The Spanish National Research Council (CSIC) Spin Off has developed SimVis, a medical device that allows patients to experience the real world through multifocal corrections before any surgical or contact lens fitting procedure. This see-through device simulates a patient's vision, enabling opticians to recommend personalized assessments before treatment. 2Eyes Vision leverages technology to offer a noninvasive and innovative solution to presbyopia, a condition that affects 100% of the population above 45 years old.
