Reading this record
The practice bills under the legal name Thanh Mai OD PLLC and registered Contact Lens Institute of Nevada 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 April 2026, putting it among the 63 of 330 Las Vegas-Henderson-North Las Vegas records updated in 2024 or later, so the contact details are more likely to be current than most of this metro.
For local context: Las Vegas holds 236 registered eye care practices in this snapshot, 182 of them optometry and 54 ophthalmology, in ZIP codes including 89148. 233 of them took an NPI before this practice did. The closest is Vision Consultants in Las Vegas, 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 Nevada 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holds no prices, so nothing here is a quote from Contact Lens Institute of Nevada, and independent optometry practices do not publish fee schedules.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 Contact Lens Institute of Nevada 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 330 practices on the Las Vegas-Henderson-North Las Vegas page give you the full local field to call around.
