How to choose between its lines
Ask what measurements would be used for B.I.G. EXACT or B.I.G. NORM and what the quoted design includes before discussing other options. If Impression FreeSign 3 is proposed, ask how that order would differ from the alternative being offered. Discuss your indoor, outdoor and driving routine when considering ColorMatic, and request the exact variant name. Keep Solitaire LayR separate from the lens design on your quote. Compare the design, material, measurement appointment, coating and photochromic option line by line, then ask the optician to explain any differences that remain unclear.
Questions to ask your optician
- Would my order use B.I.G. EXACT, B.I.G. NORM or another named design?
- Would a DNEye measurement or visual-sensitivity profile be part of this order?
- Which ColorMatic variant and Solitaire LayR specification are being quoted?
- What follow-up, warranty and remake terms apply to the complete pair?
Fitting and adaptation basics
Ask which appointments and measurements are included in the proposed order, and bring the frame you plan to wear. Pupil distance and fitting height should be discussed in relation to that frame. Explain your usual reading and screen positions, and ask what will be checked when the glasses are collected. Adaptation varies by wearer, so agree on how to arrange a follow-up if a task remains difficult. Review the adjustment, return and remake terms before ordering, including what happens if the practice recommends changing the design after a fit check.

What does Rodenstock mean by biometric lenses?
B.I.G. EXACT uses DNEye scanner measurements, while B.I.G. NORM uses an AI-based eye model from four standard refraction values. B.I.G. EXACT Sensitive also factors in a visual-sensitivity profile. Ask which measurements and design are included. Ask which measurements are included in the quoted appointment and which design will appear on the order. Discuss the chosen frame, pupil distance and fitting height as part of the fitting consultation. Request a written explanation of the proposed specification so you can compare it with another quote without assuming that different measurement descriptions mean the same order.
What are Rodenstock ColorMatic and Solitaire LayR?
ColorMatic is the self-tinting lens family. Solitaire LayR is a multilayer premium coating with UV protection, scratch resistance, antistatic and anti-reflective layers. Discuss photochromic selection and coating selection separately with your optician. Describe how you move between indoor work, outdoor activities and driving, then ask why the proposed combination fits that routine. Confirm the exact names on the order and ask how warranty, return and remake terms apply if you later need a change to the lens specification.
