Dual-zone lighting: The light on your child's desk and the surrounding area are both equally important for homework.

Many parents focus only on whether a desk lamp is bright enough, overlooking the entire lighting environment around their child's eyes. Eye care research introduces the concept of "dual-zone light control": desktop illumination should exceed 1000 Lux to stimulate retinal dopamine secretion, while ambient light around the eyes must remain within 450-600 Lux to avoid being too dim or too bright. Understanding this principle helps you create a truly scientific reading and writing light environment for your child.

Understanding this mechanism helps you interpret treatment data rationally while maintaining consistent daily eye care habits.
