We have horses and flies near our house-insect repellents are indeed useful.
A horsefly attack usually involves only one insect and (steel yourself) if
you let it land there is a useful interval between skin contact and the
bite.
Let it land then blat it. This removes the immediate nuisance and lets you
get on with whatever you are doing.
Co-operating with a friend is also a useful way of dealing with them, as one
person can look out for the other.
Midges can attack en masse when this advice does not apply.

My garden (and home) is being invaded by horse flies (three horses are
stabled in the field next door) and their nasty bites make venturing
out into the garden quite hazardous. Is there anything I, or the horse
owner, can do to reduce their number?

Not reduce their numbers but to stop you and yours being bitten try using
an insect repellent containing DEET. Most good outdoor shops will stock
the real stuff if your local chemist doesn't.
