■ This product is a functional pair of glasses developed based on the "Night Navigator" series of sunglasses for nighttime driving, which has been selling for over 20 years (over 60,000 units sold in total). It is suitable for both day and night use and all weather conditions. ■ The lenses used in these new functional glasses have a special function that cuts out over 99% of strong blue light (450nm) that can pierce the eyes, which cannot be cut out by ordinary yellow-tinted lenses. In addition, these functional glasses are an "all-weather type," providing not only protection against the glare of LED headlights of oncoming cars when driving at night, but also "reduced glare and a bright, clear, and high-contrast view" in bad weather conditions such as rain, snow, and fog, or on bright sunny days.
■ The frame is made of polycarbonate, a lightweight, elastic, and impact-resistant material. As a result, the over-the-glasses sunglasses weigh only about 38g (including lenses), making them comfortable even for extended wear. They can also be worn over regular glasses, effectively functioning as prescription sunglasses when used with prescription lenses.
■ These glasses feature functional lenses that cut out over 99% of "glaring blue light (strong blue light around 450nm)," which causes flickering and glare in your vision. Furthermore, the lenses have 14 layers of anti-reflective coating (7 on the front and 7 on the back). This significantly reduces "unwanted light" reaching your eyes from various angles, resulting in a clear and sharp field of vision.
■ These functional overglasses not only reduce the glare from LED headlights of oncoming vehicles when driving at night, but also brighten visibility and enhance contrast in adverse weather conditions (rain, snow, wind, fog, mist, etc.). Furthermore, they significantly cut out ultraviolet rays and blue light (280nm-450nm), which are said to be causes of glare and flickering, so they can be used even in bright sunlight during the day. Please use them as sunglasses that reduce glare and create a clear, high-contrast view in all weather conditions, day and night.
