What's the difference between this and a 25mm plossl?

Hi Andrew,
The sales blurb says :
"Coronado CEMAX (Contrast Enhanced) eyepieces are designed to optimize hydrogen alpha solar viewing. The CEMAX 1.25” eyepieces are fully multicoated on all surfaces (including all cemented surfaces, not just the air to glass surfaces) with specially-formulated coating materials that maximize the contrast in the H-alpha passband region. This improves the appearance of subtle solar details by eliminating residual internal reflections and scattered light near the solar disk."
The EP is sale pending to another IIS member by the way.
