Reading this record
The practice bills under the legal name Millis Eye PC and registered Rock Optix as its trading name, so an insurance statement may show a name that does not match the sign on the door. The entry was refreshed in February 2026, putting it among the 103 of 632 Boston-Cambridge-Newton records updated in 2024 or later, so the contact details are more likely to be current than most of this metro.
For local context: Millis holds 1 registered eye care practice in this snapshot, 1 of them optometry and 0 ophthalmology, in ZIP codes including 02054. No other practice in the city took its NPI earlier than this one, which makes it the longest-registered address here. The closest is Ilana Orelowitz, O.D. Inc in Medfield, 2.4 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 Massachusetts 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 Rock Optix. Based on this site's own price research, an independent optometry practice typically charges $120 to $200 for an exam without insurance, against a national average of about $136 and roughly $25 once a vision plan pays its share.
Ask two things when you call: whether the quoted fee includes the refraction, and what a contact lens fitting adds if you wear lenses, since that takes a visit to $150 to $370. A comprehensive exam is $100 to $250. If price is the deciding factor, the 632 practices on the Boston-Cambridge-Newton page give you the full local field to call around.
