We often see tourists on the main street in <a class=\"wpil_keyword_link\" href=\"https:\/\/vbansko.com\/en\/for-bansko\/\" title=\"Bansko\" data-wpil-keyword-link=\"linked\" data-wpil-monitor-id=\"4448\">Bansko<\/a> with branded city glasses, planning to climb to the top with them. This is a mistake. The sun in the high mountain is a completely different \u201cbeast\u201d than that on the seashore, and Pirin has its own specific traps.<\/p>\n<p>In this second part of the series on &quot;The Ten Most Important Elements&quot;, we will understand why the white rocks of Vihren act like a mirror and how to protect our eyes and skin from serious damage.<\/p>\n<h2 style=\"color: #2c3e50;border-bottom: 2px solid #e74c3c;padding-bottom: 10px;margin-top: 30px\">Why is the sun in Pirin so aggressive?<\/h2>\n<p>There are two main reasons why burning at 2500 meters above sea level happens much faster:<\/p>\n<ul style=\"list-style-type: square;margin-left: 20px\">\n<li><strong>Thin atmosphere:<\/strong> As altitude increases, the atmosphere that filters UV rays thins. For every 1000 meters, UV radiation increases by about 10-12%.<\/li>\n<li><strong>The mirror effect (Albedo):<\/strong> The snow reflects up to 80-90% of the sun&#039;s rays. But in Pirin we also have a specific factor - the white marble. Even in summer, the rocks around <a class=\"wpil_keyword_link\" href=\"https:\/\/vbansko.com\/en\/koncheto-pirin-palna-encyclopedia\/\" title=\"The horse\" data-wpil-keyword-link=\"linked\" data-wpil-monitor-id=\"2482\">The horse<\/a> and Vihren reflect light much more strongly than granite mountains (like Rila), attacking your eyes and skin from all directions, even from the bottom up.<\/li>\n<\/ul>\n<h2 style=\"color: #2c3e50;margin-top: 30px\">Eyes: The most vulnerable area<\/h2>\n<p>Forgetting your sunglasses can lead to a condition known as <strong>snow blindness<\/strong> (photokeratitis). This is literally a \u201cburn\u201d of the cornea of the eye. Symptoms appear a few hours later \u2013 a feeling of sand in the eyes, severe pain, tearing, and the inability to open your eyes.<\/p>\n<h3 style=\"color: #e67e22\">What glasses should we choose?<\/h3>\n<p>City glasses are usually Category 2 or 3. For high mountains you need specialized models. Here&#039;s how to navigate the levels of protection:<\/p>\n<table style=\"width: 100%;border-collapse: collapse;margin: 20px 0;font-size: 0.9em\">\n<thead>\n<tr style=\"background-color: #2c3e50;color: white\">\n<th style=\"padding: 12px;border: 1px solid #ddd\">Category (Cat.)<\/th>\n<th style=\"padding: 12px;border: 1px solid #ddd\">Light transmittance<\/th>\n<th style=\"padding: 12px;border: 1px solid #ddd\">Purpose<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding: 10px;border: 1px solid #ddd\"><strong>Category 2<\/strong><\/td>\n<td style=\"padding: 10px;border: 1px solid #ddd\">18% \u2013 43%<\/td>\n<td style=\"padding: 10px;border: 1px solid #ddd\">Cloudy weather, urban environment. <strong>They are not suitable for Pirin.<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px;border: 1px solid #ddd\"><strong>Category 3<\/strong><\/td>\n<td style=\"padding: 10px;border: 1px solid #ddd\">8% \u2013 18%<\/td>\n<td style=\"padding: 10px;border: 1px solid #ddd\">Standard for mountains and sea.

These block peripheral light that would otherwise enter from the sides and damage your retina.\n    <\/div>\n<p>The mountain is a place for pleasure, not pain.
