Reading this record
The practice bills under the legal name Family Eyecare Specialists PLLC and registered William T Black as its trading name, so an insurance statement may show a name that does not match the sign on the door. 4 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 refreshed in March 2026, putting it among the 27 of 118 Boise City records updated in 2024 or later, so the contact details are more likely to be current than most of this metro.
For local context: Caldwell holds 13 registered eye care practices in this snapshot, 12 of them optometry and 1 ophthalmology, in ZIP codes including 83605. 2 of them took an NPI before this practice did. The closest is Vision Quest Medical Center, PA in Caldwell, 0.0 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 Idaho 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 William T Black. 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 118 practices on the Boise City page give you the full local field to call around.
