Reading this record
The practice bills under the legal name Amy Zhang, OD PLLC and registered Myopia Institute of Nova 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 January 2026, putting it among the 136 of 455 Washington-Arlington-Alexandria records updated in 2024 or later, so the contact details are more likely to be current than most of this metro.
For local context: Chantilly holds 8 registered eye care practices in this snapshot, 8 of them optometry and 0 ophthalmology, in ZIP codes including 20151. 7 of them took an NPI before this practice did. The closest is America's Best Contacts & Eyeglasses in Chantilly, 0.9 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 Virginia 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 Myopia Institute of Nova. 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 455 practices on the Washington-Arlington-Alexandria page give you the full local field to call around.
