Metal Square Frame UV400 Polarized Sunglasses

Key Features

Slim Square Metal Frame

The slim metal frame creates a sharp square outline without adding unnecessary visual weight. Its narrow rims give the sunglasses a cleaner appearance than many thick-frame styles, while the metal structure helps the front retain its intended shape during normal handling.

The simple profile works with casual, street, travel, and business-casual styling. It is distinctive enough to be noticed but restrained enough for frequent daily wear.

1.1 TAC Polarized Lenses

These sunglasses are fitted with 1.1 TAC polarized lenses. The polarized function helps reduce reflected glare from outdoor surfaces such as roads, water, windows, and wet ground.

This makes the lenses a practical option for bright daytime environments. Lens color, polarization, and other requirements should be checked against the approved specification before production.

UV400 Sun Protection

The UV400 lenses help filter ultraviolet rays during ordinary exposure to sunlight. Together with the polarized function, they support product directions such as driving, walking, commuting, traveling, seaside use, and outdoor leisure.

Polarization and UV400 protection refer to different lens properties. The final lens configuration should therefore be clearly listed in the order specification and confirmed with the approved sample.

Adjustable Nose Pads

Clear adjustable nose pads make it possible to fine-tune how the frame rests around the bridge. Small adjustments can help improve frame height, lens position, and overall fit for different nose shapes.

The nose pads also maintain some distance between the lenses and the face. Their angle, position, and left-right consistency should be checked during assembly.

Decorative Metal Temple Detail

A flower-style metal detail is set near the hinge area of each temple. It gives the Square Frame Fashion Sunglasses a more recognizable side profile while keeping the overall design tidy.

During production, the decorative pieces should be checked for position, alignment, surface condition, and fixing consistency. Both sides should match the approved sample as closely as possible.

Lightweight Wearing Feel

At about 30g, the sunglasses provide a relatively light wearing feel for a full metal design. The 147mm temples extend naturally toward the ears, while the curved temple tips help keep the frame in position during everyday movement.

Comfort still depends on more than weight alone. Frame width, bridge fit, nose-pad position, temple curve, and lens balance all contribute to how the sunglasses feel when worn.

Factory Manufacturing Notes

Zhejiang Zhansheng Glasses Co., Ltd. has long-term manufacturing experience in metal sunglasses, including metal-frame shaping, rim adjustment, lens fitting, hinge assembly, polishing, surface treatment, and final inspection.

For model PS33269, the square lens profile requires careful left-right control. Both lenses should sit at a consistent height and angle, and the metal rims should follow the approved shape without visible distortion. Lens edges must correspond with the rim structure so that the finished frame maintains its clean geometric appearance.

The hinge area is checked for smooth movement and matching opening angles. Temple alignment is also important because a difference between the left and right sides can affect how the sunglasses sit on the face. The flower-style temple details should remain secure, evenly positioned, and visually consistent.

Other production checkpoints include nose-pad angle, frame width, lens color, polarized-lens condition, plating quality, surface marks, and wearing balance. These details are reviewed against the approved sample before larger production quantities are released.

The Square Metal Frame Sunglasses can be developed with different frame colors, lens tones, logo placements, and packaging formats. Sample confirmation may include frame dimensions, gradient depth, temple printing, logo size, nose-pad fit, decorative alignment, surface finish, hinge operation, and overall appearance.

Customization Options

These customization options allow the Metal Square Frame UV400 Polarized Sunglasses to be adjusted for different brands and market directions without changing the main structure of model PS33269.

Frame color can be coordinated with the selected gradient lens, while the logo may be placed on the lens, temple, inner temple, or packaging according to the brand design. Packaging can also be prepared for retail, e-commerce, wholesale, or promotional programs.

All customized details—including color references, lens specifications, logo artwork, surface treatment, and packing requirements—should be confirmed through the final approved sample before volume production.
