Why Halloween Raises the Question
Halloween is a time for costumes, creativity, and experimenting with new looks; including bold coloured contact lenses. Whether you’re aiming for vampire red, cat-eye yellow, or mystical green, coloured lenses can completely transform a costume and add an extra layer of realism. But with all the excitement of the season, it’s easy to forget proper lens care, and one question often arises: can you sleep with your contact lenses?
Understanding the risks of sleeping in lenses, especially coloured or novelty contacts, is important for keeping your eyes healthy while enjoying the convenience and fun of these lenses during Halloween. Sleeping with contact lenses, especially coloured or novelty lenses, is not recommended because it reduces oxygen to the eyes and increases the risk of irritation, infection, and other complications.
What Happens When You Sleep With Contact Lenses
Your eyes rely on a steady supply of oxygen to remain healthy. When you blink, oxygen passes through your tears to the cornea, helping to maintain clear, comfortable vision. Contact lenses allow some oxygen to pass through, but closing your eyes for hours during sleep limits this supply.
Reduced Oxygen Flow
Sleeping in contact lenses restricts oxygen to your cornea, which can lead to dryness, irritation, or swelling. Coloured lenses, which often have additional pigment layers, may slightly reduce oxygen permeability compared to standard lenses. This makes following recommended wear schedules even more important during seasonal use.
A Breeding Ground for Bacteria
When lenses are left in overnight, tear circulation is limited, and debris and bacteria aren’t cleared as effectively. This warm, moist environment can increase the risk of eye infections. While one night of sleeping in lenses doesn’t always cause serious issues, repeated use raises the likelihood of complications such as keratitis or corneal ulcers.
Are Coloured Contacts Safe for Extended Wear?
Some contact lenses are approved for overnight wear, but most novelty and Halloween-style coloured contacts are designed for short-term use only. These lenses are meant to be worn for a few hours at a time and then removed and properly cleaned or discarded. Wearing them overnight can increase the risk of eye irritation and infection, even if the lenses feel comfortable at first.
Not Everyone’s Eyes Respond the Same
Even with durable lenses, some eyes are more sensitive than others. Factors such as dry eye, allergies, or existing eye conditions can make overnight wear more risky. It’s important to check with your optometrist before attempting any extended or overnight wear, particularly with coloured or decorative lenses.
Risks of Sleeping in Coloured Contact Lenses
Sleeping in lenses, especially coloured ones, can create several issues:
- Dryness and irritation due to reduced oxygen supply
- Eye infections from bacteria accumulating on the lens and eye surface
- Corneal abrasions or ulcers in severe cases
- Swelling or inflammation, leading to blurred vision
- Discomfort that can persist even after removing the lenses
Why These Risks Matter
Even minor irritation can disrupt daily life, while more serious complications may affect long-term eye health. Coloured lenses can look fun and festive, but they’re medical devices that interact directly with your eyes. Following usage guidelines helps you enjoy the aesthetic benefits safely.
What to Do If You Accidentally Sleep in Your Lenses
Many people accidentally fall asleep in their lenses during busy days or while preparing for events like Halloween parties. If that happens, it’s important to take a careful approach:
- Apply sterile lubricating drops to help rehydrate your eyes before removing the lenses.
- Wait 15 to 20 minutes before taking your lenses out to reduce the chance of irritating the cornea.
- Monitor how your eyes feel afterward. Persistent pain, redness, or sensitivity to light are signals to contact an eye care professional.
Building Healthy Habits With Coloured Contacts
Healthy habits make wearing coloured contacts both safe and enjoyable. Following these guidelines supports comfort and reduces the risk of complications:
- Always wash and dry your hands before inserting or removing lenses
- Follow the manufacturer’s usage instructions carefully
- Avoid sleeping in lenses
- Use fresh solution if lenses are reusable
- Take breaks by switching to glasses when possible
- Keep regular appointments with your optometrist
By treating coloured lenses with the same care as prescription lenses, you can enjoy festive looks while keeping your eyes healthy.
