Who really needs a blue-light filter?

Blue light is a natural part of sunlight; screens simply hold a narrower band of it in front of the eye for longer.

Discomfort is often less about colour than about reduced blinking, near work and dry air. Our first advice is still blink breaks, moisture and good lighting.

That said, people who work late, who are migraine-prone, or who describe reflection fatigue may find a filter a measured comfort layer.

At Kubat Optik we treat blue-light coating as a lens option discussed against your habits — not as a fashion add-on.
