HOYA visuSense features two interactive measurements which lead to the Visual Sensory Intelligence of the patient. HOYA GazeTrack captures the patient’s visual pattern, posture and head movements when switching gaze between near and far distances. HOYA ClarityTrack assesses the patient’s visual preferences in terms of clarity requirements and blur tolerance as well as their details perception, during reading or other close-up activities. visuSense offers a powerful way for Eye Care Professionals to differentiate their practice. By integrating each patient’s distinct visual sensory profile, state-of-the-art solutions are delivered, tailored to the needs of even most discerning presbyopic patients.
