When talking about Costa Del Mar sunglasses a regular question we get is: “What is the difference between the 400 and the 580?” So here it is: Costa offers two lens quality available. The Costa 400 eliminates glare at the 400 nanometer mark. This allows for clearer vision and reduces strain on eyes.
The Costa 580 is the premium lens collection. This lens eliminates glare at the 580 nanometer mark. Specifically, it significantly reduces the amount of yellow light that penetrates the lens; yellow light is the hardest light for the eye to process. This nearly completely eliminates glare, allowing enhanced color saturation and definition. The 580 price has been adjusted significantly so now it wont be a huge difference in price to get the 580 instead since you will be getting better quality for your buck.
