Co znamen\u00e1 „jenom“ 1,00 dioptrie \u2013 a pro\u010d se to snadno p\u0159ehl\u00e9dne<\/strong><\/p>\n

Dioptrie je jednotka optick\u00e9 mohutnosti. Hodnota kolem 1,00 dioptrie na d\u00e1lku nebo do bl\u00edzka pat\u0159\u00ed k t\u011bm ni\u017e\u0161\u00edm.

Dob\u0159e vid\u011bt je relativn\u00ed: nejde jen o ostrost<\/strong><\/p>\n

Ostrost je jen jeden parametr vid\u011bn\u00ed. Vedle n\u00ed existuje cel\u00e1 \u0159ada dal\u0161\u00edch: schopnost udr\u017eet zaost\u0159en\u00ed, rychlost p\u0159eost\u0159en\u00ed mezi bl\u00edzkem a d\u00e1lkou, prostorov\u00e9 vid\u011bn\u00ed, citlivost na kontrast a hlavn\u011b v\u00fddr\u017e.
