I have 4 lenses - one -6.0 diopter lens - two -6.5 diopter lenses & - one -7.0 diopter lens - all fit Oceanic Ion & Ion 2 masks, and I've been told they will another brand of mask.
Cost was $37 per lens, but I'm willing to sell them for not much more than the shipping cost.
May 4 - Having no responses - I've donated the lenses to Diveheart
