SSI is short for Supplemental Security Income. It pays monthly checks to people who are 65 or older, blind, or have a disability and who don't own much or have a lot of income. SSI isn't just for adults.
Monthly checks can go to disabled and blind children, too.
People who get SSI usually get food stamps and Medicaid, too. Medicaid helps pay doctor and hospital bills. To get SSI, you must be 65 or older, blind or disabled. Blind means you are either totally blind or have very poor eyesight. Children, as well as adults, can get benefits because of blindness.
