Snake oil! For this to have any effict of value, you'd need to do it about 3 times a day.
That's it! I am getting out of the Optical business.
HEY! He wants a grey A 1.66 or higher index.
Now help me. Why would one need to do such calculations?
Semifinished. It is glass. Let the lab do it. How many times a year you gonna do this. I've been in wholesale for 33 years and done maybe 2.
Santinelli is what you are looking for. It may be the most expensive at first. Have you ever bought a CHEAP pair of shoes?
Tsk tsk! Did you really think you could get quality hard coat AND A/R for $50,000? There are no short cuts for quality A/R. The Ultra Optics is the best Hard coater.
Call Xcell. I think they sell xray lenses. You can groove glass lenses.
CAREFUL!! The "snake oil" put it in the dye pot type "hard coat" does nothing! I know a major lab that uses it. Careful!
The BEST solution if you need a dark tint is not to use poly. Poly does not tint. Only the coating tints. When you tint them dark, the coating gets saturated with tint particles. This...
Try another lab for your high index ar and see if it's better. Your present lab may be trying a cheaper AR system (maybe the $50,000 chemat system. )
Javik,
Here is the problem. When LOTS of optical people on the board here see a consumer here, their first thought is, oh no! another consumer with Enet access. They either buy on line and...
The seg power in the 180= 1.75
(10*.75)/1.75 =4.28 That's how.
10 times the prisim divided by the power equals the decentration.
:angry:
My suggestion would be for everyone to visit a qualified optical store and get a pair of transitions AND a pair of polorized.
And for the optiboard to change the the ad in the top right that...
I some times cool them off to test if they are defective or not. I don't see any point in making over a lens that is going to be the same. (however I have seen a FEW defective transitions. (Less than...
I hope they don't hide this thread. Transitions are a sponser here. Are transitions worth the $$$ or not. For people that have unlimited $$$. I'd say get transitions AND polorized. If it was my...
You know. If the things don't change for you. Take them back and insist on a full refund. They aint worth the money anyway. Get some REAL sunglasses. Polorized is the only way to go. Transitions...
Make a new lens. This should solve the problem. There is probably some type of defect in one of the surfaces.
They do change better in cooler weather. We've put them in the fridge for a while. This helps but I don't know how long this last. Probly until they warm back up. This time of year the labs are...
X cell sells simi finished. Most polorized have to be ground. I know a lab.
I'd be pretty sure they'd last a couple years if you want to push your exam that much. A year easy.
They should last until your next exam.
I have made many of those for dumbass opticians that insisted. They mostly looked like crap. The fromt lens surface has to be somewhat flat and the lens bevel has to be wrapped. Good luck. Please...
