Blokz\u00ae <a href=\"\/blokz-blue-light-glasses\" aria-label=\"Visit Blue Light Lenses Page\">Blue Light Lenses<\/a> can be added to almost any pair of Zenni glasses for an affordable pair of <a href=\"\/b\/blokz-blue-light-glasses\" aria-label=\"Visit blue light glasses Page\">blue light glasses<\/a> that help protect your eyes from harmful UV and blue light emitted from digital screens, artificial light, and the sun.\u00a0 And, yes, they do make a difference!<\/p>\n<p>One of the coolest parts about offering Blokz\u00ae is\u00a0getting to demonstrate in person how the lenses block out harmful light using a <a href=\"\/p\/blue-light-laser-pen\/A1104021\/A110402124\" aria-label=\"Visit blue light laser pen Page\">blue light laser pen<\/a>. Since we can\u2019t personally visit every one of you, we decided to do the next best thing and offer a Zenni blue light laser pen that you can use at home, so you can see for yourself how your Blokz block blue light. The blue light laser pen emits 405 \u00b1 10 nm blue light to help illustrate the blue-light-blocking qualities of Blokz.<\/p>\n<p><iframe title=\"YouTube video player\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\" data-src=\"https:\/\/www.youtube.com\/embed\/2Nwcd5d9iXM\" class=\"optanon-category-C0004\"><\/iframe><\/p>\n<h2>How to Use the Blokz Blue Light Pen<\/h2>\n<p>Before using your new laser pen, you first need to unscrew the top and peel off the sticky disc cover that is over the battery to activate it. Next, place your Blokz\u00ae on a table against a light color. Press the button on the laser pointer to emit a beam of high-energy visible (HEV) blue light, and point it at the Blokz lenses. Watch as the Blokz lenses block out the blue light. Try the laser pen with other glasses (even sunglasses) to test if they protect from HEV blue light. Without blue blocker protection, the blue light beam will shine right through the lens.<\/p>\n<h2>Safety Precautions<\/h2>\n<p>When using the Blokz blue light pen, there are a few important safety measures: This is not a toy! Keep out of reach of children.<\/p>\n<ul>\n<li style=\"font-weight: 400;\">Don\u2019t aim the laser beam into the eye or look into the aperture of the pointer.<\/li>\n<li style=\"font-weight: 400;\">Never aim or shine the laser pointer at anyone.<\/li>\n<li style=\"font-weight: 400;\">Don\u2019t test the laser beam on Blokz lenses while wearing them, since small amounts of blue light may still pass through the lens.<\/li>\n<\/ul>\n<p>Order your pair of <a href=\"\/b\/blokz-blue-light-glasses\" aria-label=\"Visit Blue Light Glasses Page\">Blue Light Glasses<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":null,"protected":false},"author":1,"featured_media":63236,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[168,157,153],"tags":[],"class_list":["post-63230","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blue-light-glasses","category-billboard","category-how-to"],"acf":[],"contentshake_article_id":"","_links":{"self":[{"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/posts\/63230","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/comments?post=63230"}],"version-history":[{"count":5,"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/posts\/63230\/revisions"}],"predecessor-version":[{"id":97190,"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/posts\/63230\/revisions\/97190"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/media\/63236"}],"wp:attachment":[{"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/media?parent=63230"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/categories?post=63230"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.zennioptical.com\/blog\/wp-json\/wp\/v2\/tags?post=63230"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
