Understanding Blue Light and Its Effects
What is Blue Light?
Blue light is part of the visible light spectrum with a wavelength between 400-500 nanometers. It is emitted by natural sources like the sun and artificial sources such as digital screens, LED lights, and fluorescent lighting.
Negative Impacts of Blue Light Exposure:
Eye Strain and Discomfort: Prolonged exposure to blue light can lead to digital eye strain, characterized by dry eyes, headaches, and blurred vision.
Disrupted Sleep Patterns: Blue light interferes with the production of melatonin, a hormone that regulates sleep. Exposure to blue light in the evening can disrupt sleep patterns and reduce sleep quality.
Potential Long-Term Damage: Continuous exposure to blue light may increase the risk of age-related macular degeneration, a leading cause of vision loss in older adults.
Science Behind Blue Light Filtering Technology:
Blue light filtering technology works by blocking or filtering out the high-energy blue light emitted from screens. This helps to reduce eye strain and improve overall eye health. Different colors of lenses offer varying levels of protection and benefits.
