October brings pumpkins, parties, and plenty of costumes but it also brings a spike in preventable eye injuries. At SightMD, we see more Halloween-related eye problems than at any other time of year, most often linked to decorative contact lenses, heavy makeup, glitter, and costume props. While these accessories may seem harmless, the FDA, CDC, and American Academy of Ophthalmology (AAO) all warn that they can cause serious complications, including painful abrasions, infections, and even permanent vision loss.

This comprehensive SightMD Halloween Eye Safety Guide covers everything you need to know—from the laws around costume lenses to makeup safety, glitter risks, glow-stick emergencies, and when to call an eye doctor. Whether you’re going all-out for your costume or helping a child get dressed for trick-or-treating, these tips ensure the fun never turns frightening.

Costume Contacts 101: Why a Prescription Is Non-Negotiable

One of the biggest Halloween myths is that decorative lenses, sometimes called cosmetic, colored, fashion, theatrical, or Halloween contacts—are “just accessories.” In reality, the FDA classifies all contact lenses as medical devices, which means:

• They legally require a valid prescription and professional fitting, even if they don’t correct vision.
• It is illegal to sell them without a prescription, whether online or in stores.

The FDA emphasizes that many non-prescription costume lenses are poorly manufactured, non-sterile, or improperly sized, which can cut, scratch, or suffocate the cornea. The AAO adds that ill-fitting lenses can cause corneal abrasions, painful ulcers, and bacterial keratitis, a rapidly progressing infection that can lead to permanent vision loss in as little as 24–48 hours.

Where should you not buy them?
Anywhere that doesn’t ask for your prescription, including beauty supply stores, novelty shops, convenience stores, flea markets, Halloween pop-ups, and unverified online retailers.

Where should you buy them?
From a vendor that requires a prescription from your eye doctor after a proper fitting.

If decorative lenses are part of your costume plan, schedule a contact lens exam with SightMD so your lenses fit safely, comfortably, and legally.

Safe-Use Checklist for Doctor-Prescribed Lenses

Even properly fitted decorative lenses can cause problems if not cared for correctly. The CDC and AAO consistently warn that poor hygiene is one of the top causes of lens-related infections.

Use this checklist to keep your eyes safe:

1. Wash and dry your hands thoroughly before handling lenses.
2. Use fresh solution every time. Never “top off” or reuse old disinfecting solution.
3. Never share lenses or lens cases. Sharing spreads bacteria, viruses, and fungi.
4. Keep lenses away from water. No swimming, showering, or rinsing lenses with tap water.
5. Do not sleep in decorative lenses. Overnight wear increases infection risk significantly.
6. Stop wearing lenses immediately if you notice redness, pain, light sensitivity, discharge, or blurred vision. These warning signs require prompt eye care.

Beyond Contacts: Safe Halloween Eye Makeup, Face Paint & Glitter

Many eye injuries during Halloween aren’t caused by lenses, they come from makeup, craft glitter, face paint, and residue that collects in the eyes throughout the night.

Choose only products designed for the eye area

The FDA stresses the importance of using cosmetics labeled safe for use around the eyes, as other products can contain pigments or materials that cause irritation or allergic reactions. Face paints and costume kits may include ingredients not meant for eyelids or lash lines.

Say no to craft glitter

The AAO strongly advises against using loose craft glitter anywhere near the eyes. These large, sharp plastic pieces can scratch the cornea—especially dangerous for contact lens wearers whose lenses trap the glitter against the eye’s surface. Opt for cosmetic-grade shimmer instead.

Avoid expired or shared makeup

Old products harbor bacteria. Sharing makeup, especially eye makeup, dramatically increases infection risk.

Remove cosmetics completely before bed

Sleeping in eye makeup—even a small amount—can block glands, increase irritation, and trap bacteria against the cornea.

Props, Masks, Glow Sticks & DIY Decorations

Halloween costumes often involve sharp plastic props, glittered masks, glow sticks, or homemade accessories. These add excitement—but also risk.

Be careful with masks

Masks that slide, poke eyelashes, or block side vision can cause falls or impact injuries. Make sure children can see clearly in all directions before wearing a mask outside.

Choose soft props

Avoid rigid or pointed items—like spears, swords, or magic wands—that can accidentally strike someone’s face or eyes.

Glow stick emergencies

Glow sticks are generally safe, but their liquid is an eye irritant. Poison Control recommends flushing with clean water for 15–20 minutes if glow-stick fluid enters the eye. After rinsing, call Poison Control (1-800-222-1222) for further guidance. Avoid rubbing the eye, which can worsen irritation.

DIY costume crafting

If you’re hot-gluing, cutting, sanding, or spray-painting costume accessories, wear protective eyewear to prevent fragments or fumes from reaching your eyes.

When Symptoms Are More Than Halloween—Call SightMD

Some Halloween eye injuries are mild, but others require urgent medical care. Seek same-day evaluation if you experience:

• Severe or increasing eye pain
• Sudden blurred or decreased vision
• Light sensitivity
• Thick discharge
• A white or cloudy spot on the eye (possible corneal ulcer)

These symptoms can signal infections like bacterial keratitis, which progresses quickly and can cause permanent visual damage. SightMD provides urgent evaluations, corneal care, and contact lens complication treatment at locations throughout New York, New Jersey, Connecticut, and Pennsylvania.
