Investing how blue light affects us
Blue light occurs naturally as part of sunlight and moonlight and, like all living things on Earth, we have evolved to respond to the daily cycle of light and dark.
There is growing concern that the increased exposure to artificial sources of blue light from lighting and digital screens is having an effect on our health, wildlife and the night sky. However, there are many things we can do to protect ourselves and te taiao the environment from artificial blue light.
CREST wants to shine a light on some of the concerns about artificial blue light and invites students to undertake a Blue Light CREST investigation.
