No, it's just a normal spousal visa, based on my husband being an EEA national working in the UK.
Actually you don't have a spousal visa at all, you have a 5-year EEA Residence Permit.
Spousal visas are part of the UK immigration laws and are only issued to family members of UK citizens. As your husband is an EEA national, you came to the UK under the EEA immigration rules instead, not the UK immigration rules.
However, due to Brexit... in 2021, EEA Residence Cards were replaced with the EU Settlement Scheme/Settled Status, and if you held a 5-year EEA Residence Card, in order to remain in the UK, you had to apply for the EU Settlement Scheme by the deadline of 30th June 2021.
If you or your family are from the EU, you might still be able to apply to switch into the EU Settlement Scheme after the deadline, if you can meet the criteria to do so.
See here for more information and to find out if you are still able to apply for the EU Settlement Scheme:
