Varifocal identity

[Lewy]

Anyone know which brand of Vari has the following marking nasally:

Σ-56

I know the material has to be 1.56 but cannot find who the manufacturer is.

Also does anyone know of a website where different markings are listed?

Thanks,

Lewy

That symbol looks like an Essilor Natural. But don't quote me on that.

It is Essilor Natural, as Optidonn stated.

In the UK this lens is supplied by another of the Essilor groups, BBGR & it is called a BBGR Selective. The Natural lens is no longer available in the UK & France
