Colored contact lenses are sometimes the perfect final touch to take a Halloween costume to the next level.
Unfortunately, not all costume lenses are created equal — or with equal concern for wearer safety. With Halloween coming up, we want to give all of our costume-loving patients some guidance on how to find great costume lenses and care for them properly to protect their eye health. This focus on costume contact lenses safety is especially important during seasonal events like Halloween when decorative lenses are more popular.
Many patients ask, are costume contacts safe to wear for short periods. The answer depends on whether the lenses are prescribed, properly fitted, and cared for according to medical guidelines. Understanding costume contact lenses safety helps reduce the risk of long-term eye damage.
Are Costume Contact Lenses Safe to Wear?
A common question we hear is, are costume contacts safe when worn only for Halloween or special occasions. According to the Centers for Disease Control and Prevention, decorative lenses are not risk-free and must be treated like any other medical device. Costume contact lenses safety depends on whether the lenses are FDA regulated, prescribed by an eye doctor, and used correctly.
When lenses are FDA approved contact lenses and worn according to professional instructions, the risks are much lower. Problems arise when people ignore guidelines or purchase lenses casually. In those cases, colored contact lenses risks increase significantly, including irritation, injury, and eye infection from contacts.
Never Forget that Contact Lenses Are Medical Devices
Yes, that includes contact lenses that are only for appearance. Unlike a pair of glasses with no lenses, contact lenses are classified as medical devices whether they help you see clearly or not. Don’t just assume you can buy some costume lenses without getting a prescription even if your vision is 20/20 or better, because contact lens prescriptions are about the fit of the lenses on your corneas as much as they are about vision correction.
The FDA classifies all contact lenses, including decorative ones, as medical devices. This means FDA approved contact lenses must meet strict safety standards. Wearing contact lenses without prescription approval increases the likelihood of corneal injury and infection. A valid prescription for costume contacts ensures the lenses fit properly and support overall costume contact lenses safety.
Do I Really Need a Prescription for Decorative Lenses?
Yes. A prescription for costume contacts is required by law, even when the lenses are cosmetic. Purchasing or wearing contact lenses without prescription oversight is illegal in the United States and can expose your eyes to serious harm.
Wearing lenses without a prescription increases colored contact lenses risks, including abrasions and ulcers. Eye doctors evaluate more than vision correction when issuing a prescription for costume contacts. Fit, movement, and oxygen flow are all essential to reducing the risk of eye infection from contacts.
Beware Unscrupulous Vendors
This brings us to a common red flag when looking at costume lens vendors. If they require a prescription before they sell to you, then they are likely trustworthy. It is illegal to sell contacts in the US without requiring a prescription, so if a vendor tries that, run! You don’t know what other safety laws they’re willing to break if they’re already breaking that one, such as regulations on sanitation and quality of materials. It’s worth the money to pay a little more for lenses you know are safe.
Sellers who ignore prescription laws are often distributing illegal costume contacts. These lenses may not meet FDA manufacturing or sanitation standards. Wearing illegal costume contacts significantly increases colored contact lenses risks and the chance of developing an eye infection from contacts.
What Are the Risks of Buying Costume Contacts Online?
Buying decorative lenses online can be risky if the seller does not require a prescription. Online marketplaces are a common source of illegal costume contacts, which are often sold without verification or proper labeling.
The American Academy of Ophthalmology reports that non-prescribed lenses are associated with higher rates of corneal abrasions, ulcers, and eye infection from contacts. These outcomes highlight why costume contact lenses safety depends on avoiding contact lenses without prescription approval and choosing only FDA approved contact lenses.
Eyes Come in Different Shapes and Sizes
We touched on this already, but human eyeballs don’t all come in one identical shape and size. There’s no such thing as a one size fits all contact lens. If you try to wear a contact that doesn’t fit the particular curve of your eye, it might fall out or put you at risk of an eye injury. Just another reason that prescription is worth getting!
Poorly fitting lenses increase colored contact lenses risks by scratching the eye’s surface. These injuries make the eye more vulnerable to bacteria and increase the likelihood of eye infection from contacts. A prescription for costume contacts ensures proper fit and reduces avoidable complications.
Why Proper Contact Lens Fitting Matters
Proper fitting plays a major role in costume contact lenses safety. Lenses that fit correctly allow oxygen to reach the cornea and reduce friction during blinking.
Ill-fitting lenses, especially contact lenses without prescription approval, can lead to corneal abrasions and ulcers. These injuries are often the starting point for severe eye infection from contacts, underscoring the importance of wearing FDA approved contact lenses only.
Take Good Care of Those Lenses Once You Get Them
After you’ve found a trustworthy vendor and purchased contacts that fit your prescription, it’s essential to take proper care of them and use them as directed so that your risk of eye infection is as low as possible. Here are a few tips to follow:
Thoroughly wash your hands before inserting or removing contact lenses.
Touch or rub your eyes as little as you can while the contacts are in.
Never clean your contacts with any substance besides fresh contact lens solution.
(That means no water and DEFINITELY no saliva! Oral bacteria shouldn’t go anywhere near your eyes!)
We’ll repeat part of that last one because it’s important: only clean and store contact lenses in FRESH contact lens solution. Don’t try to make your solution last longer by reusing it.
Carefully read the instructions that come with your lenses.
Don’t wear them longer than the instructions recommend, and replace them as often as the instructions say to.
Make sure to take your contacts out before falling asleep! This is a good idea with any contact lenses, but especially large scleral lenses that cover the whites of the eyes. Your eyes need to breathe!
Also important for scleral lenses, make sure to stay hydrated and use contact-friendly eyedrops as needed.
Improper care dramatically increases colored contact lenses risks and is a leading cause of eye infection from contacts. Following these hygiene steps is one of the most effective ways to maintain costume contact lenses safety.
When Should I See an Eye Doctor After Wearing Costume Lenses?
If you experience redness, pain, blurred vision, discharge, or light sensitivity, you should schedule an eye exam right away. These symptoms may indicate an eye infection from contacts or corneal injury.
Early treatment reduces long-term colored contact lenses risks and helps prevent permanent damage. Eye doctors can assess whether complications are related to fit, hygiene, or exposure to illegal costume contacts.
