Clinically designed to slow myopic progression while preserving central vision clarity.
Myopia is rising rapidly and could affect over half of the global population by 2050. Casiolens YOULI lenses aim to slow this trend by targeting the optical causes of eye elongation—not just the symptoms.
Peripheral hyperopic defocus is a known signal for axial eye growth. YOULI lenses redirect this signal by introducing myopic defocus zones across the lens surface to inhibit elongation.
At the heart of YOULI is a grid of 1,339 microlenses that subtly alter peripheral light rays while preserving sharp central vision—delivering both correction and control.
All lenses use durable, high-index polycarbonate and integrate UV and blue light filters directly into the material.
