What to Look for in Costa Sunglasses
Since 1983, Costa Del Mar sunglasses have been the preferred eyewear to enjoy life out on the water. With eco-friendly, durable frame materials and crystal-clear optics, Costa commits themselves to providing the best visual experience to enjoy nature’s beauty while protecting the planet. For everything you need to know about Costa Del Mar, visit our Costa Sunglasses Buyer’s Guide. For a quick recap of Costa’s proprietary frame and lens materials, continue reading below.
Frame Technology
As part of their Kick Plastic Initiative to reduce their carbon footprint and protect Earth’s waters, Costa uses a bio-based resin to create their popular TR90 nylon frames. Built to last while keeping you comfortable, this eco-friendly material provides ultra-lightweight wear and feel-good attitude. It also is anti-corrosive and saltwater-safe, so you can enjoy your Costas out on the water for years to come.
As for performance, Costa uses Hydrolite™ rubber to create a comfortable and secure grip. Reacting to moisture, Hydrolite™ gets tackier when wet, so you don’t have to worry about frame slippage or adjustments.
Lens Technology
Costa 580 lens technology is the next level in color and contrast enhancement. With a 99.9% polarization efficiency, Costa 580 has the best glare reduction on the market. It also protects against UVA/UVB/UVC light and harmful blue light for long days under the sun. Available in 580G (glass) and 580P (polycarbonate), there are 7 colors designed to enhance your specific environment and activity.
