MEDICAL DAILY: Light-Activated Compounds Designed to Stand In for Lost Photoreceptors Restore Visual Behavior in Blind Animals 28.8.2026 | Institute for Bioengineering of Catalonia A research consortium led by the Institute for Bioengineering of Catalonia in Barcelona has developed a family of light-switchable small molecules designed to occupy the gap. The compounds, called prosthe6, restored visual responses in zebrafish and mouse models of retinal degeneration under ordinary ambient light. https://ibecbarcelona.eu/es/medical-daily-light-activated-compounds-designed-to-stand-in-for-lost-photoreceptors-restore-visual-behavior-in-blind-animals
