Prescription inserts versus glazed lenses
The checker distinguishes how prescription correction is provided. A matching number does not mean two routes have the same fitting, ordering or replacement requirements.
Compiled by Sam, Swansea Digital.
| Route | What it describes | What to confirm |
|---|---|---|
| Glazed lenses | Prescription lenses fitted into the frame. | Exact frame, lens type, provider, and whether the lenses must be selected at purchase. |
| Prescription insert | A separate corrective insert behind the device optics. | The insert version, compatible device, fitting measurements and complete price. |
| Clip-on prescription frame | A separate prescription frame attached to the device. | Attachment compatibility, lens limits and fitting requirements. |
| Built-in dial | A device adjustment with its own published range. | What the adjustment corrects and whether other prescription needs require a different route. |

A frame-only price does not include an insert or prescription lenses unless the provider says so. The model pages distinguish frame price, lens surcharge where published, and checked dates. Confirm the final total before ordering.
Find the source for your model
Open a model guide and read the named route and source. Country, frame version and provider restrictions all matter. The checker applies the recorded rules to your entered values; an optician confirms the final fitting.
