Polarized lenses reduce glare - Impact resistant TAC lenses protect your eyes from flying objects - Lightweight, durable, and comfortable Grilamid frames – Anti-slip nose and temple pads - Block 100% of the harmful UVA and UVB rays – Full wrap design for maximum protection
1.0mm polarized lenses are comparable to the thickness you would find on much higher priced sports eyewear. KastKing TAC (Triacetate) lenses pass a double decentering test to ensure there is no optical distortion which can cause eye strain and headaches. KastKing Polarized sunglasses help reduce glare caused by reflected light to improve vision and comfort.
Made from the same Grilamid material commonly used in military and medical applications, KastKing sunglass frames are lightweight, extremely flexible, and heat and UV resistant. Grilamid frames are well known for their astounding strength, lightweight, comfort, shape integrity, and impact resistance. This virtually indestructible ultra-lightweight and malleable material translates to an amazingly comfortable fit and the tacky nose pads prevent slipping.
Smoke lenses are ideal for bright sunlight with the most realistic color reproduction and work well in medium light and partial shade. Brown lenses increase contrast and depth perception, ideal for partly cloudy to sunny conditions. Copper lenses were best suited for moderate to low light. KastKing sunglasses block 100% of the harmful UVA and UVB rays and meet or exceed all U.S. ANSI standards.
KastKing includes a molded custom hard case for storage and a custom Prym1 Camo microfiber pouch which can be used for cleaning as well as storing your sunglasses. To avoid lens scratches and lens coating damage, clean your lenses with a clean microfiber cloth or lint free cloths and fresh warm water. Never dip them in saltwater or dry with a paper towel.
