The first competitive swimmer to use goggles was Thomas William Burgess , during his crossing of the English Channel in 1911. His motorcycle goggles leaked water, yet they protected his eyes from water splashes during his breaststroke-only swim. In 1926, Gertrude Ederle also used motorcycle goggles when crossing the Channel. She swam crawl and therefore sealed her goggles with paraffin to render them water tight. Meanwhile, the vast majority of pool swimmers had no eye protection until the late 1960s, which limited their training time due to the eye irritation with disinfectants added to the pool water. When the first commercial goggles were introduced to competitive swimmers in 1968 they were met with limited success because of their fixed and rigid shape. Most swimmers could not fit them to their face and complained about leaks, especially after starts and turns. Only two years later David Wilkie became the first swimmer to use goggles in international pool competitions, at the 1970 Commonwealth Games .  Goggles were first allowed at the Olympics in 1976, and many athletes used them in preparation for the 1972 Games.
