Correcting Presbyopia with Autofocusing Liquid-Lens Eyeglasses
Most individuals older than 40 years old experience a progressive loss of vision accommodation. This results in significant degradation of visual acuity even when using state-of-the-art multifocal corrective eyeglasses. We present a new type of ergonomic, lightweight, opto-electromechanical autofocusing eyeglasses that adaptively change optical power to bring line-of-sight objects into focus. Subject-specific accommodation models were utilized to demonstrate high-fidelity accommodation restoration. This new type of active correction eyewear has the potential to restore pre-presbyopic levels of accommodation in subjects diagnosed with presbyopia... Read more
