The article explains why even a few seconds of direct viewing of a solar eclipse without special protection is dangerous for eyesight. Doctors warn that there is no safe time limit, and even a brief glance can lead to solar retinopathy—a burn to the retina. The main danger is that during an eclipse, illumination decreases, causing the pupils to dilate and let in more light, while the remaining visible fragment of the Sun emits a powerful stream that focuses on the macula. Damage occurs painlessly, and symptoms appear after several hours: a dark spot in the center of vision, blurriness, distortion of lines, and impaired color perception. There is no specific treatment; vision may partially recover, but consequences often remain for life. Regular sunglasses, homemade filters, and optics without special solar filters do not protect. It is recommended to use only certified eclipse glasses, except during the brief phase of totality when the Moon completely covers the Sun.
