If you’re tired after a long day or just need a quick nap, you may be tempted to simply fall asleep without taking your contact lenses out first. After all, what harm could it do? Unfortunately, the answer to that question is “quite a lot.” The simple fact of the matter is that sleeping with your contact lenses can cause major problems for your eyes. Here’s a closer look at why it’s best to always remove your contacts before heading to bed.
Why is Sleeping with Contact Lenses Dangerous?
One of the side effects of wearing contact lenses is that they restrict the amount of oxygen your eyes receive. Consequently, when you close your eyelids over your contacts to go to sleep, your eyes may not get any oxygen at all. This can cause serious damage to your cornea (the part of the eye that focuses light), leading to all kinds of complications.
On top of that, it’s possible for bacteria to get trapped underneath your contacts. If you don’t take the lenses out before going to sleep, these harmful microorganisms could be stuck against your eyes all night. As a result, you may have a higher risk of suffering from serious eye infections such as bacterial keratitis.
Finally, it should be noted that contact lenses can absorb some of the moisture in your eyes. Since your body produces fewer tears while you’re asleep, leaving your contacts in at night can easily lead to dry eye, which can result in significant discomfort and irritation.
What Should You Do If You Fall Asleep with Your Contact Lenses?
Even if you’re aware of the dangers of falling asleep with your contact lenses, it could still happen by accident every once in a while. If you wake up and realize your contacts are still in your eyes, here’s what you should do:
- Try to remove the lenses by very carefully nudging them out of your eyes. If they seem to be stuck, give them extra lubrication by using eye drops and blinking.
- Once your contacts are out, avoid wearing them again for at least a full day so that you can give your eyes a chance to rest and recover.
- Be aware of potential signs of an infection, like redness or excessive watering. If there are any concerning symptoms, call your optometrist right away to see what they recommend.
Remember, when used properly, contact lenses are a safe and effective way to improve your vision during the day. As long as you make a point of taking your contacts out every night before bed, you can continue to enjoy the benefits they have to offer while also keeping your eyes safe and healthy.
