Watch the trailer

This documentary follows Professor John Nolan’s 20-year exploration of one of modern science’s most overlooked frontiers: the powerful link between nutrition, vision, and brain health. Directed and produced by two-time Emmy Award winner Wayne Chesler, it reveals how solutions to some of our greatest health challenges may lie not in distant breakthroughs, but within our own biology.

From the marigold fields of Mexico to research labs in Ireland, the Norwegian seas, and elite performance centres in Singapore, the film uncovers the science behind nutrients that support how we see, think, and age. As conditions like macular degeneration and dementia become increasingly common, it offers a hopeful message: by understanding nutrition, we can shift from reacting to decline to actively protecting our future health.

Ageing may be inevitable but how we age is something we can influence.

Professor John Nolan

Professor John Nolan

Scientist | Innovator | Educator
Fulbright Scholar and founder of the Nutrition Research Centre Ireland, translates pioneering research on targeted nutrition for vision and brain health into practical solutions for healthier ageing.
Read full bio
Professor John Nolan is a Fulbright Scholar, full Professor at South East Technological University (SETU), and holder of the Howard Chair in Human Nutrition. He is Founder and Director of the Nutrition Research Centre Ireland (NRCI), an internationally recognised research centre dedicated to understanding how targeted nutrition supports vision, brain health, and healthy ageing (all explained when you watch “A Vision for Vision”, we hope!) For more than two decades, Professor Nolan has led pioneering work demonstrating that specific nutrients, particularly the eye (macular) carotenoids lutein, zeaxanthin, and meso-zeaxanthin play a critical role in visual performance, cognitive function, and protection against age-related diseases. In 2011, he was awarded a prestigious European Research Council (ERC) grant to lead the landmark Central Retinal Enrichment Supplementation Trials (CREST), large-scale human studies that showed nutritional intervention can measurably enhance visual function in both the general population and patients with age-related macular degeneration (AMD). These findings helped redefine how clinicians think about prevention and performance in eye care. More recently, his team’s research has expanded into brain health and dementia, providing evidence that the same nutrients (with a little help from the omega-3 fatty acids, ok; again watch the film) that protect the eye also support memory, cognition, and quality of life in ageing adults and individuals living with Alzheimer’s disease. Professor Nolan has authored more than 120 peer-reviewed scientific publications and is widely regarded as a global leader in nutrition and vision science. He is also the founder and Chair of the international Brain and Ocular Nutrition (BON) Conference, a platform that brings together the world’s leading researchers and clinicians to advance evidence-based practice. Through his science, teaching, entrepreneurship, and public engagement, including A Vision For Vision Professor Nolan’s mission is simple: translate rigorous research into practical solutions that help people see better, think clearer, and live longer, healthier lives. He calls this Health 3.0.
