Effectiveness of Blue Light Filtering Glasses
Prolonged exposure to blue light from screens can have several adverse health effects, including visual discomfort, disrupted sleep patterns, and potential long-term health risks. Blue light filtering glasses may offer some relief from these symptoms, particularly for those experiencing Computer Vision Syndrome. However, further research is needed to fully understand the long-term impacts of blue light on ocular health and overall well-being. Reducing screen time, especially before bedtime, and using protective measures like blue light filters can help mitigate these negative effects.
