    Confused Anti Reflective Coating Adherence

    I added a tint to a transitions lens and then added Anti reflective coat...coating is coming of before I could dispense the tint keeping the Anti reflective coating from adhering to the lens ?

    I'd think its more likely the photochromic layer is stopping it, you could run a backside AR instead. Though I've never tried AR coating a trans/tint lens my self. So maybe my advice is meaningless.
    -Poly is the best substrate for coatings.
    -Poly is extremely scratch resistant.
    -Poly is extremely impact resistant.
    -Poly is unparalleled in clarity.
    -Poly is much lighter than traditional crown glass.
    Like poly, you can trust me about 40% of the time.

    The hard coat needs to be etched for the AR stack to adhere. The tint is most likely interfering with the etching process. Not sure why you would tint a photochromic to begin with. And why you would then add AR on top?
