Which organization provides free books for students with visual impairments?

The National Library Service (NLS) is the correct choice because it specifically provides free library services, including books and materials in accessible formats, for individuals with visual impairments. This service is part of the Library of Congress and aims to ensure that people with disabilities, including those who are blind or visually impaired, have access to the same reading materials as their sighted peers. The NLS offers a wide range of audiobooks, braille books, and specialized equipment to facilitate reading, demonstrating a strong commitment to inclusivity in information access.

This option stands out among the others for its direct provision of free reading materials tailored specifically for students and individuals with visual impairments. While the National Federation of the Blind and the American Foundation for the Blind are both organizations that advocate for the rights and services related to blind individuals, they do not primarily focus on providing free books or direct library services to students. The Vision Council of America, on the other hand, is primarily involved in promoting vision care and does not focus on providing reading materials for individuals with visual impairments.
