11 Bad Contact Lens Habits That Can Ruin Your Vision

Here are 11 bad things that can happen if you don’t wear and care for your contact lenses properly.

1) Sleeping in your contacts. This is the No. 1 risk factor for corneal ulcers, which can lead to severe vision loss and the need for a corneal transplant. Your cornea needs oxygen from the atmosphere because it has no blood vessels. The cornea is already somewhat deprived of oxygen when you have your eyes closed all night, and adding a contact on top of that stresses the cornea out from lack of oxygen. You don’t need to see when you are sleeping. Take your contacts out!!!! I promise your dreams will still look the same.

2) Swimming in your contacts. Salt, fresh or pool water all have their individual issues with either bacteria or chemicals that can leach into your contacts. If you absolutely need to wear them to be safe in the water, then take them out as soon as you are done and clean and disinfect them.

3) Using tap water to clean contacts. Tap water is not sterile. See No. 2.

4) Using your contacts past their replacement schedule. The three main schedules now are daily, two weeks and monthly. Dailies are just that – use them one time then throw them away; they are not designed to be removed and re-used. Two-week contacts are designed to be thrown away after two weeks because they get protein buildup on them that doesn’t come off with regular cleaning. Monthly replacement contacts need to have both daily cleaning and weekly enzymatic cleaning to take the protein buildup off. Using your lenses outside of these schedules and maintenance increases the risk of infection and irritation.

5) Getting contacts from an unlicensed source. Costume shops and novelty stores sometimes illegally sell lenses. If you didn’t get the fit of the lenses checked by an eye doctor, they could cause serious damage if they don’t fit correctly.

6) Wearing contacts past their expiration date. You can’t be sure of the sterility of the contact past its expiration date. As cheap as contacts are now, don’t take the risk with an expired one.

7) Topping off your contact lens case solution instead of changing it. This is a really bad idea. Old disinfecting solution no longer kills the bacteria and can lead to resistant bacteria growing in your case and on your lenses that even fresh disinfecting solution may not kill. Throw out the solution in the case EVERY DAY!

8) Not properly washing your hands before inserting or removing contacts. It should be self-evident why this is a problem.

9) Not rubbing your contact lens when cleaning even with a “no rub” solution. Rubbing the lens helps get the bacteria off. Is the three seconds it takes to rub the lens really that hard? “No rub” should never have made it to market.

10) Sticking your contacts in your mouth to wet them. Yes people actually do this. Do you know the number of bacteria that reside in the human mouth? Don’t do it.

11) Not having a backup pair of glasses. This is one of my biggest pet peeves with contact lens wearers. In my 25 years of being an eye doctor, the people who consistently get in the biggest trouble with their contacts are the ones who sleep in them and don’t have a backup pair of glasses. So when an eye is red and irritated they keep sticking that contact lens in because it is the only way they can see. BAD IDEA. If your eye is red and irritated don’t stick the contact back in; it’s worst thing you can do!

Hygiene is critical to wearing your contact lenses

Contact lenses can significantly improve your vision but it’s very important to care for them properly to avoid potentially serious infections or other problems.

Your habits, supplies, and eye doctor are all essential to keeping your eyes healthy so it’s important to follow instructions for proper care and to call us if you have concerns. 

These recommendations will help extend the life of your contact lenses and keep your eyes safe and healthy. 

Your lens insertion and removal routine

• Before you handle contacts, wash and rinse your hands with a mild soap.
• Make sure the soap doesn’t have perfumes, oils, or lotions. They can leave a film on your hands.
• Dry your hands with a clean, lint-free towel before touching your contacts.
• It’s a good idea to keep your fingernails short and smooth so you won't damage your lenses or scratch your eye when inserting or removing your contacts.
• Lightly rubbing your contact in the palm of your hand with a few drops of solution helps remove surface build-up.
• Rinse your lenses thoroughly with a recommended solution before soaking the contacts overnight in a multi-purpose solution that completely covers each lens.
• Store lenses in the proper lens storage case.
• Don't use tap water or saliva to wash or store contact lenses or lens cases.
• If you use hair spray, use it before you put in your contacts.
• Put on eye makeup after you put in your lenses. Take them out before you remove makeup.
• Always follow the recommended contact lens replacement and wearing schedule prescribed.

Your supplies

• Use doctor-recommended solution.
• Rub and rinse your contact lens case with sterile contact lens solution. Never use water.
• Clean the case after each use.
• Replace your contact lens case at least once every three months. 
• Don’t “top off” solution. Use only fresh contact lens disinfecting solution in your case. 
• Never mix fresh solution with the old or used solution.
• Change your contact lens solution according to the manufacturer's recommendations.

Your eye doctor

• Visit us yearly or as often as recommended.
• Ask us if you have questions about how to care for your contacts and case or if you are having any difficulties.
• Remove your contact lenses immediately if your eyes become irritated. Call us and let us know what’s going on.
• Call us if you have any sudden vision loss, blurred vision that doesn’t get better, light flashes, eye pain, infection, swelling, unusual redness, or irritation. 

Wear your contacts safely

• Some contacts need special care and products. Always use the disinfecting solution, eye drops, and enzymatic cleaners your doctor recommends. Some eye products or eye drops aren’t safe for contact wearers.
• Saline solution and rewetting drops do not disinfect lenses.
• Use a rewetting solution or plain saline solution to keep your eyes moist.
• Don’t wear your contacts when you go swimming in a pool or at the beach.
• Don't sleep in your contact lenses unless prescribed by your eye doctor.
• Don’t clean or store your contacts in water.
• See us for your regularly scheduled contact lens and eye examination.
• If you think you’ll have trouble remembering when to change your lenses, ask for a chart to track your schedule or make one for your needs.

Be sure to call us if you have any questions about caring for your contact lenses or if you’re eyes are having problems.
