Ever since Costa Sunglasses, Inc. introduced the Costa Del Mar 580 pair of sunglasses to the world, in 2000, they have never looked back! Numerous customers continue to vouch for its fine quality and excellent protection against the harsh glare of the sun. Logically, every brand of sunglasses is designed to keep the eyes concealed from the negative effect of the sun’s UV rays; what is so special about this one?
Well, it might be necessary to delve into a Science lesson, if you are to understand why this eyewear is so popular across the globe. During your school days, you must have heard your teacher mention the light spectrum. What we view as ‘white’ light is actually a combination of seven colors. These colors include violet, indigo, blue, green, yellow, orange and red. Violet marks the beginning of the light spectrum at a wavelength of 400 nanometers, while red marks the end of it at a wavelength of 700 nanometers. Your naked eyes cannot adjust to ultraviolet (below 400 nanometers) rays, or infrared (beyond 700 nanometers) rays. Therefore, when you stay outdoors for long periods, you need protective gear for your eyes.
While you are grateful for the scientific reasoning behind the wearing of sunglasses, you are still unable to comprehend why you need to purchase Costa Del Mar 580 only. The answer is simple; it helps to reduce yellow light, while enhancing the other colors. You might have noticed that when you use violet, indigo, blue, green, orange and red highlighters on white paper, they are easy to view, as well as withstand. Try the same with yellow color; your eyes will face some difficulty in deciphering anything clearly. In fact, they may even begin to feel strained and exhausted after some time. You will face a similar experience if you stay in a room lighted with yellow bulbs for a lengthy period. Thus, you may conclude that yellow is extremely difficult for the eyes to process.
You need have no apprehensions about quality, for the polarized lenses are engineered solely at Florida, even if the frames are designed at other geographical locations and sent over to the U.S. The lenses used to be made of glass earlier; today, they are created from polycarbonate material. Costa Del Mar 580 sunglasses are lightweight; durable; scratch-resistant; provide wonderful optical clarity; and protect against UVA, UVB and UVC rays. The lenses are available in different colors. For instance, blue with a gray base, green with an amber base, and silver lenses are excellent for the open waters when you go fishing or sailing. Gray-colored lenses are great for land and water sports. Copper-colored lenses are suitable for everyday activities, including driving.
