Students of all ages as well as many parents are working more and more with screens and all are exposed to harmful high-energy visible (HEV) blue light from digital devices.

While older students may have their own devices, younger children may find a dramatic increase in the amount of time they spend looking at screens at school, which can lead to irritated eyes, sleep disruption and reduced attention span.

InvisibleShield VisionGuard screens are designed to filter out blue light without affecting a device's natural colours. 

InvisibleShield VisionGuard offers four key areas of protection:

▪ Blue light filter

▪ Shatter protection

▪ Anti-bacterial

▪ Smudge-free screen

I have been using one on my iPhone for a week or so now with good effect. However I obviously didn't clean my screen properly (everything is provided for this in the package) as I have two rather irritating dots on the screen. So my advice would be to be absolutely scrupulous when following the the guidance. 

Available from zagg and there are currently discount offers.
