When is it a Bad Idea to Wear Contact Lenses?

Contact lenses are a convenient alternative to glasses, offering clear vision without the hassle of smudges or breakage. However, improper use and bad habits can put your eye health at risk. While contacts are generally safe when used correctly, there are certain situations where wearing them can do more harm than good. Here’s when you should give your eyes a break from contact lenses and some best practices to keep your vision healthy.

1. Wearing Contacts for Too Long

Your eyes need oxygen, and wearing contacts for extended periods can reduce the amount that reaches your cornea. Most people should not wear their lenses for more than 10-12 hours a day. Prolonged wear can lead to discomfort, dryness and, in severe cases, corneal ulcers or even vision loss. To keep your eyes healthy, always have a pair of prescription glasses on hand and give your eyes a break when needed.

2. Sleeping in Your Contacts

Even if your contacts are labeled as extended wear, sleeping in them is risky. Contacts already limit oxygen flow to the eyes and keeping them in overnight further increases the risk of infection. In fact, studies show that sleeping in contact lenses raises your risk of an eye infection by 6 to 8 times. If you accidentally fall asleep with them in, remove them as soon as possible and use artificial tears to rehydrate your eyes.

3. Wearing Contacts in Water

Whether it’s in the shower, pool or hot tub, water and contact lenses don’t mix. Water can cause contacts to change shape, making them uncomfortable and less effective. Worse, bacteria and microorganisms in the water can stick to your lenses, increasing the risk of eye infections like Acanthamoeba keratitis, a rare but serious condition that can lead to vision loss. If you need vision correction while swimming, consider using prescription goggles instead.

4. Not Replacing Lenses as Directed

Contacts aren’t meant to last forever. Whether you wear daily, biweekly or monthly lenses, it’s important to follow the recommended replacement schedule. Over time, protein deposits and bacteria build up on the lenses which can cause irritation, infections and reduced oxygen flow to the cornea. Using lenses past their expiration date increases the risk of complications, so always replace them on time.

5. Skipping Proper Hygiene

Your hands carry bacteria, and if you don’t wash them before handling your contacts, you risk transferring germs directly to your eyes. Always wash your hands thoroughly with soap and water before inserting or removing lenses. Additionally, never reuse old contact solution—always use fresh solution to disinfect your lenses properly.

6. Ignoring Signs of Eye Irritation

If your eyes feel dry, itchy or irritated, take your contacts out immediately. Persistent discomfort could be a sign of dry eye syndrome, an allergic reaction or an infection. Artificial tears can help with dryness, but if the irritation persists, switch to glasses and consult your eye doctor.

7. Avoiding Routine Eye Exams 

Your contact lens prescription can change over time and skipping regular eye exams can lead to wearing the wrong prescription which may cause eye strain, headaches or blurry vision. Additionally, an eye doctor can detect early signs of infections or complications before they become serious. Annual check-ups ensure your vision remains clear and your contacts continue to be safe for your eyes.

Contact lenses are a fantastic vision solution when used correctly, but they require proper care and attention. Avoid wearing them in risky situations, follow good hygiene practices and give your eyes a break when needed. If you experience persistent discomfort, redness or blurred vision, consult your eye doctor immediately. Your eyes work hard for you—treat them well, and they’ll return the favor with clear, healthy vision.
