The ZEISS Authorized Dealer certificate
The certificate issued by ZEISS names Mắt Kính Mạnh Long, the shop's Vietnamese name, as a ZEISS Authorized Dealer, valid until 31 December 2026. It is signed by ZEISS's Head of Vision Care for Southeast Asia and Head of Vision Care for Vietnam.
The shop can order these ZEISS lines: SmartLife Pure, SmartLife Plus, Light 2 (D, 3D, 3DV), SmartLife Individual, Digital Light 2, Office Plus, Office Superb, ClearMind and DriveSafe progressive. Most are made to order rather than kept in stock. ZEISS progressives are made at the brand's lab and take 7–9 days. Who each line suits is covered in ZEISS progressive and office lenses you can order.
The Essilor authorized dealer certificate
The certificate states that Manh Long Optical is the authorized dealer of Essilor (in Vietnamese: đại lý chính thức). It is signed on behalf of Essilor Vietnam by its Commercial Head and is valid until December 2027. It lists the Crizal, Varilux, Transitions, Essentials, Stellest and Elements lines. The address printed on it is "147 Lê Duẩn"; the shop's full address is 147A Le Duan, Cua Nam, Hanoi.
The Essilor lines the shop can order include Varilux Liberty 3.0, Varilux Comfort Max, Varilux Physio 3.0, Essilor Essentials, Eyezen, Transitions Gen S and Stellest, plus Crizal coatings. Essilor progressives are made at the brand's lab and take 4–5 days. Progressive and Eyezen lenses ordered through Essilor's lab come with a warranty card; standard Essilor blue-light lenses come in their sleeve only, with no card. What each line is for is covered in Essilor lenses: where your money goes.
What "authorized dealer" means
An authorized dealer is a shop the brand has confirmed in writing as a place that sells its lenses, for the period printed on the certificate. For you as a buyer, that means three practical things:
- A clear source. Premium lenses are ordered and made at the brand's lab to your own measurements.
- A turnaround you can plan around. Premium Essilor progressives take 4–5 days, ZEISS 7–9 days. Standard progressives take about 24 hours; single-vision lenses are usually in stock.
- A stated warranty. One-for-one replacement within one month for product defects.
An authorized dealer is not a distributor or exclusive representative of the brand in Vietnam, and it does not mean every lens line is in stock. Most premium lenses are ordered after your eye test.
If you are weighing the two brands against each other, Essilor vs ZEISS on the shop's own price list puts them side by side.
What to check when you buy branded lenses
Wherever you buy, a few checks before you pay:
- Ask for the dealer certificate and its end date. A real one names the shop, the brand and the validity period. Manh Long Optical's two certificates are shown above.
- See the lens pack sealed before cutting. Once the lens is edged into a frame, the packaging is the only proof left. With Essilor lenses, the shop opens the seal in front of you.
- For Crizal coatings, try the hidden logo. How to do it is in how to spot a genuine Essilor lens.
- Ask about turnaround and the warranty card for your exact lens line. Not every line comes with a card, and premium progressives are not ready the same day.
Certificates have an end date
Both certificates expire: ZEISS on 31 December 2026, Essilor in December 2027. When a brand issues a new certificate, this page will be updated with the new image and dates. If you are reading after those dates and the images have not changed, message the shop on WhatsApp before you order.
