“ The great thing is that the new Nikon Juveo lenses will be offered exclusively with Transitions Adaptive lenses technology and Nikon ’ s SeeCoat Blue UV anti-reflective coating , which means that they can be worn all day , every day ,” says Patience Cook , director , North America marketing , Transitions Optical .
“ Parents can be rest assured that Transitions lenses help protect their children ’ s eyes from the sun ’ s UV rays and help to protect against harmful blue light from digital devices , screens and especially the bright sun .”
The lenses are also scratch-resistant , anti-reflective and boast anti-static and oleophobic properties .
