Lens Types

Freeform is a digital manufacturing process that uses computer-aided design and surfacing to create high-level, customised optical lenses with your unique prescription and frame choice.

The result is sharper vision through increased contrast perception, exceptional low light vision with glare reduction, maximised optics to provide brighter and more intense colours.

IOAC Optical uses freeform technology in our single vision, enhanced readers and multifocal lens designs.

Digital Ray-Path Lens Technology

Digital Ray-Path is state-of-the-art technology based on an accurate simulation of the eye in its full complexity. This technology creates completely personalised lenses optimised for a single wearer. Even two wearers with the same prescription and lens material will receive different lenses comprehensively tailored to their individual biometrics and frame selection.

The result is better vision through every point of the lens, wider visual fields for superior comfort and individual lenses tailored specifically for you.
