Oversized Square Sunglasses with Metal Frame and UV400 Protection

These oversized square sunglasses utilize a solid metal frame construction paired with polycarbonate lenses designed to block ultraviolet radiation up to 400 nanometers. The uniform 5.8-inch frame width covers the standard adult facial span, eliminating measurement guesswork and accommodating diverse face shapes without trial sizing.

Material Composition

Every structural component relies on metal alloy fabrication. The front rim and temple arms share identical metallurgy to maintain balance and reduce flex under daily use. Polycarbonate lenses replace glass substrates, delivering impact resistance that prevents cracking when the frames rest accidentally on hard surfaces or are packed in bags.

Ultraviolet Filtration Specs

UV400 lens treatment filters 99% to 100% of UVA and UVB wavelengths. This specification removes the uncertainty of basic tinted shades by guaranteeing full spectrum protection for retina safety during extended daylight exposure. Each order delivers one complete pair aligned and ready for immediate wear.

Core Technical Details

• Frame geometry: Oversized square profile measuring 5.8 inches across the front
• Lens substance: Polycarbonate optics with integrated UV400 coating
• Structural build: Metal frame housing and matching metal temple arms
• Package quantity: 1 pair

Buyers frequently ask about long-term hinge retention and lens clarity. The rigid metal chassis preserves tension at the barrel joints through repeated opening cycles, while the polycarbonate material resists yellowing and abrasion better than cheaper plastic coatings. Imported assembly follows standard optical alignment protocols to ensure centered vision and comfortable temple pressure throughout routine outdoor activities.
