Tensile Strength
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.
