Why is it that H-alpha telescopes do not require special eyepieces?

Coronado has CEMAX eyepieces for use with its telescopes and Lunt also has its eyepiece line which is made of the same anti-reflecting coating material as their etalons. Do they have preferred eyepieces or it is not at all necessary?
