Polarized Sport Sunglasses for Men and Women

Polarized Lenses Reduce Glare

Polarized KastKing sunglasses significantly reduce glare from reflective surfaces, enhancing your vision and comfort. Our 1.0mm lenses are comparable in thickness to higher-priced sports eyewear, delivering superior light filtering capabilities.

Impact-Resistant TAC Lenses

Our impact-resistant TAC (Triacetate) lenses are rigorously tested to pass a double decentering test, ensuring no optical distortion. This prevents eye strain and headaches, making our sunglasses ideal for outdoor activities.

Premium Grilamid Frames

Crafted from Grilamid, a material commonly used in military and medical applications, our frames are lightweight, flexible, and UV resistant. Grilamid's strength and durability ensure your glasses retain their shape and compensate for the lack of distortion.

Anti-Slip Nose and Temple Pads

Our glasses come with anti-slip nose and temple pads, ensuring a comfortable and secure fit. The Grilamid material's shape integrity and impact resistance provide a snug and stable fit, preventing slippage.

100% UV Protection

KastKing sunglasses block 100% of harmful UVA and UVB rays, adhering to and often exceeding U.S. ANSI standards. Ideal for those concerned about long-term eye health.

Base Lens Colors and UV Protection

Smoke Lenses

Perfect for bright sunlight, smoke lenses offer the most realistic color reproduction and work well in medium light and partial shade.

Brown Lenses

Ideal for partly cloudy to sunny conditions, brown lenses increase contrast and depth perception, enhancing visibility in changing light conditions.

Copper Lenses

Best suited for moderate to low light, copper lenses provide excellent contrast and depth perception, ideal for outdoor activities in various lighting conditions.

Protect Your Sunglasses

KastKing comes with a molded custom hard case for storage and a Prym1 Camo microfiber pouch for cleaning and storing. Clean your lenses with a clean microfiber cloth or lint-free cloths and fresh warm water. Avoid contact with saltwater and never dry with paper towels to prevent damage.
