I'm low income I need help with a exam I live in Indiana can you find a place that can help me.

Call an area Lions Club. There are probably local optometrists and ophthalmologists who do low-cost or even free exams and glasses now and then (mine do). Or call the reference desk at your local public library for help on this. They will know and will have a list (and will give you the Lions Club number and a contact name)..
