Brand Introduction
Yuhuan Longsen Optical Co., Ltd. has been deeply rooted in the eyewear industry for 14 years. Our founder transitioned from a technical specialist to a corporate executive, personally overseeing every stage of the production process. We are not merely manufacturers; we are technical experts who truly understand eyewear.
Our Superlite Titanium Rimless Glasses embody our core business philosophy: crafting quality through meticulous artistry.
For many years, we have served as an OEM/ODM partner for renowned brands such as Hailun, which demonstrates that our craftsmanship meets the rigorous standards of major international labels.
We currently hold 12 product patents, providing our distributors and agents with a distinct competitive advantage in the market.
Key Features

A Feather-Light Wearing Experience
The defining characteristic of these glasses is their extreme lightness. The entire frame weighs only 8 grams-lighter than a single sheet of A4 paper.
Wearers can keep them on all day without experiencing fatigue, and the bridge of the nose and ears remain free from pressure marks or indentations.
The frames are made from aerospace-grade titanium alloy, which is not only incredibly lightweight but also exceptionally durable. The material offers excellent corrosion resistance, preventing sweat from damaging the frame surface.
Customers with sensitive skin can wear them with complete peace of mind, as all materials have passed EU REACH environmental compliance tests. In addition, all metal components are nickel-free, ensuring they do not trigger allergic reactions.
Craftsmanship Details
Precision Processing Through 30+ Steps
Each pair of Superlite Titanium Rimless Glasses undergoes a meticulous production process involving more than 30 steps.
We use precision engraving machinery for high-accuracy cutting, followed by expert hand polishing performed by skilled technicians.
The frame surface is treated with a special protective coating that keeps the colors vibrant over time and resists fading and discoloration.
We use medical-grade screws to secure the lenses. Once tightened, these screws remain firmly in place and resist loosening, ensuring long-term stability.
The tips of the temples are fitted with soft silicone sleeves, allowing the angle to be adjusted to fit the unique contours of each customer's ears.
This design ensures that the glasses remain securely in place-even during vigorous physical activity-without slipping.
