2WIN covers an impressive measurement range of spherical power from -15D to +15D.
Phorias and Tropias Early Detection
The 2WIN is capable of diagnosing Myopia, hyperopia, astigmatism and other factors. Additionally, it will provide evidence of sight anomalies that may be related to anisometropia, anisocoria, strabismus, phorias.
| Gaze Measurement
The Package will add the feature to collect data from 3 measurements and analyze the corneal reflex. Results are expressed either in prism diopters or in degree.
| Pupil Size Measurement
The 2WIN provides accurate and instant pupila size, pupila distance and head tilt.
| Refracts Over Lenses
The 2WIN preforms over-refraction very easily and effectively with both spectacles and contacts. It checks the optical corrections making the results objective, stored and documented.
| Non-invansive, fully automated and easy to use
The 2WIN works as a camera and operates at three feet (1 meter) distance; it needs only 3 seconds to get a complete screening of the patient, immediately providing a detailed PDF report to print and share.
| Can refract patients as young as 2 months old and up to 120 years old
The 2WIN is designed to perform refractions on patients of all ages.
| Kids Mask Kit
The 2WINNY mask is fun and attractive. It is removable to help the operator select the mask appropriated for the child. . It is an accessory designed to draw the child’s attention to the 2WIN during the examination while activating the visible and audible fixation targets. The operator selects the mask on the basis of child’s age. The mask can be attached to the front of the 2WIN.
| LC-App | Lens Centering on Frame
Correspondence between the optic center of the lens and the actual visual axis of the eye (corneal reflex) for better visual comfort.
| CR-App | Measurement of Tropias and Phorias
The CR-App compares the position of the corneal reflexes in three different measurements (the first binocular, the second and the third monocular under an infrared occluder).
| DP-App | Dynamic Pupillometry
Automatic measurement of dynamic pupils response under programmable light stimulations. This function removes subjectivity from the pupillary evaluation and helps the detection of pupillary behavior.
|| 66cm-App | Intermediate Distance
The 2WIN measures the patient’s refraction while reading from VDU’s (i.e. computer monitor), at a distance of 66 cm (2’). When reading at such a distance proves difficult, the 2WIN calculates the necessary addition power to restore best vision. The application requires the use of an additional lens, inserted in the central aperture of the 2WIN, and an eye-chart applied on the instrument.
