Do memory care facilities take people who are also experiencing vision loss?

MIL with dementia and glaucoma recently had a bout with shingles. Her vision has suddenly taken a turn for the worst. Apparently shingles can affect the eyes. It is almost like she is going rapidly blind. Are MC facilities open to the visually impaired? If the condition does not reverse we will need to make a change and soon. Seeing a specialist tomorrow, but would like to be prepared. Thanks.
