About Dy Vision Co., Ltd. - Optical Machinery & Equipment Supplier in China

Dy Vision Co., Ltd. is based in China and currently lists five active products in its catalogue. The company groups its offerings under Light & Medium Machinery and Optical Machinery & Equipment, covering devices such as a lens colour machine, an automatic grooving and polishing combination, a trial lens set containing 232 individual lenses, a synoptophore for binocular vision testing, and an ultrasonic cleaner used for optical component cleaning.

The listed products fall within HS‑code chapters that typically include 84 (machinery) and 90 (medical and optical instruments). Each item is described by its functional category rather than by model numbers, allowing buyers to match the equipment to standard industry specifications for optical manufacturing and ophthalmic diagnostics.

Product Range and Specialties of Dy Vision Co., Ltd.

The catalogue includes a lens colour machine capable of applying tint to ophthalmic lenses, an automatic grooving‑and‑polishing combination that integrates precision shaping and surface finishing, a trial lens set of 232 lenses used for refraction testing, a synoptophore that provides controlled visual stimulus for binocular assessment, and an ultrasonic cleaner operating at standard frequencies (around 40 kHz) for removing contaminants from lenses and frames. In the optical machinery sector, lens colour machines are commonly evaluated on colour consistency (ΔE < 2) and maximum lens diameter (typically up to 14 mm). Grooving and polishing units are specified by groove tolerance (±0.01 mm) and polishing grit progression. Trial lens sets usually cover a diopter range from - 20 D to +20 D with base curves between 8.0 mm and 9.0 mm. Synoptophores are classified as medical testing equipment and are measured by angular resolution (often 0.1°) and adjustable optical power. Ultrasonic cleaners are rated by tank capacity (5 - 20 L), power consumption (150 - 500 W) and cleaning cycle time (5 - 15 min).

Trade and Export Information - Dy Vision Co., Ltd.

China is a major exporter of optical machinery and ophthalmic test equipment, with the United States, European Union members, Japan and South Korea representing the largest import markets. Export shipments for the product types listed are normally classified under HS codes 8479 (machines for optical purposes) and 9018 (instruments and appliances for ophthalmic use). Buyers typically require CE marking for equipment intended for the European market and ISO 9001 quality management certification for general machinery; medical‑grade devices such as synoptophores often also need ISO 13485 compliance. Standard export logistics involve FOB terms from ports such as Shanghai or Ningbo, with goods packed in wooden crates on Euro pallets, protected against moisture and vibration for the 20‑ft or 40‑ft containers commonly used for these volumes.

Sourcing from Dy Vision Co., Ltd. - Buyer Guidance

When sourcing from Dy Vision Co., Ltd., buyers should request the latest CE Declaration of Conformity and any applicable ISO certificates before finalising the order. For the lens colour machine and grooving‑polishing unit, obtain performance test reports that include colour repeatability (ΔE values) and dimensional accuracy data. The trial lens set should be accompanied by a lens quality inspection sheet confirming diopter accuracy and base‑curve uniformity. For the synoptophore, verify medical device registration documents and calibration certificates. The ultrasonic cleaner’s specification sheet should list frequency, power rating and tank material (stainless steel preferred). Typical minimum order quantities are one unit per machine type and a batch of at least 100 trial lenses, with lead times ranging from 30 to 45 days after receipt of a signed purchase agreement.

How many products are currently active in the catalogue?

Five distinct products are active in the supplier’s catalogue.

Which HS‑code chapters are relevant for these products?

The equipment generally falls under HS chapter 84 (machinery) and chapter 90 (medical and optical instruments).

What certifications should a buyer request for the synoptophore?

Buyers should request the CE Declaration of Conformity and, if applicable, ISO 13485 certification for medical devices.

What are typical specifications for the ultrasonic cleaner?

Standard ultrasonic cleaners operate at about 40 kHz, have tank capacities between 5 L and 20 L, and power ratings from 150 W to 500 W.

Is a sample trial lens set available for testing?

The catalogue mentions a trial lens set of 232 lenses; buyers can request a sample batch to verify diopter accuracy and base‑curve consistency.

What are common Incoterms used for shipments from China?

FOB Shanghai or Ningbo is commonly used, with buyers arranging onward freight from the departure port.

What is the typical lead time for the listed machinery?

Lead times are usually 30 to 45 days after order confirmation, depending on the specific equipment and any required customisation.
