Commission Delegated Regulation (EU) 2025/1920 of 12 June 2025 amending Regulation (EU) 2017/745 of the European Parliament and of the Council, as regards the assignment of Unique Device Identifiers for spectacle frames, spectacle lenses and ready-to-wear reading spectacles
Issued by European Commission
· Directorate-General for Health and Food Safety
**Executive Summary**
Commission Delegated Regulation (EU) 2025/1920, issued on June 12, 2025, amends Regulation (EU) 2017/745 regarding the assignment of Unique Device Identifiers (UDIs) for spectacle frames, spectacle lenses, and ready-to-wear reading spectacles. This regulation introduces the concept of "Master UDI-DI" to group similar devices under the same UDI, aiming to reduce the proliferation of UDIs. It comes into force twenty days after publication in the Official Journal of the European Union and applies from November 1, 2028, although manufacturers may implement the Master UDI-DI system before this date.
**Key Points / Main Content**
* **Purpose:** Amends Regulation (EU) 2017/745 to revise UDI assignment for specific optical devices.
* **Master UDI-DI:** Introduces the concept of a "Master UDI-DI" for grouping similar spectacle frames, lenses, and ready-to-wear reading spectacles under a single UDI-DI.
* **Spectacle Frames:** A UDI-DI will be assigned to spectacle frames sharing the same design parameters, including the horizontal boxed lens size ("Master UDI-DI"). A new Master UDI-DI is required if the combination of design parameters changes.
* **Spectacle Lenses:** A UDI-DI will be assigned to spectacle lenses sharing the same groups of mean sphere power, addition power, and similar vision impairments ("Master UDI-DI"). A new Master UDI-DI is required if the combination of design parameters changes.
* **Ready-to-Wear Reading Spectacles:** A UDI-DI will be assigned to ready-to-wear reading spectacles with the same combination of design parameters, including horizontal boxed lens size and lens spherical power ("Master UDI-DI"). A new Master UDI-DI is required if the combination of design parameters changes.
* **Entry into Force and Application:** The Regulation enters into force twenty days after publication in the Official Journal of the European Union.
* It applies from November 1, 2028.
* Manufacturers may assign a Master UDI-DI before this date.
**Impact Analysis**
**Manufacturers of Spectacle Frames, Spectacle Lenses, and Ready-to-Wear Reading Spectacles:**
* **Impact:** Will need to adjust their UDI assignment processes to align with the Master UDI-DI concept, potentially reducing the number of unique UDIs required.
* **Action Required:** Implement changes in internal systems and adapt technologies for printing and scanning UDI carriers to comply with the new Master UDI-DI requirements, and may choose to implement the new system before November 1, 2028.
**Eudamed Database Administrators:**
* **Impact:** Potentially a reduction in the number of UDI-DI data entries related to the above-mentioned devices.
* **Action Required:** Ensure that the database can handle the Master UDI-DI structure and accommodate the necessary updates.
**Economic Operators:**
* **Impact:** May need to implement changes in their internal systems and adapt technologies for printing and scanning UDI carriers.
* **Action Required:** Adapt technologies for printing and scanning UDI carriers and change their internal systems.

of 12 June 2025
amending Regulation (EU) 2017/745 of the European Parliament and of the Council, as regards the
assignment of Unique Device Identifiers for spectacle frames, spectacle lenses and ready-to-wear
reading spectacles
(Text with EEA relevance)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical
devices, amending Directive 2001/83/EC, Regulation (EC) No 178/2002 and Regulation (EC) No 1223/2009 and repealing
Council Directives 90/385/EEC and 93/42/EEC(1), in particular Article 27(10), point (b) thereof,
Whereas:
(1) Regulation (EU) 2017/745 provides for a Unique Device Identification (UDI) system for the identification and
traceability of devices. Before placing a device, other than a custom-made device, on the market, the manufacturer is
required to assign to the device and to all higher levels of packaging of the device, a UDI. The UDI comprises of a
device identifier (UDI-DI) and a production identifier (UDI-PI). The UDI-DI is one of the core elements which a
manufacturer needs to provide to the UDI database in the European database on medical devices (‘Eudamed’).
(2) A UDI-DI is assigned to a specific model of device and manufacturer. Spectacle frames, spectacle lenses and ready-to-
wear reading spectacles, also called ready-made reading spectacles or ready readers, are available in many variants due
to the high number of design (clinical and non-clinical) parameters and construction variants that characterise them.
As a result an UDI-DI is assigned to each such variant. This individualisation at UDI-DI level results in a proliferation
of UDI-DIs to be assigned to similar spectacle frames, spectacle lenses and ready-to-wear reading spectacles and a
disproportionate number of UDI-DI data entries in Eudamed relative to the safety risk associated with these products.
(3) Developments at international level and discussions with issuing entities, industry and other relevant stakeholders,
and Union competent authorities for medical devices, together with the technical progress, suggest that certain
highly individualised devices such as spectacle frames, spectacle lenses and ready-to-wear reading spectacles that
have the same design (clinical and non-clinical) parameter combinations are more appropriately grouped under the
same UDI-DI (‘Master UDI-DI’). In order to avoid assignment of different device identifiers to very similar spectacle
frames, spectacle lenses and ready-to-wear reading spectacles, a solution is therefore needed for UDI-DI assignment
to these products.
(4) Regulation (EU) 2017/745 should therefore be amended accordingly.
(5) In order to comply with the amendments made by this Regulation economic operators must implement changes in
their internal systems and adapt technologies for printing and scanning UDI carriers. The application of this
Regulation should therefore be deferred,
