In this edition, we will explore the recent developments in eye tracking technology, discussing both the clinical and commercial applications of the technique. First, we investigate the future of contact lens material technology and listen in to a debate between leading experts in the contact lens field.

    In the last two decades, there have been great advances in vision testing and screening software. With cutting edge technology becoming more accessible, new techniques are being developed to examine ocular movements. A new clinical eye tracker provides a powerful tool for diagnosing and managing a wide range of conditions including binocular vision anomalies, various neurological conditions and reading difficulties. The device uses infra-red cameras to detect eye position to an accuracy of as little as one degree and records exactly where the patient is looking. David Thomson, former Professor of Optometry at City University, speaks to Polly Dulley about this latest innovation in eye assessment.
