Custom transition lenses: measurements that keep quotes comparable

Specification choices that remain open should stay open on every reply. If a factory offers a substitute index or activation color, record it as a separate offer rather than a silent upgrade. Verify coating exclusions and packing before treating a lower unit price as the same scope.

Optional budget uses amount or range, currency, and per-unit or whole-order basis. High-end, mid-range, budget or undecided preference is a buying note, not a verified rating. Continue from inquiry options or send the aligned row through the contact form.

What to verify before accepting an alternative

Grey activation versus amber activation changes outdoor appearance and must stay on separate columns. If the buyer needs a stated refractive index, a reply that only says “standard” is not the same scope. Single-vision transition lenses versus progressive transition lenses is another split: corridor notes and add power must appear when the line is progressive.

Base photochromic lenses versus polarized transition lenses also change cost. Anti-reflective coating, hard coat and polarization are not included unless the supplier writes them in. Keep each coating on a yes-or-no column so a cheaper clear pair is not mistaken for a polarized outdoor pair. Polycarbonate versus CR-39 blanks also shift impact and weight notes; treat those materials as separate offer lines. Freight scope and packing unit still need their own confirmation before the landed cost is compared.
