According to a wildly fascinating article in the July 1982 issue of American Cinematographer, the glowing quality of the replicants' eyes was achieved live, on set, during principal photography, using a relatively simple technique. The filmmakers used a two-way mirror 50 percent transmission, 50 percent reflection and placed it in front of the camera's lens at a 45-degree angle. This is better known as the 'Schufftan Process,' a technique invented by Fritz Lang for Metropolis, which happens to be one of Blade Runner's visual touchstones. Next, the filmmakers shined a light into the mirror in the same path of the lens so that it would reflect into the eyes of the subject. The lighting device, also known as a pup, was very small and included a dimmer which could adjust the intensity of the light when necessary. The result being: light is reflected from the mirror into the subject's eye while not being photographed directly in the camera. The American Cinematographer article pulls from an interview with Blade Runner cinematographer Jordan Cronenweth, who describes how sometimes the crew would use very subtle gels to add color to the eyes. This coloring can be seen most clearly with the replicant owl in Tyrell's office. "Often, we'd photograph a scene with and without this effect," Cornenweth recalled. "So Ridley could have the option of when he'd use it."
