non prescription progressive glasses

Columns that stay open on every factory reply

Specification choices that remain open should stay open on every reply. If a factory offers a substitute corridor length or frame material, record it as a separate offer rather than a silent upgrade. Verify coatings 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

Corridor length and fitting height change cost and wearer comfort. If the buyer needs non prescription progressive glasses for a display sample program, a reply that only says “progressive” without plano confirmation is not the same scope. Frame material and coating status must appear when those fields change cost.

Base clear progressive lenses versus coated progressive lenses also change cost. Coatings are not included unless the supplier writes them in. Keep each finish on a yes-or-no column so a cheaper uncoated pair is not mistaken for a coated pair. Freight scope and packing unit still need their own confirmation before the landed cost is compared.

Selection trade-offs on the same row

Non prescription progressive. Plano progressive corridors for try-on or display when written. Prescription progressive. Acceptable only if the buyer supplies sphere, cylinder, axis and add, plus pupillary distance when the fitting height depends on it. Uncoated stock. Lower unit price when the buyer adds coatings later. Coating included. The finish package must appear on the quotation before the landed cost is compared.

Marked millimetre size. Lens width, bridge and temple can be checked on the sample. One-size claim. Only acceptable if the buyer agrees the fit range is unspecified. High index or polycarbonate progressive blanks are different cost lines from CR-39 when the quotation names the material; do not treat those materials as interchangeable without a restated row.
