French experts have issued a stark warning about the dangers of LED lights, stating that they can cause permanent retinal damage and disrupt natural sleep cycles. In a comprehensive 400-page report, the researchers highlighted the “photo-toxic” nature of powerful LED lights, which can lead to irreversible loss of retinal cells and contribute to blindness. They are advocating for a reassessment of exposure limits to these lights, particularly those used in home and street lighting, as well as in offices and industries. While standard LED screens on devices like phones and laptops are deemed safe, the intense bulbs employed in car headlights pose significant risks to eye health.
