I ordered a pair of prescription sunglasses online last week, and I just paid several dollars for a anti-scratch coating, but I found their are wave line on the lenses when I put them under fluorescent lamp, why does this happen? what can I do to remove this mave line?

I want to know that if you ordered Anti-scratch coatings for your lenses, this situation may happen it the coating process, I have asked a professional optical expert before I answer your question, and he suggest you can come back to your optician if the wave line effect your vision, Good luck!
