IOT Debuts Light-Form Technology

IOT unveiled Light-Form Technology, its digital additive manufacturing technology for ophthalmic lenses, last month at MAFO–The Conference 2026, a global industry event for the international eyewear community. At the event, Light-Form Technology earned the Best Presentation award during its public debut.

Light-Form Technology represents a shift in prescription lens manufacturing by departing from traditional free-form surfacing methods. By utilizing a controlled volumetric photopolymerization process, the prescription lenses is built in one step using a single flash of light.

Company Reaction

IOT says this new ophthalmic lens manufacturing process results in precision, speed, cleanliness, and sustainability, simplifying production while also reducing the environmental footprint. “Light-Form enables the creation of fully customized prescription lenses in seconds—without water consumption, without plastic waste, and with up to 90% less energy use,” says Daniel Crespo, IOT’s CEO.

According to Chief Innovation Officer Jose Alonso, the key to Light-Form Technology is stabilizing a phenomenon known as frontal photopolymerization. “The beauty of Light-Form is that we build the entire lens volume in one go—no layers, no stair-stepping, no post-polishing.”

Potential Applications

IOT cited several opportunities for this lens manufacturing innovation, including

• Decentralized, last-mile manufacturing. This enables opticians and micro-hubs to deliver same-day lenses.
• Deployment in remote or low-resource regions. This extends access to vision care.
• Next-generation optical applications. Potential applications include augmented reality optics and future smart-glass components.
