Traditional semiconductor processing, which requires rigid, flat surfaces, was always incompatible with the flexible design of contact lenses—until now. Purdue researchers have cracked the code by using semiconducting nanomaterials along with metallic and insulating traces. These advancements allow the lenses to function as thermal actuators, wireless power supplies, and an array of sensors, all while maintaining their natural appearance.

The possibilities for this innovation are transformative. The team has already demonstrated how the lenses can treat dry eye syndrome by applying controlled heat to unclog meibomian glands, the primary cause of the condition. This noninvasive approach combines cutting-edge technology with patient comfort, offering a glimpse into the future of personalized eye care.

But the potential doesn’t stop there. The smart contact lenses open doors to a range of applications. Beyond medical treatments, they could serve as a platform for delivering ocular medication or even enhance augmented reality experiences. By combining the familiar design of a contact lens with groundbreaking technology, this invention could reshape how we interact with the world.

This innovation is protected under multiple patents, including U.S. Patent No. 12,145,336 issued in November 2024. It represents years of research and development, underscoring Purdue’s leadership in biomedical engineering and health technology.

Professor Lee’s work is more than a technological achievement. It’s a testament to the power of innovation to solve real-world problems. By rethinking what a contact lens can be, his team is redefining the boundaries of science and medicine.
