cheers!
I’ve seen more hard coats break down lately due to cleaning with harsh chemicals. All because of COVID!
Hi Diane. Welcome to optiboard! Check with https://precisiontooltech.com/optical-catalog/#page=117
I don"t believe a polar grey B exist. I would tint the A darker.
It's always a nightmare to switch over to ANY new system. Good or bad.
I agree with tallboy.
OK I exaggerated. However you would never use a finished lens with this prism amount. Also weaker powers don't adhere to Prentice Rule perfectly. Hence it's a "rule"and not a "law".
You could decenter a finished .25 all day long and never get to a 1.5 prism! Even if you had a 500mm finished blank.
Take it out of network.
Not that I'm aware of.
Is there such a thing as "transitions" paint. That would be a cool concept!
over plussed . no need for hi 1.67
younger optical. Vision ease makes 24mm round.
Still available??????

Keep the lid open at night. The moister can get trapped and force its way into the spindle bearings.
Its whatever looks good and fits good. Be honest. If something looks terrible on them, tell them. Learn the basic rules and then break them when you want.
Thursday night midnight showing!
Wrong.
I would keep it within 3 or 4mm below the pupil unless it is aspheric. Depends on the pantoscopic tilt.
This is the norm for systems to combine prescribed and prism thinning together. Programs can be configured to reduce the amount of prism thinning and also the max. amount of prism thinning used.
Whatever happened to the rxcalculator by Daryl Meister. Not the opticampus one.
I thought the higher the power the more base in prism would be needed and not totally dependent on the "wrap" itself.
The only problem with opticampus program is that it does not calculate the base in prism needed for wrap compensations.
