    Centre Thickness Formula

    Hi there everyone i'm a Lab Manager from the UK and I have a problem with the assistant store manager at the branch I work at as she is totally bonkers about lens thickness to the point where I can take a lens out the frame and cut myself with the side splattering blood all over the place and dropping down dead but she would still insist the lens is too thick. So to beat the beast I'm trying to compile together some center thickness formula so I can knock her argument down with pure mathematics does anyone know of a website or is anyone kind enough to post the thickness formulas for Spherical, Aspheric and Toric Lenses in both S/V lenses and also if its available for Varifocals as well i know its an awful lot to ask but I don't think I can afford to draw much more blood my life is on the line here. :(

    Thank you in advance may little bunny rabbits bless you and your children for all eternity.

    If that doesn't work then use the lens edge to cut your ears off and you'll never have to hear that dribble. :D:cheers:
