What eye condition has Halle Berry & Rihanna both incurred?

Halle suffered an eye injury during her shooting of 007 movie Die Another Day, when a fragment of a smoke grenade lodged in her left eye after a series of stunt explosions.  James Bond, played by Pierce Brosnan was shooting down a helicopter during this scene.  Doctors at a local hospital removed a piece of shrapnel, and while her eye was inflamed and red, she suffered no permanent damage and was soon back on the set.

Rihanna allegedly suffered a scratched eye due to an abusive relationship, thus causing her to wear a patch to cover her red and sensitive eye at the 2008 American Music Awards.

Halle & Rihanna both suffered an abrasion to their corneas, which can cause significant pain, redness, tearing, and light sensitivity.  Medical treatment should be sought right away for this condition.
