I am not sure what tool or browser add-on is giving those numbers, but I don't think they are accurate.
I checked multiple other tools and the search volume is basically non-existent.
If you manually look at the results in Google they are virtually all sentence fragments of parts of longer terms, such as -
VSP Vision Care is Your Source for Eye Care Information
For Eyecare Professionals | Essilor
Contact | Center for Eyecare
Accepted Insurance at Maumee Center for Eyecare
Maumee Center For Eyecare
Financial Aid for Eye Care | National Eye Institute
CDC Addresses Need for Eye Care with New Surveillance System
I don't really think the term makes a lot of sense as a stand alone term.
