Japanese eyewear brand Zoff has two ranges of PC spectacles that cut out blue light to different degrees.
The lenses are layered with what the company describes as a "special coating" that not only reduces glare, but also cuts a percentage of blue light within the 380 nanometres to 500 nanometres range, some of which may cause digital eye strain.
