I need to compare the 2 materials. What I think I know so far is that Trivex is more difficult to work with, harder on finishing equipment, but more durable.
Changing here to the term HiVex from 1.56, understanding that HiVex is a newer iteration than the old 1.56
HiVex seems to have better ABBE value than Trivex.
Both are 100% UV and HiVex UV++ seems to have some visible blue absorption similar to Hoya's version.
Saw this last version yesterday at Vision Expo. Is somewhat yellow, no where near as yellow as Blue Tech
Soooooo, here goes:
1. correct any errors above please
2. are there any other negatives lurking out there for either material?
3. any other positives for either?
4. are either materials environmentally safe (recyclable without too much trouble, lenses, pieces and swarf, and is machining both of them safe)?
5. Regarding tintability and scratch resistance, are either or both tintable before hard coat, and after hard coat, is there much difference in tintability and in scratch resistance.
6. any other comments will be appreciated.
