ok thanks

No work has been done on this script it is his full multifocal script he has distance glasses from this script..

I have a client with script
-2.50 -0.75 78 +1.75 +2.25
-2.25 -100 100 +1.75 +2.25

He want to have distance at the top and computer at the bottom to read the dash.

I have done heaps of...

Me thinks its the latter

No changes at all, same frame, same script same lens.

First pair good second pair no good third pair remade good??????

Can single vision lens be tested on the edges for blur?

I have a client that said he could only see through the middle of the lens and that the edges were blurry.

We replaced the lenses and...

This is an extended reader not a trifocal.

Should the sphere be +2.25 or +3.00 leaving either +1.50 or +0.75 for the reading section?

I have a script with the readings

sp cyl Ax ADD INT
+1.50 -0.75 100 +2.25 +1.50

does this mean a shift of +0.75
Thus making the sp +2.25 ?

Optical store is saying...

thanks

I have a frame with 28mm lens depth can I have a freeform progressive in that frame

What is the minimum frame height for a freeform lens please

What I am looking for is a way to check segment height of a pair of glasses

Is there a way to check if the lab has put the focal point in the requested place eg from the marks on the lenses?

Also can only the full PD be checked from the marks and not the individual lens?...

thanks guys

Hi guys,

I am confused I have a client with a script of Plano ADD +1.00 Optometrist has asked for 0.75 shift

This would only leave +0.25 ADD
are there any lenses with +0.25?
How can this...

that changes the total power

When you start with the TOTAL reading power, and then subtract either .75 or 1.25 to get the intermediate power on the top what is left on the bottom?
example RX +2.00 Add +2.00

Can High prescriptions can the lenses be thinned (ground down) ?

RX is +1.50 with an ADD of +2.25 he wants computer Reading glasses

so my original question if he has a +1.75 int single vision computer would be +3.25 how do we split for computer/Reading ?

not a trifocal

not using access lenses so if he has a +1.75 int single vision computer would be +3.25 how do we split for computer/Reading ?

but the script is +1.50 ADD +2.00 and the optometrist has said to use is +2.25 on the bottom and +1.50 on the top that doesnt make sense to me should it not be +1.5 on the bottom and +2.25 on the top...

I am confused,

I have been told to make an extended reader for computer/Reading you shift half the ADD

example script Sphere +1.50 ADD +2.00 = +2.50 on the sphere +1.00 on the ADD for the...

How about a short corridor for the larger frames?
