What are the effects on our sight of these radiation to which we are constantly exposed? How can their harmful effects be avoided? <\/p>\n<p>&nbsp;<\/p>\n<h2 class=\"acPosts__titleIndented\">5 important aspects to consider:<\/h2>\n<p>&nbsp;<\/p>\n<h3><strong class=\"red\">1. Visual dysfunctions<\/strong><\/h3>\n<p>The Cromo Care filters represent an effective solution for all the people affected by the following <strong>pathologies<\/strong>:<\/p>\n<p>&nbsp;<\/p>\n<p>\u2022 <strong>Albinism<\/strong><br \/>\n\u2022 <strong>Aniridia<\/strong><br \/>\n\u2022 <strong>Aphakia and pseudophakia<\/strong><br \/>\n\u2022 <strong>Cataract<\/strong><br \/>\n\u2022 <strong>Corneal dystrophy<\/strong><br \/>\n\u2022 <strong>Diabetic retinopathy<\/strong><br \/>\n\u2022 <strong>Glaucoma<\/strong><br \/>\n\u2022 <strong>Macular degeneration<\/strong><br \/>\n\u2022 <strong>Optic atrophy<\/strong><br \/>\n\u2022 <strong>Retinitis pigmentosa<\/strong><\/p>\n<p>&nbsp;<\/p>\n<h3><strong class=\"red\">2. Harmful radiation<\/strong><\/h3>\n<p>It is essential for people suffering from these diseases to <strong>pay more attention to the harmful effects of UV rays and blue light<\/strong> on their eyesight. These filters, by correctly assimilating the harmful radiation, counteract the absorption by the orbital tissues and the consequent arise of visual complications.<\/p>\n<p>&nbsp;<\/p>\n<h3><strong class=\"red\">3. Transmittance<\/strong><\/h3>\n<p>For each Cromo Care filter is important to know the level of transmittance, that is the percentage ratio between the intensity of the light passing through the lens and that of the light that emerges. <\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-7226\" src=\"\/wp-content\/uploads\/2025\/01\/Trasmittanza-EN.jpg\" alt=\"visual lens\" width=\"100%\" \/><\/p>\n<p>&nbsp;<\/p>\n<h3><strong class=\"red\"><br \/>\n4. The wavelength<\/strong><\/h3>\n<p>A second important aspect to consider is the numerical value of the last wavelength<br \/>\nbelow which all the other wavelengths are completely absorbed by the lens. For example: if a filter has a value of 450nm, it indicates that all the wavelengths below 450nm are correctly absorbed by the filter.<\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-7226\" src=\"\/wp-content\/uploads\/2025\/01\/Wavelenght-EN.jpg\" alt=\"visual lens\" width=\"100%\" \/><\/p>\n<p>&nbsp;<\/p>\n<h3><strong class=\"red\">5. The contrast test<\/strong><\/h3>\n<p>Each filter must be chosen and used depending on the pathology and the results of the<br \/>\ncontrast sensitivity test.<br \/>\nTo obtain each filter, the lenses are immersed in special colored baths whose pigments are<br \/>\nable to selectively absorb different wavelengths. The lenses are then left in immersion<br \/>\nuntil the desired solar absorption is reached.<br \/>\nThe Cromo Care filters are recommended for people suffering from the pathologies listed<br \/>\nabove, those who tried them confirm that they have several benefits including:<br \/>\n&nbsp;<br \/>\n<strong>\u2022 clear vision in all light conditions<br \/>\n\u2022 reduction of glare and opacity<br \/>\n\u2022 optimal vision in sunny conditions<br \/>\n\u2022 improvement of contrast and visual acuity<\/strong><br \/>\n&nbsp;<br \/>\nBelow you can find a table with some indications about the Cromo Care filters to use<br \/>\naccording to different visual needs:<\/p>\n<p>[cromo-care]<\/p>\n","protected":false},"featured_media":1101,"template":"","meta":{"_acf_changed":false},"categoria-academy":[],"class_list":["post-1277","academy","type-academy","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.ltllenses.it\/en\/wp-json\/wp\/v2\/academy\/1277","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ltllenses.it\/en\/wp-json\/wp\/v2\/academy"}],"about":[{"href":"https:\/\/www.ltllenses.it\/en\/wp-json\/wp\/v2\/types\/academy"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ltllenses.it\/en\/wp-json\/wp\/v2\/media\/1101"}],"wp:attachment":[{"href":"https:\/\/www.ltllenses.it\/en\/wp-json\/wp\/v2\/media?parent=1277"}],"wp:term":[{"taxonomy":"categoria-academy","embeddable":true,"href":"https:\/\/www.ltllenses.it\/en\/wp-json\/wp\/v2\/categoria-academy?post=1277"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
