Yes and actually that subsetting is why we need the richness of the language. A school for the blind is specifically for people who need to learn to make do without hardly any visual input. Assistance for the visually impaired can range from screen reading and braille to large text and high contrast. We also have a lot of definitions for blind and retarded, not referring to personal differences. A duck blind. Retarded bacterial growth. A blind sac. Sometimes people take offense at even these uses.
