When the lenses are exposed to sunlight, the molecules change their structure and the lenses gradually darken. Once the UV radiation is reduced (for example, by moving indoors), the reaction is reversed and the lenses lighten again. <strong>The whole process takes only a few seconds to minutes<\/strong>, depending on the specific type of lens and the intensity of the light (UV). In general, the more modern types of self-tinting lenses (e.g. Transitions\u00ae Gen S\u2122, ColorMatic\u00ae X) react very quickly.   <\/p>\n\n<p class=\"wp-block-paragraph\">Interestingly, <strong>some types of<\/strong> self-tinting lenses <strong>react to the amount of UV radiation<\/strong>, while other, special types <strong>react to the amount of light hitting the glasses<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">An absolute novelty is<strong> Transitions ColorTouch<\/strong> - self-tinting lenses in <strong>trendy shades<\/strong> (Sapphire, Ruby, Emerald, Amethyst, Amber) that do not tint to a completely clear state in the room, but retain a light colour tone that adds a distinctive style to each wearer and gives the glasses an exclusive look.<\/p>\n\n<h3 class=\"wp-block-heading\"><strong>How do photochromic lenses work in winter?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">The winter season is specific for photochromic lenses and often surprises even experienced users in terms of functionality. Photochromic glasses are <strong>especially recommended for winter sports<\/strong>, where they combine:   <\/p>\n\n<ul class=\"wp-block-list\">\n<li>anti-glare protection,  <\/li>\n\n\n\n<li>UV radiation  <\/li>\n\n\n\n<li>and mechanical eye protection against wind and snow.  <\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">However, it should also be said that in winter, photochromic lenses may be slower to return to their clear state after going indoors. Again, this is due to the lower temperature, which slows down the back reaction of the molecules. <\/p>\n        <div class=\"component component-post-cite my-12 xl:my-24\">\n          <div class=\"container\">\n            \t\n\t\t<div class=\"mb-12\">\n\t\t\t<div class=\"text-xl md:text-3xl xl:text-4xl xl:leading-snug mb-8\">\n\t\t\t\t<p>\u201cWe often find that clients are surprised that photochromic lenses discolour faster in winter than in summer. This is due to the fact that the chemical reaction takes place more efficiently at lower temperatures. Conversely, the onset of colouration can be slower in hot weather, which is a&nbsp;very normal feature of the technology.\u201d&nbsp;<\/p>\n\n\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"flex items-center gap-6\">\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"size-16 rounded-full overflow-hidden flex-shrink-0\">\n\t\t\t\t\t\t\t        <picture class=\"inline\">\n                      <source srcset=\"https:\/\/www.aleszejdl.cz\/wp-content\/cache\/image\/128x128-crop\/adam-macsai-e1728551682142-1.avif\" type=\"image\/avif\" width=\"128\" height=\"128\">\n                <img decoding=\"async\" src=\"https:\/\/www.aleszejdl.cz\/wp-content\/uploads\/adam-macsai-e1728551682142-1.jpg\" width=\"266\" height=\"266\" alt=\"\" loading=\"lazy\" class=\"max-w-full h-auto w-full h-full object-cover\">\n        <\/picture>\n\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t<div>\n\t\t\t\t\t\t<div class=\"font-bold text-xl\">\n\t\t\t\t\t\t\tAdam M\u00e1scai\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"text-sm md:text-base text-secondary\">\n\t\t\t\t\t\t\t\toptician\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t          <\/div>\n      <\/div>\n\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.aleszejdl.cz\/wp-content\/uploads\/fotochromaticke-cocky-1-1024x683.png\" alt=\"lady with Transitions photochromic glasses with ruby color\" class=\"wp-image-7905\" srcset=\"https:\/\/www.aleszejdl.cz\/wp-content\/uploads\/fotochromaticke-cocky-1-1024x683.png 1024w, https:\/\/www.aleszejdl.cz\/wp-content\/uploads\/fotochromaticke-cocky-1-300x200.png 300w, https:\/\/www.aleszejdl.cz\/wp-content\/uploads\/fotochromaticke-cocky-1-768x512.png 768w, https:\/\/www.aleszejdl.cz\/wp-content\/uploads\/fotochromaticke-cocky-1-1536x1025.png 1536w, https:\/\/www.aleszejdl.cz\/wp-content\/uploads\/fotochromaticke-cocky-1.png 1619w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<h2 class=\"wp-block-heading\"><strong>Advantages and disadvantages of photochromic glasses<\/strong><\/h2>\n\n<h3 class=\"wp-block-heading\"><strong>Advantages of photochromic glasses<\/strong><\/h3>\n\n<ul class=\"wp-block-list\">\n<li><strong>Eye protection<\/strong> - Photochromic lenses automatically regulate the amount of light entering the eye while providing permanent protection from harmful UV rays. This helps to protect not only the vision itself, but also the eye area from the long-term negative effects of UV radiation. <\/li>\n\n\n\n<li><strong>Convenience<\/strong> - You don't have to constantly change sunglasses with different tint intensities or take them off. You will appreciate this especially when playing sports. <\/li>\n\n\n\n<li><strong>Overall money saving<\/strong> - Thanks to their adaptability, photochromic glasses can replace multiple types of glasses.<\/li>\n\n\n\n<li><strong>Reduce eye fatigue<\/strong> - The smooth change of lens tint <strong>helps reduce eye strain during transitions <\/strong>between different lighting conditions (light to shade).