KARUSON Precision Round Sunglasses — Professional Grade

KARUSON Precision Round Sunglasses are engineered for professional-grade performance with attention to materials, fit, and optical quality. Built in our vertically integrated factories in Dongguan and Guangzhou, these round sunglasses combine precision-milled frames (including lightweight TR90 and metal options), high-clarity polarized and UV400 lens technologies, multi-layer coatings (anti-scratch, anti-reflective, hydrophobic), and precision logo engraving. Our 15+ years of eyewear manufacturing expertise, 300+ trend-setting designs, and rigorous quality-control processes ensure consistent tolerance, color matching, and long-term durability—so you get round sunglasses that look High Quality, protect your eyes, and withstand everyday use.

Yes. KARUSON round sunglasses are offered in multiple sizes and adjustable fits to suit various face shapes—from narrow to wider faces—thanks to frame geometry options and flexible materials like TR90. Many models are compatible with prescription lenses; our engineering team can adapt frame thickness and lens blanks to accommodate single-vision, progressive, or Rx sunglasses. To ensure the best fit, measure your existing frame’s lens width, bridge, and temple length or request a sample for fit testing. For prescription customization, work with your optician and contact our team to confirm compatibility.

As a global OEM/ODM supplier, KARUSON provides end-to-end customization for round sunglasses: bespoke frame engineering (material, color, finish), custom lens technologies (polarized, gradient, mirror, anti-reflective), custom temple shapes, packaging design, and precision logo engraving. We support rapid prototyping, small-batch runs and scalable mass production through our two factory bases. MOQ and lead times are flexible depending on specification—please contact nicole@karusonco.com or visit https://www.karusonco.com to discuss your project and request a quote.

Proper care extends the life of your round sunglasses: clean lenses with a microfiber cloth and lens-safe cleaner or mild soapy water; avoid paper towels, clothing, or household chemicals that can scratch coatings; store sunglasses in a protective case when not in use; avoid leaving them in extreme heat for long periods. If your sunglasses have adjustable nose pads or screws, check them occasionally and tighten gently. KARUSON provides after-sales support and quality assurance—if you encounter manufacturing defects, contact nicole@karusonco.com for assistance and warranty information.
