That’s because when staring at those devices, you may be blinking somewhere around 50 percent less often that you do when looking at other everyday things, says Dr. Christopher Starr, an associate professor of ophthalmology at Weill Cornell Medical College.

Hawk-Eye’s vision extends to soccer and beyond

The eyes of these animals were greenapparently a transition color suitable for neither the full light of summer nor the full dark of the true, on-like-Donkey-Kong winter typical of rural Norway. In another experiment, the researchers removed the golden tapetum lucidum of summer reindeer and laid them out for observation. They then applied pressure with a small weight and watched the samples immediately turn deep blue. When the weight was removed, the blue ebbed, and the gold slowly returnedthough the eye slabs lay disembodied on a slide.

Glaucoma glaucoma is a leading cause of blindness. The patients generally have no symptoms, until the disease is advanced and difficult to treat. Glaucoma is diagnosed by an eye doctor who measures pressure in the eye, examines the optic nerve in the back of the eye, and performs visual field tests. If diagnosed early, the disease can be controlled and progression slowed down. Age Related Macular Degeneration (ARMD) ARMD is a common cause of blindness in adults.

Hawk-Eye is now working with Dutch soccer authorities to take technology in soccer a step further with a full-blown trial of video refereeing. The concept has been used for several years in sports such as rugby union and American football; Hawk-Eye aims to reduce the reliance on TV broadcast output to come up with quicker and clearer answers. Its Officiating Replay System allows an extra referee to quickly monitor multiple TV feeds from the broadcaster before they are aired, to review contentious calls to, say, award a penalty kick or disallow a goal for offside.
