Optic neuritis classically impairs one's ability to read print or a computer screen, to drive in bright or low light, and to appreciate colors and contrasts. Unfortunately, when optic neuritis results in lasting impairment, there are no pharmacologic therapies to restore vision. Low vision specialists may provide magnifying glasses, brighter lights, and advice to optimize the position of objects at home and in the workplace. Better treatment options are needed to improve visual function.
