The development and adoption of smart contact lenses are intrinsically linked to advancements in Material Science, specifically the properties of Hydrogel, Silicone Hydrogel, and Scleral materials. For a lens to be "smart," it must first be a superior contact lens, meaning it must be flexible, comfortable, and, most importantly, highly permeable to oxygen, ensuring corneal health during continuous wear.

Silicone Hydrogel has emerged as the preferred material for smart lens prototypes. While traditional Hydrogel is known for its high-water content and comfort, Silicone Hydrogel offers a vastly superior oxygen permeability (Dk/t), which is crucial when electronic components are embedded, as they can potentially reduce the overall oxygen flow to the cornea. The inherent flexibility and durability of Silicone Hydrogel make it ideal for integrating microscopic sensors, circuits, and batteries.

The material segment also covers Scleral Lenses, which are larger lenses that rest on the white part of the eye (sclera) rather than the cornea. These lenses offer a larger surface area, providing more space to embed electronics, and are often used in medical applications or for patients with complex vision needs, offering a unique opportunity for high-capacity smart lens designs.

Material development is critical for achieving regulatory approval, which requires stringent testing for safety and long-term corneal health. Companies like Alcon and Bausch and Lomb bring their extensive experience in traditional lens manufacturing to the smart market, focusing on optimizing the comfort and biocompatibility of the final product. The material segment's evolution ensures that the market can successfully scale its innovative functionalities.
