    • 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.

    Tennessee Sunset

    Monday, March 31st, 2008

    It seems as though opticians in TN need our help. The Tennessee Dispensing Opticians Board is up for sunset review. This is a great time to let legislators know that licensed and skilled opticians are needed. Urge your legislators to support the passing of the bills to keep the board. If you don’t live in TN that’s OK you can still make a difference as legislators contact each other so it’s still important you let them know how you feel.

    Out of State Residents
    Tennessee Opticians and residents

    Also please pass these links along to everyone you knwo especially in TN, patients, opticians, students, and family. They all count as constituents and make a difference.

    Tensile Strength

    Sunday, March 30th, 2008

    Tensile strength is very important for determining the strength of lenses in rimless frames. This video shows various materials being tested and the results. We should commend information such as this. This data makes it easier for opticians to make an informed decision when recommending materials to our patients. Apparently this video is a test conducted by HOYA, thank you.

    Tensile Strengths
    Name of Material Index of Refraction Tensile Strength
    Cr-39 1.5 15.6 kgf
    Phoenix 1.53 61.2 kgf
    Polycarbonate 1.58 44.9 kgf
    Eyas 1.6 80.5 kgf
    Stylis 1.67 67.3 kgf
