The popular NeoContrast sunglasses, suitable for both day and night wear, now come in a photochromic version! Experience dramatically improved visibility thanks to its yellow light-blocking technology! (Visible light transmittance 75% = suitable for nighttime use ⇒ darkens to a minimum of 20% under UV light; UV transmittance less than 0.01%) The new standard for computer glasses is not blue light blocking, but yellow light blocking. The reason is the "yellowing" of the lens of the eye. This yellowing reduces the sensitivity to blue light, which is necessary for vivid vision. Therefore, after the age of 40, blue light becomes the light necessary for vision. Symptoms such as "brightness and blurred vision," "blurred outlines," "dim vision," and "scenery not looking as beautiful" are often due to the yellowing of the lens of the eye. NeoContrast lenses selectively cut only the yellow light (585nm) that causes the most glare! Despite being a light color, they dramatically reduce glare and ensure clear vision. They alleviate eye strain and provide vivid vision when using smartphones and computers. They also block 99% of UV rays outdoors, making them an essential item for comfortable driving. No need to change glasses in tunnels or on rainy days. With their outstanding fashion sense, they are also recommended for everyday use! An absolute must-have product for smartphones, PCs, outdoor activities, travel, sightseeing, and more. Why does it alleviate eye strain and improve vision? ...Because it cuts out yellow light. To see things clearly, not only so-called "visual acuity" but also "contrast sensitivity," which allows you to distinguish between shadows and differences in color, is important. NeoContrast is a new type of eyeglass lens (patented in Japan and the US) that selectively cuts out only the yellow wavelengths of light that enter the eye, which are the cause of poor vision. This makes objects appear clearer, sharper, and more vivid. How is it different from sunglasses? …It reduces glare without darkening the field of view. Generally, sunglasses reduce glare by uniformly cutting out visible light of various wavelengths, but this causes a loss of vibrancy and contrast in the field of view. That's why it becomes difficult to see. NeoContrast reduces glare without darkening the field of view, and further improves contrast, creating a comfortable field of view. We are absolutely confident in this latest model of smartphone and PC glasses. Please try it! These sunglasses feature photochromic lenses from a world-leading manufacturer of eyeglass lenses in Sabae City, Fukui Prefecture, a renowned center for eyeglass production. They reduce glare from wet roads and eliminate shadows on windshields. Outdoors, the photochromic function effectively reduces strong glare. The lenses automatically change color, becoming darker in bright conditions and lighter in dark conditions. This ensures that you can maintain the appropriate brightness of your vision at all times.
