Prof Gronfier is internationally recognised for his work on circadian biology and the impact of light on human physiology. In his talk, he discussed how light influences not only our circadian rhythms but also a range of non-circadian functions, shaping everything from alertness and cognition to long-term health outcomes.

The experts delve into the transformative potential of AI and quantum technology in the fields of healthcare and security. The discussion highlights the critical role of collaboration between academia and industry in driving innovation and addressing global challenges.

Key speakers include Xin Yan LIM from Moleac, a pharmaceutical company innovating in post-stroke recovery, and Raymond P. NAJJAR, a visual neuroscientist exploring the use of eye technology to detect brain diseases and mood disorders. They emphasize the importance of Singapore as a vibrant hub for research and industry partnerships, offering a conducive environment for technological advancements.

The conversation also touches on the need for integrated ecosystems where scientists, engineers, and industry players work together from the outset to ensure impactful outcomes. This video is a must-watch for anyone interested in the future of healthcare technology and the collaborative efforts needed to bring these innovations to life.

The session drew a keen audience of researchers and students, who actively engaged during the Q&A segment. His insights sparked discussions on how these findings could be applied in vision research, clinical practice, and even everyday life.

The World Sleep Congress is one of the largest international gatherings dedicated to advancing knowledge in sleep science, medicine, and technology. It brings together researchers, clinicians, and innovators from across the globe to exchange insights and showcase new discoveries in the field.

During the congress, Daniella had the opportunity to engage with experts in the field, receive valuable feedback on her work, and contribute to the growing conversation around light-based strategies for sleep and circadian health.

Dr. Raymond Najjar delivered a compelling talk on the impact of light exposure on myopia progression, shedding light on how environmental and optical factors shape visual development—a timely topic as myopia rates continue to rise worldwide.

Our team was also proud to showcase two impactful poster presentations. Dr. Murali presented his work on the synergistic effects of atropine and bright light in controlling lens-induced myopia in chickens, offering new insights into potential interventions for childhood myopia. PhD student Daniella Mahfoud presented her research on pupillometric features of ocular recovery following transsphenoidal surgery in patients with pituitary adenoma, highlighting the clinical value of pupillometry in tracking visual function and recovery.

During the session, Mr. Paolini highlighted how programmable spectrum sources offer multiple solutions for achieving the same correlated color temperature (CCT). He emphasized that daylight is the gold standard for lighting but also a complex and continuously changing spectrum. He explained that while daylight locus is sometimes representative of daylight, it does not fully capture its variability.

Mr. Paolini also pointed out that daylight CCTs are significantly higher than most electric lights, even during sunrise and sunset. He stressed the importance of deep red wavelengths (>650nm) for high CCT acceptance and accurate skin color representation. Lastly, he underscored the need to focus on radiometry, as photometry alone is insufficient for understanding daylight.Photo credits: Ms Janie Tay

Dr. Raymond P. Najjar was invited to deliver the keynote lecture at the Singapore Optometry Association Conference 2026, presenting a forward-looking talk titled “The Eye as a Gateway to Brain and Systemic Health: A Vision Beyond ‘Vision’.”

In his address, Dr. Najjar highlighted the expanding understanding of the eye as a critical interface between light, the brain, and whole-body health. He emphasised that light entering the eye has far-reaching effects—shaping mood, cognitive performance, sleep quality, and the synchronisation of the circadian system.
Dr. Najjar also underscored the growing role of the eye in disease detection. With advances in retinal imaging and artificial intelligence, the eye is rapidly becoming a powerful window into ocular, systemic, and neurological conditions, enabling earlier and more precise diagnosis.

Light has a profound influence on human health, cognition and well-being. Yet, across one’s lifespan, sub-optimal light exposure is leading to significant health decrements. The optimisation of exposure to light on a daily-basis, can lead to healthier eye and brain development. The LightSPAN Project, funded by the National Research Foundation of Singapore, was launched on November 9th, 2023. The project will investigate how we can optimize light exposure to support health and well-being across the lifespan.
