True Dark Classic Box Set (Twilight + Daywalker)
With the Daywalker Elite, filter some, but not all, blue spectrum so you can keep your body in-tune with what’s happening outside as the sunlight begins to go down, even while you’re still hard at work. It also can help reduce eye strain for those who are in front of a computer all day long.
The Twilight glasses go beyond a simple blue light filter and block the entire spectrum of light disrupting your sleep and performance. Used at night-time and for airline travel, your circadian rhythm has never been so in touch.
