Blue Light, or High Energy Visible (HEV) light, is a part of the visible light spectrum with high energy. Naturally emitted by the sun, it plays a crucial role in regulating our sleep-wake cycle, known as the circadian rhythm. Natural blue light is beneficial for alertness, memory, cognitive function, and mood enhancement. At sunset, the reduction in blue light triggers melatonin production, aiding sleep.

However, with technological advancement, exposure to artificial blue light from devices like TVs, smartphones, computers, and certain types of lighting has increased. This can disrupt our natural sleep patterns, cause eyestrain, fatigue, and headaches.

To combat blue light fatigue, reducing screen time and taking breaks can help, although it's not always practical. Blue light filters for screens and blue light blocking glasses are effective solutions.
