The Hazard of Blue Light

In the past few years there has been increasing worry among vision scientists and eye care providers over the “Blue Light Hazard” –  High Energy Visible (HEV) Light which can be emitted by flourescent lights and the illumination systems of modern monitors.

If you sit at a screen 7 to 8 hours per day, it would be worth having a look at the settings of the monitor to try to at least minimise HEV Light exposure.

Unfortunately, most phones and tablets do not come with any way to adjust the output of the screen, which means there is no way to reduce the blue output- which is why many spectacle lens manufacturers are now offering “Blue Control” Antireflective coatings.

With children and teenagers spending hours staring at laptops, tablets and phones, it may be advisable to consider a protective coating for them.
