NeoContrast Day and Night Shades (UV-Darkening), Photochromic Lenses, Blocks 99.99% of UV Rays, Perfect for Night Driving, Made in Sabae, Fukui

The much talked about NeoContrast sunglasses for day and night use now come in photochromic form! The well-known yellow light blocking technology creates a dramatic effect! (76% visible light transmittance = suitable for nighttime use ⇒ darkens to at least 15% under UV light ⇒ UV transmittance of less than 0.01%) The lens yellows with age. This yellowing reduces the sensitivity to blue light, which is necessary for vividness, and increases sensitivity to dazzling yellow light. Symptoms such as blurred vision, blurred outlines, dim vision, and a lack of clarity in the scenery are often caused by yellowing. NeoContrast lenses focus on filtering out only the most dazzling yellow light (585nm)! Even though they're not a dark lens color, they significantly reduce glare and ensure a bright, clear field of vision. Furthermore, the photochromic lenses darken under UV rays, further reducing glare! They can be worn in tunnels while driving, or during the day, evening, night, sunny days, or rainy days, so you can wear them for everyday use without needing to change lenses! They're also definitely recommended for all outdoor activities (sports, fishing, hiking, travel, sightseeing, etc.). The frame is made of flexible resin for an excellent fit! Two-in-one sunglasses. Made in Sabae, Fukui Prefecture, with neo-contrast photochromic lenses that darken under UV light. Hopnic Laboratory, a pioneer in Japanese lenses, confidently recommends these sunglasses for both day and night wear. *The lens color will not change in places with little (or no) UV rays. Therefore, if you are driving a car with a UV-blocking windshield or wearing the glasses in places with little UV rays, the lens color will not darken and some glare will remain.
