Reading this record
The practice bills under the legal name Private Diagnostic Clinic, PLLC and registered Duke Eye Center as its trading name, so an insurance statement may show a name that does not match the sign on the door. 6 locations nationally are registered under the same name, so pricing and policies are likely to be set at group level rather than at this office. The entry was last refreshed in May 2022. That is neither fresh nor ancient by the standards of this metro, where 5 of 53 records were updated in 2024 or later and 31 predate 2020.
For local context: Durham holds 30 registered eye care practices in this snapshot, 23 of them optometry and 7 ophthalmology, in ZIP codes including 27710. 5 of them took an NPI before this practice did. The closest is Myeyedr. in Durham, 0.3 miles away.
None of this is a licensing check. CMS issues an NPI so a provider can be identified in billing transactions, and states plainly that issuance does not ensure or validate that the holder is licensed or credentialed. The North Carolina boards hold the licensing record, and the practice itself is the only source for what it charges today.

What to expect to pay at an ophthalmology practice like this
The NPI registry holds no prices, so nothing here is a quote from Duke Eye Center. Based on this site's own price research, an ophthalmology practice typically charges $150 to $300 or more for an exam without insurance, against a national average of about $136 and roughly $25 once a vision plan pays its share.
Ophthalmology visits are usually medical rather than routine, which changes who pays: medical insurance and Medicare Part B cover a medically necessary exam, while a routine refraction for glasses is normally not covered. Ask whether the visit will be billed as medical or routine before you book, and compare with the 43 optometry practices on the Durham-Chapel Hill page if you only need a prescription.
