A layer of liquid crystal sandwiched inside each lens alters its refractive properties according to the current applied, adapting the focal length according to where the wearer is looking.In the 2030's future that I imagine in the first Suki series, this was one of the unstated features of the glasses people wear. I addressed the LCD virtual 3D displays and virtual keyboards in the glasses.
Sarah and Suki took the concept into contact lenses and I ran with that for the new series, Suki With A Twist.
