What Are Overnight Contact Lenses?

Imagine this: slipping into bed wearing special lenses designed just for your eyes and waking up to a world that’s already crystal clear. That means no glasses or contacts to fuss with during the day. Sounds like a dream? Overnight contact lenses make it real.

These lenses gently reshape your cornea (the front part of your eye) while you sleep, giving you clear vision when you wake. It’s a simple, non-surgical way to see your best without the hassle of daytime lenses.

How Overnight Lenses Work

Our eyes focus light through the cornea, and when its shape is a little off, things get blurry. Overnight lenses carefully and temporarily reshape your cornea’s curve during sleep, which adjusts how light hits your retina.

The lenses apply gentle pressure to flatten the center of your cornea overnight, which can correct common vision problems like nearsightedness (myopia) and mild astigmatism. When you wake up, you remove the lenses and enjoy clear vision throughout the day.

This effect typically lasts 24 to 48 hours, so you’ll need to wear the lenses every night to maintain sharp vision without glasses or daytime contacts.

Who Might Benefit From Overnight Lenses?

Overnight lenses can benefit a variety of lifestyles due to how it allows clear vision for long hours without the schedule of daily disposables or the potential drawbacks of glasses.

Here are some specific groups that can benefit from overnight lenses:

Busy movers and shakers: If glasses or daytime lenses get in your way during work, sports, or outdoor activities, overnight lenses can help with that.

Kids and teens: Overnight lenses can potentially slow the progression of nearsightedness in growing eyes, which can be a big help for parents looking to protect their kids’ vision long term.

People with dry or sensitive eyes: Since you’re not wearing lenses during the day, your eyes get a break from dryness or irritation.

Adventurers and swimmers: Thanks to overnight lenses, forget fumbling with glasses or contacts during activities and instead wake up ready to go.

Anyone seeking convenience: If you want less hassle during your busy day, overnight lenses could be your new favorite routine.
