Residual blue on bevelled edges... Is this why???

Computer progressive 1.67 thin lenses have a residual blue color on only the beveled edges of the lenses.

They have a standard AR (not blue blocking).
It is noticeable to the wearer in the pastel colored acrylic frame and even worse it clashes. :eek:

Is there a way to get rid of or lessen this?

Or was this possibly caused from something else???

Is it polished?

And or;

Is bevel too heavy?

Alternatively, maybe a light colored edge pen color that compliments the frames colors.

None of the above.

Have you tried to remove the blue color with anything? All off? Acetone?

Power? And why wouldn’t a edge color pen help?

Hmmmm
Lens manufacturer? Wouldn’t happen to be Zeiss, would it?

This came from I believe a MyEyeDoc lab. Patient believes in 1.67 only (poly sensitive) even though it is over contacts and a 0.00 +1.00ish (just leave this be;) add computer progressive with "premium" AR.

I suspect the lenses were surfaced from a foreign lab (Mexico or China-the new norm that many of us mcticians are working with under feudal lords?) and the blanks finished at whatever stateside lab is used. So it had a slip coat on the surface for edging that was poorly rinsed and when it dried it left the blue residue embedded on the unpolished edge.

Can this be the reason lensmanmd?

...As I genuflect to one of OB's guru's who's posts should be must reads for any newbies out there!!!

If it's visible from the wearer's perspective, bump the base curve a diopter or two and/or increase the wrap angle. If it's leftover slip coat, remove it chemically or with a hand stone.

Hope this helps,

(Slightly off topic): Why would the pt want a 1.67 material on a plano lens with an add? I would advise CR39 or Trivex. Unless there is something wonky with insurance coverage, that is.
