How do Morrow e•Progressive electronic lenses work?

A thin liquid-crystal cell is laminated inside the lens. When the wearer needs near vision, a low-voltage signal changes the orientation of the liquid-crystal molecules and the refractive index of that zone increases, adding reading power on demand. When the boost is off, the lens behaves like a conventional distance or light-addition lens with clean, undistorted optics.

What is new in the Gen 4 e•Progressive lens?

Gen 4 was redesigned from real-world wearer feedback. It offers an intermediate vision area three times larger than the previous generation, a near field of view that is 33% wider, fewer visible lens markings and smoother, more natural power transitions.

Why do wearers adapt faster to Morrow lenses than to standard progressives?

Because the reading power is supplied electronically, the lower part of the lens carries a softer fixed correction. There is less peripheral blur and less swim effect, so the visual habits used for walking, stairs and driving stay intact during adaptation.

Where can optical retailers and distributors source Morrow eyewear?

Morrow works through a network of certified optical partners. Use the Where to Buy directory to locate an authorised practice, or contact info@www.jamarai.com for distribution and partnership information.

Active Liquid-Crystal Switching

Precision Ophthalmic Engineering Tailored for Swiss Optical Standards

The Swiss eyewear market stands as one of the most demanding worldwide, characterized by strict medical device standards, high consumer expectations for visual acuity, and extreme environmental factors such as high-altitude alpine UV glare. To successfully supply optical laboratories in Zurich, Geneva, Basel, and Lugano, a manufacturing partner must deliver optical lenses with minimal chromatic aberration, pristine surface curvature control, and durable thin-film coatings.

As a leading Chinese optical lens manufacturer and OEM factory, we bridge high-capacity automated production with Swiss-level precision engineering. By incorporating advanced German free-form digital surfacing machines (Satisloh) and Leybold vacuum nano-coating chambers, our optical products consistently exceed standard ISO 8980 tolerances for focal power accuracy, prismatic distortion, and impact resistance.

Information Gain Insights for Swiss Distributors: European presbyopic wearers are shifting rapidly toward wide-corridor digital progressive lenses and smart active-focus solutions. Achieving lower peripheral swim effect requires custom-surfaced back-aspheric designs paired with MR-series high-index substrates.

Our OEM export program provides Swiss opticians with single vision, finished bifocal, traditional progressive, and futuristic electro-active smart lenses—all supplied with comprehensive CE certification, full traceability, and custom white-label packaging.

High-Performance Optical Application Scenarios in Switzerland

Customizing optical lens substrates and coating technologies to meet the distinct lifestyle, climate, and occupational demands of Swiss end-consumers.

Alpine UV420 & Photochromic Protection

High-altitude environments in the Swiss Alps (e.g., Zermatt, St. Moritz) expose eyes to intense UV rays and snow reflections. Our 1.60 and 1.67 SHMC photochromic lenses automatically adjust shade intensity while filtering harmful blue-violet light up to 420nm, preserving retinal health during outdoor mountain activities.

Swiss Financial Hub Ergonomic Workstation Lenses

Tailored for banking professionals in Zurich and international organization specialists in Geneva. Our 1.56 & 1.60 progressive and occupational lenses expand the intermediate visual field by up to 3×, reducing neck fatigue, digital eye strain, and visual swim effects across multi-monitor setups.

Active Electro-Progressive Smart Lens OEM

Leveraging state-of-the-art liquid-crystal cell lamination inspired by Morrow Eyewear's smart optics, our factory produces active tunable-focus substrates. Wearers switch near-reading addition (+1.00 to +3.00D) electronically in under 0.1 seconds, eliminating soft fixed lower power distortions entirely.

Advanced Liquid Crystal Optics and Corridor Width Visualization

Material Science & Surface Geometry: CR-39 to 1.74 High Index

Achieving superior optical clarity requires balancing refractive index ($n_d$) with Abbe number ($V_d$). Lower refractive materials like CR-39 offer an exceptional Abbe value of 58, ensuring virtually zero chromatic dispersion. However, for higher prescriptions, Swiss opticians demand ultra-thin profiles crafted from Mitsui MR-8 (1.60), MR-7 (1.67), and MR-174 (1.74) monomer resins.

