As the nights draw in, it's a relief to find a company offering artificial daylight. Clearvision's Virtual Daylight system mimics natural daylight, providing - the company claims - a natural, low-glare, flicker-free environment. Clearvision says the system provides an antidote to stress, fatigue, and headaches which could be attributed to poor lighting in classrooms. Good news for students and teachers alike.
