Setting a world record at the Olympics is an impressive feat. It becomes even more impressive when the competitor is legally blind.
What Im Dong-hyun of South Korea did in London on Friday borders on nearly impossible.
Legally blind, Im set the world record, the first world record set at these games, in the one sport where eyesight seems to be the most important tool - archery.
The 26-year-old, who has 20/100 vision, broke the 72-arrow mark with 699 points.
This was no fluke, however. Im also took place in the team competition, where the South Koreans broke the world record in that event as well with a score of 2,087 points on 216 arrows.
Im had previously set the world record at the 2004 Summer Olympics in Athens and was a member or the 2004 (Athens) and 2008 (Beijing) South Korean teams that took home gold.