Key Engineering Metric: Our cleanroom coating lines apply an 11-layer Super Hydrophobic Multi-Coating (SHMC), boosting light transmittance to 99.2%, reducing surface reflections to under 0.5%, and providing a surface contact angle > 110° for dust and water repellency.

Whether you require standard semi-finished optical blanks for local lab surfacing or fully finished free-form progressive lenses with customized corridor lengths (12mm, 14mm, or 17mm), our factory guarantee strict spherical and cylinder power consistency across every batch.

Procurement Guide

Frequently Asked Questions by Swiss Optical Importers

Technical and logistical answers to help optical laboratory owners and buyers streamline sourcing from China.

What certifications and regulatory approvals accompany your optical lens shipments to Switzerland?

All optical lenses exported from our China manufacturing facility to Switzerland are manufactured under ISO 13485:2016 Medical Devices Quality Management System. They fully comply with the European Medical Device Regulation (EU MDR 2017/745) and bear CE marking. We provide full Declaration of Conformity (DoC) documents, material safety datasheets (MSDS), and optical transmission test reports required by Swiss customs (EZV) and Swissmedic.

How do your high-index photochromic lenses perform under Alpine high-altitude UV conditions?

Our 1.60 and 1.67 SHMC photochromic optical lenses utilize spin-coated matrix photochromic dyes imported from Japan. In high-altitude areas like the Swiss Alps, where ambient temperature is lower and UV radiation is significantly stronger, our lenses rapidly darken to 85% light absorption within 30 seconds without suffering from cold-temperature kinetic lockup. Additionally, they incorporate UV420 cutoff technology to absorb intense blue-violet scatter radiation.

What optical power tolerances and surface curvature standards do you guarantee for OEM orders?

We adhere strictly to international ISO 8980-1 (Single Vision & Progressive) and ISO 8980-2 standards. Spherical power tolerances are held within ±0.06D for diopters under 6.00D, and astigmatic axis orientation is maintained within ±1 degree. Free-form progressive corridor geometries are 100% inspected using automated Nidek and Zeiss digital lensometers before vacuum coating.

What is the typical shipping lead time and import duty structure for deliveries to Zurich or Geneva?

Standard semi-finished optical blanks and stock single vision lenses ship within 7 to 10 working days. Custom free-form RX progressive orders typically require 4 to 6 working days in production. Air freight shipments to Zurich Airport (ZRH) or Geneva Airport (GVA) via DHL Express or FedEx arrive in 3 to 5 business days. Under Swiss customs tariffs, optical lenses falling under HS Code 9001.10 / 9001.50 can enter under duty-free or minimal preferential tariffs when supported by our preferential Certificate of Origin.

Can your factory produce liquid-crystal electro-progressive lens substrates for smart eyewear brands?

Yes. In addition to traditional resin and glass optics, our high-tech cleanroom facility features specialized liquid-crystal cell lamination lines. We partner with innovative smart eyewear developers to manufacture electro-active liquid-crystal lenses capable of instantaneous electronic focal tuning (+1.00D to +3.00D boost) via low-voltage activation, providing a seamless optical foundation for smart presbyopia eyewear.

How do you ensure zero-defect coating adhesion (hydrophobic & anti-scratch) during long-term wear?

Every coating batch undergoes rigorous environmental testing, including 24-hour saltwater immersion tests, boiling water adhesion tests (cross-hatch tape pull tests), and automated Bayer abrasion resistance testing. Our multi-layer zircanium oxide (ZrO2) and silicon dioxide (SiO2) AR stacks achieve a surface hardness rating of 5H to 6H, ensuring long-term scratch protection and easy-to-clean hydrophobic performance.
