    • Harry Chilingueria : Awesome Cindy, I have signed up for the Vision Canada convention and like last year I look forward to the content and will be especially interested in your lecture, can't wait. :)
    • Cindy K : Harry- yes we're doing the Virtual Convention- here's the link:«link» I've also put this on Optiboard under heading of Professional and Educational Discussion Forums.

    • Harry Chilingueria : Oh and Cindy if you guys are doing the virtual convention please send me a link so Icould check out who you got this year as I would be real interested.
    • Harry Chilingueria : Cindy K, no protocal for using the content from this site, but the images are from NIH, which does require a reference back to them, just do a Google search for NEI at NIH and check out their resources. The simulators are from Alcon and they have said as long as it's for a non profit or educational they are fine to use. The posts and content are mostly written by me and compiled from various sources, you are free to use them to your hearts content.
    • Cindy K : What is the protocol here for using material from this site on our association website? Please advise
    • Cindy K : Harry- are you going to do the Vision Canada Virtual Convention again this year? I see what I'm assuming is an old post you made on the subject. The lineup is great this year, and bonus, I get to present one of my favourite lectures there

    Make a Pair of Hot Fingers

    Sunday, June 25th, 2006

    This document goes through the process of creating a set of hot fingers for hidden hinge repair or custom frame making. The parts should cost less than $30.00 total and the knowlege required to complete the project should be basic. The hope is that opticians will learn new ways of engineering their own equipment and offering newer and better services to their clients.

    R=luminous ratio
    Tmax=maximum light through two polarized filters axis in line
    Tmin=amount of light passing through the same filters perpindicular to each other

    Luminous Transmittance Ratio
    R = Tmax / Tmin
