Leave room for the intended zones
Progressive designs have fitting requirements that help preserve usable viewing zones. ZEISS explains that minimum fitting heights protect access to the near area. A frame that looks attractive in a photograph may not suit the chosen lens design.
Measure the pair you will wear
Discuss fitting while wearing the selected frame in its adjusted position. The useful question is not simply how tall the empty frame looks, but whether the proposed design works with your measured position. Ask the dispenser to explain the measurements being ordered.
Avoid choosing a universal number
Our editorial advice is to ask about the exact lens design’s requirements rather than copying a minimum height from another brand or an online post. If the frame is unsuitable, compare a different frame or design before the lenses are made.
Recheck after fit changes
At collection, ask how the frame should sit and whom to contact if it starts slipping. Note whether moving the frame changes access to reading or screen vision. Bring the actual pair back for adjustment rather than estimating new measurements yourself.