<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\"><strong>Disadvantages of photochromic glasses<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Although photochromic glasses offer high comfort and are a very versatile tool, they <strong>are not the ideal solution for everyone and every situation.<\/strong> From a professional point of view, it is important to know their limits so that expectations match reality.<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>They don't always achieve maximum darkening<\/strong> - Photochromic lenses do adjust to light intensity, but in most cases they don't achieve as dark a tint as conventional sunglasses.<\/li>\n\n\n\n<li><strong>Limited functionality for drivers<\/strong> - Car windscreens largely filter UV radiation, which means that some lenses in the car get little or no tint.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><strong>Tip<\/strong>: However, <a href=\"https:\/\/www.transitions.com\/cs-cz\/products\/drivewear-transitions\/\">Transitions\u00ae Drivewear\u00ae<\/a> provide optimum vision experience and colour contrast when driving as they respond to both UV and visible light. The lens colour and level of darkening adjust to the light conditions while driving. <\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Delay in colour changes<\/strong> - The transition between clear and dark is not instantaneous. For some types of photochromic lenses it can take tens of seconds to several minutes (affected by temperature, light intensity or age of the lenses). <\/li>\n\n\n\n<li><strong>Higher purchase price<\/strong> - Photochromic lenses are more technologically complex than conventional clear lenses, which is reflected in their price.  <\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\"><strong>Photochromic bicycle glasses<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">When cycling, the eyes are exposed to <strong>rapidly changing light conditions<\/strong>. The great advantage of self-darkening lenses is that <strong>you can use<\/strong> them both <strong>during sunny days<\/strong> and when it is <strong>cloudy<\/strong>. When cycling, you need to protect your eyes not only from glare and UV rays, but also<strong> from insects and foreign bodies<\/strong>, which photochromic glasses do very well (+ you can wear them when the sun is low because they are almost clear).    <\/p>\n\n<p class=\"wp-block-paragraph\">In the eye studio we recommend glasses to all cyclists:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>with a wide enough field of view,<\/li>\n\n\n\n<li>with quality optics without optical distortion,<\/li>\n\n\n\n<li>adapted to the specific shape of the face.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">The reaction speed of photochromic lenses is also very important in sports. Modern sports photochromic lenses can adapt to light changes within seconds, which significantly increases both comfort and safety. <\/p>\n        <div class=\"component component-post-cite my-12 xl:my-24\">\n          <div class=\"container\">\n            \t\n\t\t<div class=\"mb-12\">\n\t\t\t<div class=\"text-xl md:text-3xl xl:text-4xl xl:leading-snug mb-8\">\n\t\t\t\t<p>\u201cWe know from experience that slower or lower quality photochromic lenses can be more of a&nbsp;nuisance than a&nbsp;benefit in dynamic motion, so their selection is crucial.\u201d&nbsp;<\/p>\n\n\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"flex items-center gap-6\">\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"size-16 rounded-full overflow-hidden flex-shrink-0\">\n\t\t\t\t\t\t\t        <picture class=\"inline\">\n                      <source srcset=\"https:\/\/www.aleszejdl.cz\/wp-content\/cache\/image\/128x128-crop\/adam-macsai-e1728551682142-1.avif\" type=\"image\/avif\" width=\"128\" height=\"128\">\n                <img decoding=\"async\" src=\"https:\/\/www.aleszejdl.cz\/wp-content\/uploads\/adam-macsai-e1728551682142-1.jpg\" width=\"266\" height=\"266\" alt=\"\" loading=\"lazy\" class=\"max-w-full h-auto w-full h-full object-cover\">\n        <\/picture>\n\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t<div>\n\t\t\t\t\t\t<div class=\"font-bold text-xl\">\n\t\t\t\t\t\t\tAdam M\u00e1scai\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"text-sm md:text-base text-secondary\">\n\t\t\t\t\t\t\t\toptician\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t          <\/div>\n      <\/div>\n\n<h3 class=\"wp-block-heading\"><strong>Photochromic bike glasses with diopters<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">There are various solutions for cyclists with dioptric correction - from <strong>dioptric sports lenses to glasses with a dioptric insert. <\/strong>Each option has its own specifics and is not suitable for everyone.<\/p>\n\n<p class=\"wp-block-paragraph\">During a personal consultation, we help you choose a solution that:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>maintains optical quality even at higher diopters,<\/li>\n\n\n\n<li>will not restrict peripheral vision,<\/li>\n\n\n\n<li>will be compatible with the specific sport frame.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">For cyclists, we often have to deal not only with the colour of the lenses themselves, but also with their shape and curvature to avoid distortion of the image in the peripheral vision, which is essential for safety when riding.<\/p>\n\n<p class=\"wp-block-paragraph\">In our offer you will find a large number of models with self-tinting lenses.
