Choosing Frames for Progressive Lenses: Height and Fit
Share
A frame can be listed as progressive-compatible without being suitable for every progressive design or every wearer. Before ordering, check both the frame dimensions and how the required fitting measurements will be obtained.
Lens height is not fitting height
Lens height is the physical vertical size shown on the product page. Fitting height relates the wearer’s pupil position to the selected frame and lens. You cannot obtain it by reading a frame specification or copying a height from a different pair.
Different progressive designs have different requirements. Ask about the minimum fitting height for the chosen design and whether it can be accommodated after the frame is positioned properly. There is no single frame-height cutoff that settles every order.
Choose a frame that stays where it belongs
Compare front width, bridge and temple fit with a comfortable existing pair. A sliding bridge or an unlevel frame can change the position of the lens in front of the eye. Our frame-size guide helps you compare dimensions without treating matching numbers as a fitting guarantee.
A product-page example
Moon Square lists 143 mm frame width, 53 mm lens width, 18 mm bridge, 145 mm temples and 47 mm lens height. These are useful frame specifications. They do not supply your PD, fitting height or a prescription-specific approval.
Ask these questions before production
- Which progressive designs are available for this prescription and frame?
- Which PD and fitting measurements are required?
- How will the frame position and fitting height be confirmed?
- Does the design suit the distances I use most?
If prism or a stronger prescription is involved, ask for the combination to be reviewed explicitly. Do not change prescribed values or buy a larger frame solely to meet a number from a general article.
See the progressive buying guide for the purchase decision and the submission checklist for the final order. If a pair is already causing difficulty, use the adaptation and review guide.
