Cool.
But It is more fast draw the pattern on the lens and go to hand edge the lens.

IMHO If it is tint dark they will never come back 100% clear.

what kind of lens neutralizer have you used?

thank you :smug: very helpfull

IMHO

the yellow blocks the blue but it is hard to say how much it cut without a Spectrometer.

Different batch of old lenses may have different result for sure.

I prefer a new lenses coated...

I think a lens with hoa correction and 1/100th Diopter resolution do not make great difference for most the patients..even high minus

infrared Block ar coating
Other the ar that can cut hev blue light anche ar that can block the back uv reflection now we have ar that can block some IR light for an healty eyes in clear lenses.
...

Anyone have tips for nystagmus patients?

you need a tracer like standard edgers.

but you not need a blocker anymore

Santinelli is good if the edger is in good shape.

I like more the grey color of the sensity

Yes is a special younger product in ft28 link

the tansitions trivex layer would be thin on the front so I don't know about...

good but nothing special most lens lab have the same technology.

You are right but shape matter too if you want be accurate.

I understand:biggrin:.
honestly I never have an issue with sensity either transitions.
Sensity green is more emerald green is lighter than the g15 style of transitions.
sensity brown and grey are...

Barberini Italy? are u sure? vinny?

anyway I think Mj is poly and some trivex material on high end stuff.

In Italy too.
So I don't know if the sensity vsp is the same product hoya sells in eu/jp.

sensity use a special spin coat tecnology by hoya it is different from liferx

sensity is a very good...

@ Robert Thanks for explanation on aspherics.

Happy for you tallboy.

Maybe they apply a removable antislip top coating on the ar like crizal lenses and this batch went wrong and does the opposite? who know.

1.74 have low abbe value

If you do not center Aspheric lens design through the eyes center of rotation the lens will not "correct" spherical abberation.


the aberration product by an error on...

My 2 cents... The old glasses of your patient was spheric or aspheric design? Some people don't "digest" aspheric design.


aspheric design you have to set fitting heigh on the center of rotation...

@Tallboy what about the life of your nidek pliable cup? I say it because today one in my hand..it seems in good shape but crack in the edger...I use them too much before replace:cry: so... slipage......

I think nupolar technology is less sensitive to delamination due the film is inside the polymer.

Also I will go with trivex

The transitions lenses price may be different from different labs try to check other suppliers.

Hoya have "sensity dark" a similar technology to transitions extra active.

I hope this help :)

The best option is a water recycling system with filter.
It is more ecological and money saver for water.
