In today's digital age, electronic devices have become a constant part of our lives, providing engaging visual experiences through tablets, smartphones, and computers. However, the blue light emitted by these devices may affect our eyesight.
Blue light, particularly wavelengths between 400 and 450 nanometers, can reach the retina. Studies suggest that high-energy blue light may impact the retinal pigment epithelial cells and photoreceptor cells, potentially affecting vision health over time.
Visual fatigue is another possible consequence of prolonged blue light exposure. Because blue light has a short wavelength, it focuses slightly in front of the retina rather than directly at its center. This can cause the eyes to remain tense, leading to visual fatigue. Extended visual fatigue may contribute to symptoms like nearsightedness, double vision, line misreading, and difficulty concentrating, potentially affecting learning and work performance.
Blue light can also impact sleep quality. It may suppress melatonin production, a hormone involved in regulating sleep and circadian rhythms. Using electronic devices before bedtime can therefore contribute to poorer sleep quality or occasional insomnia.
Some research links blue light to eye health issues like macular degeneration and cataracts, as it penetrates the lens and reaches the retina. However, it’s important to note that the risk from blue light exposure generally relates to intensity and duration. Indoor lighting, for instance, typically does not exceed 600 lux and is often encased in modes that do not emit high levels of blue light. Additionally, our eyes have natural protective mechanisms, including lens filtration and automatic adjustments to light intensity, which help mitigate blue light exposure in everyday settings.
A clinical trial conducted by Citruslabs Research Team in 2024 found that taking Eye Empower capsules supported vision health, including reducing sensitivity to blue light. Most participants were satisfied with the product and expressed a willingness to use it regularly as part of their vision care regimen. Eye Empower capsules are made from natural ingredients, blending traditional herbal formulations with modern biotechnological extraction methods. For example, the capsules include Virgate Wormwood Herb, which contains artemisinin, recognized for its antioxidant and anti-inflammatory properties. These characteristics may support nerve health, including within the visual system.
