Wearing contact lenses can be a game-changer for your vision and style, but only if you use them correctly. Many people unknowingly make mistakes that can lead to discomfort, infections, or even long-term damage. Whether you're new to lenses or a seasoned wearer, it's easy to slip into bad habits.
In this guide, we'll walk you through seven common contact lens mistakes and how to avoid them. By following these tips, you'll keep your eyes healthy and your lenses comfortable, so you can enjoy clear vision and stunning eye colors without worry.
1. Sleeping in Your Contact Lenses
One of the most common mistakes is sleeping with your contact lenses in, even if they're labeled as 'extended wear.' Your eyes need oxygen, and when you sleep, your eyelids close off the cornea, reducing oxygen flow. Sleeping in lenses can increase the risk of corneal ulcers and infections.
Even if you only nap for 20 minutes, it's not worth the risk. Always remove your lenses before sleeping, and if you're prone to dozing off, keep a lens case and solution by your bedside as a reminder.
2. Using Tap Water to Rinse or Store Lenses
Tap water contains microorganisms that can cause serious eye infections, such as Acanthamoeba keratitis. It's a common mistake to rinse lenses or their case with water, especially when traveling or when you run out of solution.
Always use fresh contact lens solution for cleaning and storing. Never use water, saliva, or homemade saline. If you're in a pinch, carry a travel-sized solution with you to avoid the temptation.
3. Not Replacing Your Lens Case Regularly
Your lens case can harbor bacteria and fungi if not cleaned and replaced regularly. Many people forget to change their case, using the same one for months or even years. This can lead to repeated eye infections.
Replace your lens case every three months, and clean it daily with solution (not water). Let it air dry upside down on a clean tissue. If you notice any cracks or residue, replace it immediately.
4. Wearing Lenses Beyond Their Replacement Schedule
Whether you use daily, monthly, or yearly lenses, sticking to the replacement schedule is crucial. Overwearing lenses can cause protein buildup, reduced oxygen permeability, and increased risk of infection. For example, daily lenses like the Lighly Mellow 1Day Pink are meant to be discarded after one use, and monthly lenses like the Pre college Brown should be replaced every month.

Mark your calendar or set reminders on your phone to replace your lenses on time. If you're unsure about your schedule, check the packaging or consult your eye care professional.
5. Using Damaged or Torn Lenses
Contact lenses can get tiny tears or chips, especially if handled roughly or dropped. Wearing a damaged lens can scratch your cornea and cause discomfort or infection. Always inspect your lens before inserting it.
If you notice any damage, dispose of the lens and use a fresh one. For monthly lenses like the Romantea Betty Ash Brown, always have a spare pair on hand to avoid the temptation to wear a damaged lens.
6. Not Washing Your Hands Properly
Handling lenses with dirty hands transfers oils, dirt, and bacteria to your lenses and eyes. Many people wash their hands quickly or forget to dry them completely. This is a leading cause of eye infections.
Always wash your hands with soap and water, then dry them with a lint-free towel. Avoid lotions or soaps with oils or fragrances, as they can leave residue on your hands. If you're using makeup, apply lenses before makeup to avoid contamination.
7. Ignoring Discomfort or Redness
If your eyes feel dry, itchy, or red while wearing lenses, it's a sign that something is wrong. Some people ignore these symptoms, thinking they'll go away, but this can lead to serious complications like corneal ulcers or infections.
Remove your lenses immediately if you experience discomfort. If symptoms persist, see an eye care professional. Don't wear lenses until your eyes feel completely normal again. For those with astigmatism, toric lenses like the Kiralet Gray Toric are designed to fit properly, but if they cause discomfort, consult your doctor.
Avoiding these common contact lens mistakes is essential for maintaining healthy eyes and comfortable wear. By following proper hygiene, replacement schedules, and listening to your eyes, you can enjoy the benefits of contact lenses without the risks. Remember, when in doubt, always consult your eye care professional.
