It's probably Pear Midge. We get it some years - someyears it is very bad.
Sorry but I've no suggestions as to what to do about it.

It is definitely Pear midge damage.
We have pear midge on a Williams Pear, could never control it so asked the
RHS pest dept! there are apparently no approved chemical sprays, they
suggested the removal of all effected pears (obviously have much smaller
pear trees than us!) but the other advice was better, plant different
varieties as pear midge is a very short season pest and if a pear flowers
just a week or two later it can escape damage and this has proved the case
as a nearby 'Conference' is unaffected.
You can also break the cycle by preventing the falling pearlets from
reaching the ground, as those little white maggots have to overwinter in the
ground to complete the life cycle.
I have to admit that we always get some pears on the Williams despite pear
midge and as they don't keep I am not sure what we would do with the surplus
:~)
