Is acrylic ever mixed into a cellulose acetate zyl?
Is the Charmant Elle collection acetate?
Are they or others coated to keep the acrylic from touching the skin?
I know acetate is petroleum based while zyl is cellulose (plant) based.
Patient says some plastic frames cause an almost immediate allergic reaction on the bridge of her nose. This seems especially true if the frame is has crystal around the bridge.
My Frames Data book doesn't always list the material anymore.
I didn't find this addressed with a quick search so any help is appreciated.
