Beyond Polarized:
Costa 580 lenses were designed by in-house light spectrum experts to enhance colors because standard sunglass lenses fell short. The lens’ multipatented technology manages light by:
Absorbing Harmful High-Energy Blue Light (HEV):
Cuts haze and blur for greater clarity
In addition to 100% protection from UV light, 580 technology also absorbs HEV light known to cause macular degeneration, pterygium, cataracts and other eye diseases
Enhancing Reds, Greens, and Blues:
Blocking harsh yellow light at 580 nm on the visible light spectrum boosts the amounts of red, greens and blues naturally, enhancing colors and contrast
Filtering Out Harsh Yellow:
For enhanced color, sharper contrast and higher definition
Lens Technology:
Light conditions are constantly changing. To get the most out of Costa lenses, it's important to choose the right color. Costa Del Mar offers seven lens colors that range from low-light like dawn to extremely bright light with blinding glare.

Frame Qualities:
Costa offers frames to meet everyone's needs. Customers can choose a frame based on color, hypoallergenic materials, durability, lightness, cost and uniqueness. Each frame offers its own performance advantages and style features for eyewear that fits every occasion.
Co-Injected Nylon Frames:
The nylon frames are tough and durable, with more color options manufactured using the environmentally friendly bio-resin process. TR-90 nylon is a premier material for sports and performance frames as it is resistant to heat and cold. Though it is flexible, it is still durable. Nylon is easily molded into wraparound and other shapes.
Frame Materials:
Tri- Lateral Fusion
Costa is the industry leader in this manufacturing process.
Original bilateral and trilateral styles are created by bonding together two or three distinct colors into one frame.
Each layer is comprised of solid color bio-resin. The result is a highly durable frame with chip-proof color.
Costa offers multiple unique color combinations in both bilateral and trilateral styles.
Quality Hinges:
The corrosion-resistant, stainless steel flexible hinges keep their shape and fit perfectly.
They come in three types:
Integral
Optical spring
Five-barrel optical
