Thank you so much for the direction. I tried it out and it works beautifully! I am sure I will use this frequently. More annoying questions to come!
:D
Where do I find these formulas? I have been away for a while and was unaware that I could download anything.

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...
Hey gang. It's been a while, but I am back! Safilo has a fantastik website that, while slightly more busy than Marchon's, does have an online catalog, shows prices, allows you to mark frequently...
I think part of the AR coat for kids equasion is the lab. My lab offers a lifetime warranty against scratching if Crizal, Alize, UTMC, or the like is chosen. The child can come back once a month for...
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.
Ikon44, the turn around time for Bolle in the U.S. is about two weeks. They use Sola labs to create their prescripsion lenses. I've not had any more complaints regarding Bolle than any other brand,...

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...
The data on the strength of this lens over polycarbonate comes directly from Seiko.
I am totally unfamiliar with Ontario geography. I can do some web browsing and see if I can't find out for you. Thanks.
Hello OptiBoarders,
I am trying to find a great optician in or near Oakville, Ontario. I am in Tennesse and have a customer who lives in Oakville. He visited me and purchased several pair. He has...
I am, once again, searching for answers on the greatest optical info site around. I work in a medical center and one of the doctors here, a low vision specialist, is requesting information on...
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. :)
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...
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...
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...

Right here on our fabulous OptiBoard I found a post regarding the MR-10 high index resin from Seiko. This is said to be very light weight, thinner than Trivex and from all I have been able to get my...
As was stated earlier, this answer is subjective, but my lab of choice is Walman Optical. I use the branch in Evansville, IN, but they are accessable anywhere in the country. The people are super...
Thank you Diane, once again, and thank you to everyone who replied. I have ordered the book from the NAO (they are no longer stocking the book and selling what they have on hand for $10 apeice) as...
Thanks Diane for the extremely rapid reply. When I spoke to the NAO I was given no indication that such an item existed. I was simply told, 'No, we don't offer a review course for the Advanced ABO"....
