David Greenberg is a former board member of the New York Mercantile Exchange who lost friends and colleagues in 9/11. A few years ago, he was at a restaurant when his eye began itching. He placed a few drops of water from his water glass into his eye, which led to a massive infection. The infection spread, necessitating a cornea transplant. Four days after the transplant, as he was pulling a t-shirt off a hanger, the hanger flung out, coming off the rod and hitting David’s eye. He tore his new cornea, optic lens and pupil. 

After a year of reconstruction, David was able to see with the help of the PROSE lens. Then suddenly in August of 2014, he had a retina detachment, then another and another. His doctors had no choice but to take the new lens out and replace it with a long-term silicone bubble. David lost vision in his right eye for a year and is hoping to regain partial sight in years to come. During this time, he will be wearing an eye patch over his right eye.

As a futures trader, David is well used to ribbing on the trading floor. After being the focus of a few remarks about his new "Pirate Patch," he decided to make something positive out of a bad situation.
