Researchers at the University of Alabama at Birmingham (UAB) School of Optometry have received a patent for a novel lens design intended to slow or halt the progression of myopia in children, according to a university press release. The patented technology was developed by Tim Gawne, PhD, professor, and Thomas Norton, PhD, professor emeritus, following decades of research into the mechanisms that regulate eye growth.

The lens design modifies the chromatic structure of light reaching the eye and is based on research into emmetropization, which can lead to excessive axial elongation and myopia if it fails during child and young adult development. The new lens is designed to alter those visual cues to reduce or prevent abnormal eye growth, myopia, and even sight-threatening diseases later in life, Dr. Gawne noted in the press release.

Drs. Gawne and Norton’s work builds on long-term investigations into how the visual system interprets focus signals. Dr. Norton has studied the mechanisms underlying myopia development for nearly 50 years and has collaborated with Dr. Gawne for more than a decade.

The press release describes the patent as a step toward translating basic vision science into clinical application, which adds to ongoing efforts to develop further optical interventions for myopia control. Patent protection is expected to support further development of the technology by enabling investment and facilitating clinical trials. According to the researchers, securing intellectual property is a key factor in advancing innovations from laboratory research to real-world use.

The patent was issued with support from the Bill L. Harbert Institute for Innovation and Entrepreneurship, which manages UAB’s technology transfer activities, including patenting and licensing.

Dr. Gawne currently has additional patents in development related to similar approaches.OM
