Look for the inputs
Manufacturers describe different approaches to tailoring a progressive lens. HOYA lists individually tailored Hoyalux iD MySelf; Rodenstock distinguishes measured biometric inputs from model-based inputs in its B.I.G. range.
Make the comparison concrete
Ask which measurements are taken, which exact product is ordered and how the result will be checked. A personalised label does not remove the need for accurate fitting or guarantee adaptation for every wearer.
