Word of the Day from The Zombie Cause Dictionary is OCCULOEXTENDER.
An OCCULOEXTENDER was developed for use with transplanted zombie eyes. Occuloextenders allow the transplanted eye to detect the infected before overt symptoms express. They are very useful for identifying minions as well. Cadaver zombie vision results in daily pain for the recipient, but wearing an occuloextender helps relieve much of the discomfort. Zombie eyes are very light sensitive, working best in dark rooms. Transplant recipients frequently wear an eye patch when outside or in bright lights. Doc Ruger has a transplanted zombie eye and can be frequently seen wearing an occuloextender.
