In practice: it takes the edge off screen light without noticeably changing how colors look, so it's wearable through a full working day, on video calls, and for color-critical work where a tint isn't an option.\u003c\/p\u003e\n\u003cp\u003eA light filter rather than a treatment for anything — the research on blue-light filtering and eye strain is mixed at best, and we set out what it shows on our \u003ca href=\"https:\/\/sleepzm.com\/pages\/science\"\u003escience page\u003c\/a\u003e.
