Community Service Clubs
Most service clubs do not have established programs for funding medical equipment but as a last resort will often help out people who have exhausted other avenues of funding and are still short of the total needed. When applying to a service club for funding it's a good idea to have a record of the funding sources you have already approached and the result of each. (source)
For instance the Lions Club has an assistance request program for individuals with severe vision or hearing loss. The program stipulates:
For nearly 100 years, Lions Clubs have provided resources for individuals who are blind or who have severe vision or hearing loss worldwide. A local Lions club in or near your community may sponsor a program that provides assistance for the purchase of eyeglasses, hearing aids, health-related services, scholarships or educational needs. For more information about this program please visit this website.
