Sponsor's own description
Eye Care Professionals (ECPs) massively use auto-refractors during the patient journey to measure the objective refractive error: starting point of the subjective eye refraction. These devices provide objective information about the refractive and accommodative state of the eye, useful for the ECP to perform a complete eyesight test. Auto-refractor data for the distance vision are repeatable and accurate but near vision information are not enough reliable to build an accurate near vision routine exam. Previous internal studies, with auto refractors currently on the market, have shown that, during accommodation measurements, a large proportion of participants had a lower accommodative response than expected.
