● Blue light and our daily life: Blue blocking lenses are designed to filter out high-energy blue light in visible spectrum. IDEAL lenses are specially designed to filter out some of the highest energy wavelengths in visible spectrum (400-440 nm) with the help of clear substrate and anti-reflection coating. The bottomless clear lenses are almost transparent, which means that the color temperature won’t be significantly affected when viewing objects-this is vital to the users who are engaged in work such as graphic design and need to see true colors. There is no need to block out 100% of the blue wavelengths in daily life, because some exposure to blue light at appropriate times of the day can help people maintain their natural circadian rhythm. Our dual-effect blue blocking lenses filter out enough blue light to make people's eyes feel more relaxed, while allowing beneficial blue light to pass through for a healthy sleep-wake cycle.
● Photochromic lenses can be worn throughout the day on the daily basis and used just like normal eyeglasses. These lenses are beneficial to all the people, especially those who constantly move from outdoors to indoors. They are highly recommended for children as they tend to spend much time playing outdoors, and can therefore protect their eyes from sun rays.
