Ve st\u0159edu 12. srpna 2026 budeme moci pozorovat \u00fapln\u00e9 zatm\u011bn\u00ed Slunce, kter\u00e9 u n\u00e1s bude viditeln\u00e9 jako \u010d\u00e1ste\u010dn\u00e9 s maxim\u00e1ln\u00ed f\u00e1z\u00ed p\u0159ibli\u017en\u011b 0,89. Za\u010d\u00e1tek zatm\u011bn\u00ed v Praze p\u0159ipad\u00e1 na 19.19, maxim\u00e1ln\u00ed f\u00e1ze nast\u00e1v\u00e1 ve 20.12. Slunce zapad\u00e1 nedlouho po tomto okam\u017eiku ve 20.24.<\/p>\r\n

\u00dakaz bude pozorovateln\u00fd i pouh\u00fdma o\u010dima, ale pouze se speci\u00e1ln\u00edmi br\u00fdlemi, nebo\u0165 bez pou\u017eit\u00ed vhodn\u00fdch ochrann\u00fdch pom\u016fcek se pozorovatel vystavuje nebezpe\u010d\u00ed v\u00e1\u017en\u00e9ho a trval\u00e9ho po\u0161kozen\u00ed zraku!<\/p>\r\n

Pro\u010d je nebezpe\u010dn\u00e9 pou\u017e\u00edvat pro pozorov\u00e1n\u00ed Slunce p\u0159edm\u011bty \u00a0jako slune\u010dn\u00ed br\u00fdle, disketa, CD, DVD, o\u010douzen\u00e9 sklo?\u00a0<\/strong><\/p>\r\n

Kv\u016fli ztmaven\u00ed Slunce t\u011bmito p\u0159edm\u011bty (tedy omezen\u00ed pr\u016fchodu viditeln\u00e9ho sv\u011btla), se zorni\u010dka rozt\u00e1hne. Do oka pronikne v\u00edce z\u00e1\u0159en\u00ed, kter\u00e9 jimi nen\u00ed odst\u00edn\u011bno (\u0161kodliv\u00e9 ultrafialov\u00e9 a infra\u010derven\u00e9). To trvale po\u0161kozuje zrak, ultrafialov\u00e9 sv\u011btlo bu\u0148ky po\u0161kod\u00ed biochemicky, infra\u010derven\u00e9 pak s\u00edtnici nen\u00e1vratn\u011b sp\u00e1l\u00ed. Proto\u017ee s\u00edtnice nem\u00e1 receptory bolesti, takov\u00e9 po\u0161kozen\u00ed zraku nebol\u00ed. Typicky se projev\u00ed a\u017e o n\u011bkolik hodin pozd\u011bji. Nikdy proto dostate\u010dnou ochranu zraku nepodce\u0148te.\u00a0<\/p>\r\n
