eye lenses

Assalam0alikium actually my eyes sight is weak and even with glasses i can't see properly so doctor have suggested to wear contact lenses that make my vision clear. lenses are weared at the start of the day and removed when i get to bed late night, so they are in my eyes whole day even when i do wudhu. my question is that when i do wudhu while wearing lenses, is it permissible and my wudhu is completed or not? one more information for you that lenses are not very easily removed and weared. i know washing face is farz in wudhu and whole face should be wet, is that means eyes from inside should be wet as well? please guide me. Wsalam
