The Performance You Can Expect

OUTSTANDING LENSES

1.0mm polarized lenses that rival those found in top-tier sports eyewear, offering clear vision even on bright, sunny days. KastKing TAC (Triacetate) lenses have passed a double decentering test, ensuring no optical distortion that can cause eye strain and headaches. These KastKing polarized reading sunglasses minimize glare from reflected light, enhancing both your vision and comfort.

SUPERIOR FRAMES

Our frames are made from Grilamid, the same material used by the military and in medical applications. These frames are lightweight, flexible, and incredibly durable. Grilamid frames are known for their strength, lightweight comfort, shape integrity, and impact resistance. The ultra-lightweight and malleable nature of Grilamid ensures a very comfortable fit, making these sunglasses suitable for any outdoor or indoor activity.

BASE LENS COLOR AND UV PROTECTION

• Smoke Lenses: Ideal for bright sunlight, they provide the most realistic color reproduction and are great for medium light and partial shade conditions.
• Brown Lenses: Increase contrast and depth perception, making them perfect for partly cloudy to sunny conditions.
• Copper Lenses: Offer excellent contrast and depth perception, ideal for moderate to low light.

These lenses block 100% of harmful UVA and UVB rays, meeting or exceeding all U.S. ANSI standards.

PROTECT YOUR EYEWEAR

KastKing includes a molded custom hard case for storage and a custom Prym1 Camo microfiber pouch for both cleaning and storing your sunglasses. To keep your lenses in top condition, always use a clean microfiber cloth or lint-free cloth and clean with fresh, warm water. Avoid dipping the sunglasses in saltwater and never dry them with a paper towel.
