No. It’s absolutely not safe to wear contacts while immersed in water or when sleeping (unless you have contacts specifically intended for overnight wear).
Sleeping in your contact lenses can dry out your eyes and potentially harm your vision as a result of infection. Contact lenses should also be kept away from water, as it’s a natural breeding ground for bacteria and microorganisms, which can get trapped under the contact lens, putting you at risk of a waterborne eye infection.
To stay healthy, your corneas require hydration and oxygen. Blinking keeps your eyes wet, and the tears you produce allow oxygen to enter your eyes.
Sleeping in standard contact lenses limits the amount of oxygen and hydration that reaches your eyes. As a result, your corneas are drier and susceptible to corneal abrasion, and they have a harder time fighting bacteria, causing your eyes to be more prone to infection.
If, after sleeping in contact lenses, you experience blurred vision, discharge from your eyes, redness or watering, you may have an eye infection. Left untreated, infection can lead to corneal damage, and—in extreme cases—loss of vision.
Contact lens wearers are more likely to develop keratitis, an inflammation of the cornea, if their lenses come into contact with water. Left untreated, keratitis can cause vision loss.
In microbial keratitis, microorganisms invade the cornea and cause an infection of the eye. The microorganisms that cause these infections can be found in a variety of water sources, including rivers, lakes and streams, showers, tap, a pool or a jacuzzi. Normally, the antimicrobial properties of tears protect your eyes, but that process is hindered by contact lenses.
Furthermore, contact lenses can stick to your eye when exposed to water, potentially leading to corneal abrasions. These scratches may enable microorganisms found in non-sterile water to penetrate the cornea and cause an infection.
So, remove those lenses before going to bed and showering. If you experience symptoms like eye pain, discharge, or sensitivity to light, immediately remove your lenses and consult Eyesight.sg in Singapore without delay.
Almost everyone can wear contact lenses, no matter their age, prescription or lifestyle.
If you fall asleep with your contacts on, you may wake up with them attached to your eye's surface. If they don't come out easily, blink and apply lens drops until the surface of your eye is moist. That should make it easier to remove the lenses.
