Once that date passes, the lens should not go in your eye, even if the package looks untouched.<\/p>\n  <\/div>\n\n  <!-- BODY -->\n  <div class=\"vp-exp-body\">\n\n    <div class=\"vp-fi\">\n      <p>Contact lenses sit directly on the surface of your eye, so expiry dates deserve more attention than the date on an old bottle of shampoo or makeup. The lens material, packaging seal, and sterile solution inside the pack all need to stay in good condition. If one part is no longer reliable, the lens can put your eye at risk.<\/p>\n      <p>There&#8217;s also a second timeline to watch. Contact lenses have a printed expiry date before opening, but they also have a replacement schedule after you start wearing them. A daily lens, a two-week lens, a monthly lens, and an extended-wear lens all follow different rules.<\/p>\n    <\/div>\n\n    <hr class=\"vp-rule\">\n\n    <div class=\"vp-fi\">\n      <h2>Where Can You Find the Expiry Date?<\/h2>\n      <p>You can find the expiry date on the contact lens box and on the individual blister pack.<\/p>\n\n      <div class=\"vp-find-card\">\n        <h3>How to locate it<\/h3>\n        <div class=\"vp-find-steps\">\n          <div class=\"vp-find-step\"><div class=\"vp-find-num\">1<\/div><span>Look for <strong>&#8220;EXP,&#8221;<\/strong> an hourglass symbol, or a printed month and year near the prescription details.<\/span><\/div>\n          <div class=\"vp-find-step\"><div class=\"vp-find-num\">2<\/div><span>If the date is hard to read, check another blister pack from the same box.<\/span><\/div>\n          <div class=\"vp-find-step\"><div class=\"vp-find-num\">3<\/div><span>If you still can&#8217;t confirm the date, contact the retailer before wearing the lenses.<\/span><\/div>\n          <div class=\"vp-find-step\"><div class=\"vp-find-num\">4<\/div><span>If the date has passed, throw the lens away.

The blister pack holds the lens in sterile solution, and that package has to keep germs out while keeping the lens hydrated and stable.<\/p>\n      <p>Over time, the packaging seal can weaken, the solution can become less reliable, and the lens itself can change. You might not see a problem with your eyes, but that doesn&#8217;t mean the lens is safe. That&#8217;s why an unopened expired contact lens is still expired.<\/p>\n    <\/div>\n\n    <hr class=\"vp-rule\">\n\n    <div class=\"vp-fi\">\n      <h2>Can You Wear Expired Contact Lenses?<\/h2>\n\n      <div class=\"vp-warn\">\n        <div class=\"vp-warn-icon\">\u26a0\ufe0f<\/div>\n        <div class=\"vp-warn-body\">\n          <h3>No \u2014 do not wear expired contact lenses.<\/h3>\n          <p>Expired lenses can raise the risk of eye irritation, infection, redness, discomfort, and blurry vision.

Reusable lenses collect deposits from tears, solution, and the environment over time. Cleaning helps, but it does not make a lens last forever.<\/p>\n      <p>Monthly or two-week lenses also have limits.
