One of the effects of the police's policy of shooting directly at protesters' heads in the last 3 days has been that many of them have lost an eye.

Ahmad Harara, a dentist, lost one eye on January 28 and one three days ago, on November 19.

Over 11,000 people were injured (and 800 killed) during the January 25th uprising, and no one, to this date, has been held responsible. It's this combination of brutality and impunity that has brought people back to the streets.

And protesters are devising ways to protect themselves. Some have industrial-style goggles. Others are sharing ingenious ways to make home-made visors.

Just another indication (as if one was needed) of the extraordinary resolve of Egyptians to see their revolution through.
