What Is Blue Light?

Blue light is a high-energy visible (HEV) light with a short wavelength. It is naturally emitted by the sun, but also by artificial sources like digital screens, LED lights, and fluorescent bulbs.

How Blue Light Affects Your Eyes

1. Digital Eye Strain

Extended exposure to blue light from screens can cause eye discomfort, dryness, blurred vision, and headaches—a condition often called digital eye strain or computer vision syndrome.

2. Disruption of Sleep Patterns

Blue light interferes with the production of melatonin, the hormone responsible for regulating sleep. Using screens before bedtime can disrupt your natural sleep-wake cycle, leading to poor sleep quality.

3. Potential Retinal Damage

Some studies suggest that prolonged blue light exposure might contribute to retinal damage over time, potentially increasing the risk of age-related macular degeneration (AMD). However, research is ongoing.
