Health and Vision
Light affects humans in at least two ways: it enables us to see and it
regulates our bodies' rhythms such as the sleep/wake cycle. Different
types and levels of light can affect a person's ability to see clearly,
identify people and objects, and drive safely. It can also
increase sleep efficiency of older adults and reduce symptoms
of seasonal affective disorder, or SAD, felt by many people
during winter months.
Light and Health program at the LRC strives to better understand how
the retina converts light signals into neural signals to the brain and
how lighting can be used to promote health and well-being of those
suffering from circadian disorders.
Every day, more people become interested in the potential benefits of light and dark, especially its effects on human health and wellbeing. Below are some highlights of LRC publications regarding light, health, vision, and overall wellbeing.
