i have a question ...

the phrase "used to" ... i faced a sentense with
"readers used to seeing"
...
i find gerund (seeing) after used to is a bit strange
:s
...

i searched for it and found it correct ...
in both cases ( infinitive & gerund) or what ???

and do u know the certain conditions of using infinitive or gerund after used to
??
و جزاكم الله خيرا :>
