KastKing Estero Polarized Bi-Focal Sport Reader Sunglasses for Men & Women

The KastKing bifocal sunglasses feature a range of key attributes. The lenses are polarized, reducing glare, and impact-resistant, made of polycarbonate. An oleophobic coating repels saltwater, oil, and chemicals, making the lenses easy to clean and maintain. The lightweight, durable, and comfortable Grilamid frames block 100% of harmful UVA and UVB rays. Reading powers of 1.5, 2.0, and 2.5 are available.

The oleophobic lens coating is impervious to dirt, dust, oils, and other particles, resulting in a surface that is easy to clean and keeps the lenses cleaner for longer compared to untreated lenses. The 1.8mm polarized polycarbonate lenses feature integrated magnifiers that are flush with the outer lens surface and strategically placed for optimal vision enhancement. The magnifier sunglasses offer built-in magnification powers of 1.5x, 2.0x, and 2.5x.

The KastKing frames are made of Grilamid, a material commonly used by the military and in medical applications. They are lightweight, extremely flexible, and heat and UV resistant. Tacky nose pads and temple pads help prevent slipping, while the angular wrap design offers full coverage, blocking light and increasing visibility, making the sunglasses ideal for various activities such as driving, biking, running, boating, fishing, and golfing.

The smoke lenses are well-suited for bright sunlight, providing the most realistic color reproduction and working well in medium light and partial shade. The brown lenses increase contrast and depth perception, making them ideal for partly cloudy to sunny conditions. All KastKing sunglasses block 100% of harmful UVA and UVB rays and meet or exceed all U.S. ANSI standards.

To protect your KastKing eyewear, the sunglasses come with 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 the lenses with a clean microfiber cloth or lint-free cloths and fresh warm water. Never dip them in saltwater or dry them with a paper towel.
