Reading this record
The practice bills under the legal name Peter Eugene Libre and registered Connecticut Glaucoma Associates 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, which is the registry's own signal that the practice covers more than routine work. CMS records this location as a subpart of Peter E Libre MD, meaning it bills under its own NPI but belongs to a larger organization. The entry was last refreshed in April 2022. That is neither fresh nor ancient by the standards of this metro, where 25 of 148 records were updated in 2024 or later and 77 predate 2020.
For local context: Norwalk holds 16 registered eye care practices in this snapshot, 12 of them optometry and 4 ophthalmology, in ZIP codes including 06851. 5 of them took an NPI before this practice did. The closest is Sight MD CT in Norwalk, 0.2 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 Connecticut 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 Connecticut Glaucoma Associates. 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 102 optometry practices on the Bridgeport-Stamford-Danbury page if you only need a prescription.
