Blue light's impact extends beyond temporary discomfort, potentially affecting our long-term eye health and overall well-being.
The Nature of Blue Light: Sources and Composition
Blue light is part of the visible light spectrum that reaches our eyes from various sources, including the sun, screens and LED lighting. It is composed of shorter wavelengths, which means it carries more energy than other colours we can see.
How Does Blue Light Affect Vision and Health?
Blue light affects vision and health by potentially causing digital eye strain and disrupting sleep. Due to its high energy, it can fatigue the eyes after prolonged exposure to screens. This is because it scatters more easily, causing a reduction in contrast and contributing to the effort our eye muscles must make to maintain focus.
Furthermore, blue light influences our health by affecting our internal clock, or circadian rhythm, which regulates sleep. Exposure to blue light, especially at night, can trick our brains into thinking it's still daytime, leading to difficulties in falling asleep and reduced sleep quality. Managing blue light exposure is essential for maintaining both ocular health and overall well-being.
The Mechanism Behind Blue Light Glasses
Blue light glasses work by filtering out the blue light before it reaches the retina. They have specialised coatings that block or absorb blue light emitted from screens and other artificial sources, aiming to reduce the potential harm to the eyes.
