Sioux Falls Rehabilitation Center for the Blind student, Trenton Rowland, 28, of Sheridan, Wyo., who has retinitis pigmentosa--a degenerative eye disease that causes severe vision impairment and often blindness--works using an iPhone with JoMarie Laughlin, computers with assistive technology instructor at the Rehabilitation Center who is also visually impaired herself, during a computers with assistive technology class on Wednesday, April 9, 2014, at the Rehabilition Center in Sioux Falls. Laughlin said that Apple products are more accessible for the visually impaired. Rowland, who just started classes at the rehabilitation center on Monday, April 7, 2014, hopes to go back to college after his time at the Rehabilitation Center for human services so he can one day help visually impaired veterans, he said.
