Nikon vs Essilor Lenses

Sort of a distinction without a difference.
same polymer, same coating, lenses with front sides and backsides, sold at obscene prices, with nonsense marketing and a roster of names for "different" products which for the most part, are all the same.
somehow and by magic, E can sell a "lower" level progressive on line direct to consumer (frames direct?) with no problem, without eyecodes and visioffices and pixie opti dust.

@Terry They're different in Canada. Flatter base curves. Fitting height 2mm above the cross. No prism thinning.

Here in Nigeria, Essilor market other brands like kodak and techline apart from their Crizal..

For me, i think it is business provided that the brands are good enough to provide their essential services without qualms.
