2WIN-SFirst and Unique Binocular Stand-alone Vision Screener
The most reliable device to detect refractive errors and vision abnormalities
2WIN-S is a binocular and portable vision screener that measures the refraction of both eyes and discovers other ocular impairments. The Kaleidos tube serves as a darkroom for the device and allows the exam to be performed in any light condition: while the patient looks inside of it, the system automatically detects refractive errors in less than three seconds. 2WIN-S measures objective refraction in the range of -15D to +15D, and phorias/tropias in prismatic diopters, as well as other additional features.
Complete, clear and sharable exam report
2WIN-S communicates with a tablet through an intuitive app, which can also be used to store and share data with collaborators, colleagues or patients.
Binocular refraction measurement in natural light conditions.
Refractive errors: myopia, hyperopia, astigmatism and other amblyogenic factors.
Early detection and documentation of multiple amblyogenic factors.
Capable of un-aided binocular refractions.
Detects visual anomalies related to anisometropia, anisocoria, strabismus, and phorias.
Pupil parameters: pupil size, pupil distance and head tilt.
Able to obtain a refraction with different pupil size.
Measurement of dynamic pupils response to programmable light stimulations.
Easy to use
Due to its automated functions, it is easy to use.
Fast and accurate
Extremely fast, accurate and consistent measurements.
Perfect in any light conditions
Entirely independent of environmental light conditions.
Allows you to delegate measurement to your collaborators.
WiFi printer supported
Enables the operator to share, record, check remotely or print exams.
App based system
Operates using an application on an Android tablet or smartphone.
The perfect start to define the eyes’ necessary correction.

All the information you need to use our device at its best.
2WIN-S allows simultaneous evaluation of refraction and binocular cooperation of subjects in natural (without cycloplegia) and not dissociating conditions, as opposite to autorefractometers, which only work monocularly.
