Emitted by devices such as smartphones, tablets, computers and televisions, blue light has the ability to penetrate deeper into our eyes than other forms of visible light.<\/p>\n<h6><strong>Consequences of exposure to this type of light<\/strong><\/h6>\n<p>This type of prolonged exposure can contribute to eye fatigue, headaches and even sleep disturbances, as it interferes with the production of melatonin, the hormone responsible for regulating sleep.<\/p>\n<h6><strong>Long-term risks<\/strong><\/h6>\n<p>In addition to these more immediate effects, studies suggest that prolonged exposure to blue light can increase the risk of macular degeneration, one of the main causes of vision loss in older age. Given the inevitability of our interaction with digital technologies, it is essential to adopt protective measures.<\/p>\n<h6><strong>Lenses with Blue Light Filters<\/strong><\/h6>\n<p>The use of lenses with blue light filters is an effective solution. These lenses were developed to filter out part of the blue light (read \"<em>Why you shouldn't block out blue light completely<\/em>\") and minimise the risks associated with their exposure. As well as helping to reduce eye fatigue, they improve visual comfort and can contribute to more restful sleep by enabling better regulation of melatonin.<\/p>\n<h6><strong>Conclusion<\/strong><\/h6>\n<p>Investing in lenses with blue light protection is an investment in eye health and general well-being. It's a prudent choice for those who spend many hours in front of screens, whether for work or leisure, protecting their eyes today and helping to prevent vision problems in the future.<\/p>\n<p><strong><em>Why shouldn't blue light be completely blocked out?<\/em><\/strong><\/p>\n<h6><strong><em>Circadian Rhythm Regulation<\/em><\/strong><\/h6>\n<p><em>Blue light, especially in the 460-480 nm range, is essential for regulating the circadian rhythm (our biological cycle of sleep and wakefulness). Exposure to this light during the day stimulates cortisol production and suppresses melatonin, helping to keep us awake and alert. If we completely block out this light during the day, there can be negative impacts on the quality of sleep and the general functioning of the body.<\/em><\/p>\n<h6><strong><em>Colour Perception and Visual Quality<\/em><\/strong><\/h6>\n<p><em>The human eye is naturally adapted to process a full spectrum of light, and blue light contributes to the perception of colours and contrast. If we completely eliminate this component, we can create a feeling of \"washed out\" vision with less definition, which can be uncomfortable, especially for tasks that require fine perception of details.<\/em><\/p>\n<h6><strong><em>Security and night vision<\/em><\/strong><\/h6>\n<p><em>Blue light contributes to vision in low-light environments, as it participates in the eye's process of adapting to the dark. If we completely eliminate this light, we can jeopardise our ability to adapt to night-time environments, which can be particularly dangerous for those who drive at night.<\/em><\/p>","protected":false},"excerpt":{"rendered":"<p>Num mundo cada vez mais digital, onde os ecr\u00e3s fazem parte integrante do nosso dia-a-dia, \u00e9 fundamental estar atento aos impactos da exposi\u00e7\u00e3o constante \u00e0 luz azul.
