INNOVATIVE. ELECTRONIC. MOBILE. WEARABLE.
WEARABLE ADAPTIVE REFRACTOR
THE NEXT STEP IN THE
EVOLUTION OF SUBJECTIVE REFRACTION.
.
Subjective Refraction began a long time ago using trial frames with trial lenses. Manual and automated phoropters were then developed to speed up the process at the cost of less freedom for the patient and other disadvantages.
VisionFit brings subjective refraction back to the trial frames modality and well combines the advantages of both methodologies (speed of operation and maximum freedom for the patient).
VisionFit is an innovative electronic, tunable, all-in one, solid state, mobile and wearable system of lenses. It performs a subjective sight examination and it effectively replaces both the trial glasses and the manual/electronic phoropter functionality.
ELECTRONIC TRIAL FRAME.
Wearing the VisionFit electronic trial frame as a traditional trial frame, the subject looks at the eye chart or any other near or far target in any environment, either sitting or standing, thus allowing subjective refraction to be performed with the subject in his/her usual working environment and posture. Thanks to VisionFit lens technology, the subject can also move around with no operator intervention.

SIMPLE AND FLEXIBLE OPERATION.
VisionFit features a self-calibration procedure to ensure accuracy and reliability. It does not require any special installation procedure.
STEP 1
The patient wears the VisionFit lens frame like a regular trial frame and looks through it at an eye chart – or any other near or far target.
STEP 2
The patient can be sitting, standing or in any other desired position and/or environment.
STEP 3
The eye chart and/or target can be placed at different distances, depending on the type of exam.
STEP 4
The operator adjusts the device in order to change the position and configuration of the optics, asking the patient for a subjective feedback.
STEP 5
The operator selects the output values for both glasses and contact lenses prescriptions.
STEP 6
VisionFit provides versatile prescription printing options.
HOW IT WORKS
INNOVATIVE ADAPTIVE OPTICS.
The wearable trial frame contains an electronically tunable adaptive lens stack set
The adaptive lens consists of an adaptive spehrical lens (1), adaptive cylindrical lens (2), and an adaptive aberration lens (3)
The innovative aberration lens is a liquid lens consiting of four layers with 32 transparent actuators
