Can you share contacts?

It’s a hot debate whether certain items should be shared, like bank accounts, clothing, or even toothbrushes. But when it comes to sharing contact lenses? Opticians say: no way, José.  

Now you may be wondering if this rule only applies to prescription lenses, and you can still borrow or lend colored contacts around Halloween — most people only wear colored contacts for one night, right? Well, we hate to break it to you, but sharing contact lenses of any kind is a big no-no. Here’s why. 

First, contact lenses sit directly on your eye, so your risk of a bacterial infection grows exponentially. You and Jamie may be roommates, but your eyes are about to host some unwanted roommates the second you borrow her lenses for the day. Eye infections like pink eye (conjunctivitis), ocular herpes (virus that causes cold sores), or even yeast infections can occur after sharing contacts, so it’s best to keep anything contact-related to yourself to avoid those risks. 

Symptoms of an eye infection may include: 

  • Eye discharge
  • Red or swollen eyes
  • Itchy eyes
  • Swelling around the eyes
  • Blurry vision
  • Watery eyes
  • Severely dry eyes

The second reason to avoid sharing contacts is that contact lenses are not one-size-fits-all. It’s rare that your eyes will have the same measurements, let alone the same vision prescription as your friends or family, so you’re better off ordering lenses right for you.  

While it may seem like colored contacts are in a similar vein as costume jewelry, they need to be the right size for your eye to ensure a comfortable, safe fit. Think of it as wearing a pair of sandals in the wrong size. Contacts that don’t properly fit your eye can irritate and even injure your corneas, potentially leading to serious conditions such as corneal ulcers. (Similar to those pesky blisters you get on your heels from wearing the wrong shoes, ouch.) 

Can you share contacts with family members?

Occasionally, we see instances where a family member accidentally gets their contacts confused with another family member and a few minutes our hours go by without them realizing. Even in this case, we recommend throwing that pair out and getting a fresh pair. Mistakes happen, but no situation is worth risking your eye health. 

When it comes to your eyes, protection is key. Say no to borrowing or lending contacts, and when in doubt, get a fresh pair! Your eyes will thank you.
