The BO is there with the minus lens, it's just more difficult to notice. Spot up the OC and draw a vertical diameter line through it to the edges and you'll better see it. It's slight, only about...

Never heard of them.

It's common procedure.

This is probably old news to many, but after doing this for too many years a light bulb went off.

We should have an annual inventory plan formulated at the beginning of the year, which can take...

Sample size is too small. Who knows? Can the patient be more specific?

I like Lensman's idea. A slightly large lens torqued into a metal frame? Causing a toric front and back surface?

Trivex

Call Three Rivers up the street and see what they can do.

Barrel distortion from high plus?

Lots and lots about POW before it became well-known.

I think I remember teaching myself that any lens tilt, due to the lens's thickness, requires the BI prism. It is indpendent of lens power. Just a slabby thing. But yeah, 1/2^ is what we always use...

I really hesitate to seem contrarian, because I'm not. Can we get something approximate in a design such as Shamir's Attitude Sport?

I would like to thank Jeremy for posting so dilligently on this lens design.

Jeremy, I hope I'm not going over old territory, but can I characterize the design this way?

First of all, it seems...

This is a matter of state law. There are reasons you can limit quantity in my state.

This is likely a consumer question.

I think that the doctor should use the power of the exam chair and the fear of blindness to drive patients to their optical.

What I do is say "Mrs. Jones, your old glasses' prescription is running...

DanLiv is the best.

My advice: a mirror of some sort covers a lot of sins.

I don't like the idea, but I am using a lot of standard PALs for task, too. It's a cheaper option, sometimes. It gives a wide screen panorama. Use +0.50 for an "indoor PAL" effect or +1.00 for a...

THat's a really neat link.

It's a little older, I think, because optician-compensated wrap eyewear is kind of a thing of the past.

You can just order the "branded" stuff like Attitude SV and...

It's been done. It's probably underutilized.

I'm not sure the duration of effect on a tear film, though. It would probably be neutralized before any significant antiseptic effect.

It's...

Not to hijack, but do you all put a flash coat on the front of your polars?

Well, NAICITPO, you're right because my optician just had to send back some CR39 lenses for more tint because they're "not dark enough" and now they're "too dark".

What is absolutely true, though, DanLiv, is that any error in refraction comes out when the pupil enlarges in night driving, of course. (That's one reason I like to refract dilated when possible.)

Nice research, RM!

Nicely said, DanLiv.

For the record, I do not think the pupil size in sunglasses increases very significantly.

I'm not understanding the "polarized always" movement. Can someone sell me on that?
