This chip could replace rabbits whose eyes are purposefully damaged to simulate dry eye disease in humans.

University of Pennsylvania researcher Dan Huh and his team have developed a model of the human eye that blinks, just as our own eyes do.

Blinking keeps our eyes hydrated and washes away irritants, so this is an important part of the model. The hope is to use this eye-on-a-chip to test drug treatments for dry eye, which could save many rabbits from unnecessary suffering.

Rabbits are often used in such testing, and in 2008, AAVS successfully challenged a patent on rabbits whose eyes were purposefully damaged to simulate dry eye disease in humans.
