[Resolved]  Crizal — Black mark on left lens does not go away

Address:

42 St. Marks Place

I purchased these lenses from Anthony Aiden Opticians located in Manhattan New York November 21st. After I picked up my glasses on the 1st of December. I went home to clean them because there was some skin oil on the lens. I used a very mild soap mixed with water .
My Optician said I can clean with a little soap and lukewarm water.
After i did this when I was drying them off with a soft cloth that came with my eyeglasses a small black mark appeared on the left lens. It does not go away. The lenses are new this should not happen.
I am not complaining the vendor were I brought the glasses from but the lens should not marred after one wash.
