Whilst there are no set adult screen times recommendations, they again are advised to spend no more than two hours before detrimental impact can occur. For children, it is recommended that under 5’s don’t exceed over an hour of screen time and a maximum of two hours for older children (Source: World Health Organisation). There are lots of high-quality research pieces about screen time exposure with recommendations for both children and adults. What can you do about blue light exposure?

Light is made up of several colours with blue emitting the highest energy of the spectrum due to its short wavelength. What is blue light and where is it found? But what do we need to pay attention to and what can we do about it?
