Electronic wearable devices have gained significant traction and popularity in recent years. Wearable devices are designed to possess data processing for health and fitness [1–3]; biometric tracking, temperature regulation, and posture correction such as smart clothing; immersive experiences of the human-machine interface through Augmented Reality (AR) and Virtual Reality (VR); personal safety and security of emergency assistance or location tracking; and medical and assistive devices such as wearable Electrocardiogram (ECG) monitors, smart prosthetics, and smart contact lens. The emergence of smart contact lenses represents a remarkable advancement in wearable technology, offering numerous potential benefits and transforming the way we interact with the world. These innovative devices, worn directly on the eye, integrate cutting-edge electronics, sensors, and wireless communication capabilities to provide a range of functionalities beyond traditional vision correction. In the future, smart contact lenses are expected to revolutionize various aspects of our lives. They hold immense potential in the fields of healthcare, augmented reality, and personalized computing. One of the key drivers for their development is the need for non-intrusive, unobtrusive health monitoring. Smart contact lenses have the potential to continuously and non-invasively monitor vital signs and biomarkers, enabling early detection of diseases and providing real-time health insights.
