    Hello All,
    At one time I had a formula that would allow me to take a standard single vision rx and put in on a higher than standard base curve (specifically for high rap sunglasses) while altering...

    I think you steered him in the right direction. The frame has a nice wrap to it and with a polarized lens, he should be quite happy.

    DRK,
    Thanks for the info about the MR-10 being used by Essilor. I spoke with my Walman rep and she assured me you were correct. She still recommends Trivex for all drill mounts, until thickness...

  16. Seiko 1.67 and MR-10

    The MR-10 resin is the same as Seiko's 1.67. Glad to hear other people are using, many who probably don't even know that both are one in the same. :)
  17. Technical specs

    I have received some technical specifications regarding the strength of the MR-10 resin. The tensile strength of MR-10 is 15500 psi, Poly is 8500-1000 psi and CR-39 is 4390-5945 psi. This makes MR-10...

    Diane,
    The abbe value is 32, so nothing wonderful there. When I first contacted my lab they were unaware of the difference between Seiko's 1.67 and anyone elses. I had to contact Seiko directly to...
  19. MR-10 stronger than Poly

    My info comes from Seiko. I was told the MR-10 resin is 20% thinner than poly and over 50% stronger. Trivex gets too thick. The rx you mentioned may be incredibly light, but will be thicker than...
  20. Trivex is not nearly as thin and the MR-10...

    Trivex is not nearly as thin and the MR-10 material is just as strong (tensile strength and impact resistance). The only points for Trivex would be a higher abbe value and lower price, which...
