Essilor would be the best coatings n anti smudge though their R&D used up the most funds over all competitors , transition owned by essilor , so u all wanna get transition lenses essilor would be cheaper .
Zeiss had thier new coatings for few years only Hoya using their coating for over decades .
If you all wanna have longer lasting lenses from scrathes just avoid index 1.56 will do but 1.60 index costs alot more though .
