Kent Cullers


Visual impairment : Blind since birth

The elder child of George Cullers, a physicist, and his wife, Wanda, a college administrator, Cullers was born seven weeks prematurely in El Reno, Oklahoma, at a time when it was standard practice to immerse 'preemies' in pure oxygen. Overexposure saved his life but destroyed Cullers' retinas and left him totally blind.
