Optimising Light across LightSPAN



Light exposure is key to our health and well-being. Many research studies have found that light at the right time can support our biological clock and our sleep. In ageing, bright light can ameliorate cognitive decline. More recently, exposure to bright light in children has been linked to delaying myopia onset.

The LightSPAN Project, funded by the National Research Foundation of Singapore, will investigate how we can optimize light exposure to support health and well-being across the lifespan.

LightSPAN is led by Prof. Dr. Manuel Spitschan (TUMCREATE & Technical University of Munich) and Asst. Prof. Raymond Najjar (National University of Singapore).

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.


We invite you participants to register their interest and join us in understanding the pivotal role light plays in boosting eye and brain development and how light can be leveraged and optimised to boost resilient ageing through our novel light exposure app, LightUP.
