Any damage caused to the eye by blue light happens gradually, so it’s vital to act now to prevent any major health issues, before it’s too late. 

A quick solution is by simply understanding the different effects light can have on us during the morning and evening and adapting the lighting in our environments accordingly, thereby using our surroundings to guide our body clocks.

For example, we can do this by employing softer lighting from the red end of the colour spectrum in the evening when it is time to relax, and brighter lights containing higher energy wavelengths from the blue end of the spectrum in the daytime. The red light at night will help shift circadian rhythm and suppress melatonin, while the blue light will encourage our brains to be more alert and focused.

We should also be aware that most of us are exposed to blue light via the screens of modern technology at night time. This can cause detriment to our body clocks, and provide our brains with misleading information.

Therefore, prevention is as simple as limiting the amount of blue light passing through our eyes, and making sure we are exposed to light at the right times during the day.
