Reading this record
The practice bills under the legal name Pamela I. Wu O.D. Inc. and registered Spectrum Optometry as its trading name, so an insurance statement may show a name that does not match the sign on the door. Beyond the primary code the record carries Optometrist, Corneal and Contact Management, Optometrist, Low Vision Rehabilitation and Optometrist, Pediatrics, which is the registry's own signal that the practice covers more than routine work. The entry was last refreshed in August 2022. That is neither fresh nor ancient by the standards of this metro, where 325 of 1,876 records were updated in 2024 or later and 1,079 predate 2020.
For local context: Irvine holds 52 registered eye care practices in this snapshot, 39 of them optometry and 13 ophthalmology, in ZIP codes including 92604. 4 of them took an NPI before this practice did. The closest is People Optical in Irvine, 0.5 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 California 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 optometry practice like this
The NPI registry holds no prices, so nothing here is a quote from Spectrum Optometry, and independent optometry practices do not publish fee schedules. Customers report paying $120 to $200 at this kind of practice without insurance, which is a reported band rather than a published price. The nearest published figure is $95, the median starting fee across the 1,280 US retail optical stores that print one (30 September 2026), and Medicare pays $149.64 for a comprehensive new-patient exam (CPT 92004). Ask Spectrum Optometry for its self-pay price.
Ask two things when you call: whether the quoted fee includes the refraction, and what a contact lens fitting adds if you wear lenses (the median published contact-lens fee is $129). A comprehensive exam is $80 to $120 at the middle half of stores that print a price. If price is the deciding factor, the 1,876 practices on the Los Angeles-Long Beach-Anaheim page give you the full local field to call around.
