Sclera contact lenses are not your average pair of lenses. Originally used as a medical accessory to protect the cornea of your eye, they’re now considered the most popular variants of colored contacts. Cosplayers use these contacts for re-creating the dramatic, full-eye transformation of demons, aliens, possessed characters, and other supernatural beings that regular contacts just can’t replicate.
Covering both the iris and the sclera, they give the wearer an intense, otherworldly appearance that’s ideal for conventions, photoshoots, and Halloween costumes. But what exactly are they, how do they work, and most importantly, are they safe?
Sclera contact lenses are more than just a tool for transforming your eyes. The more you know about them, the more you know about wearing, caring, and using them responsibly. Here’s all you want to know:
What Are Sclera Contacts?
The main thing that differentiates Sclera contacts is their large diameter; they cover your entire eye (including the white part). For medical purposes, their design helps protect the ocular surface of your eye by acting as a sort of shield, as well as promoting healing by retaining moisture.
These lenses are primarily worn for their dramatic visual impact, thanks to their full-eye coverage. They create bold, intense transformations, often giving the wearer an entirely altered or inhuman appearance. Unlike standard contacts, they’re mostly opaque and designed purely for cosmetic effect.
Sclera Lenses or Mini-Sclera Lenses
There are two main types of Sclera Lenses:
- Full Sclera Lenses: Typically around 22mm, these lenses cover the entire visible eye, both the iris and sclera, for a complete, inhuman transformation. They can be harder to insert and take time to adjust to.
- Mini-Sclera Lenses: Slightly smaller at 15–17mm, these still extend past the iris for a dramatic effect but are easier to handle and often more comfortable for beginners.
Coverage and Visibility
Much like regular lenses, Sclera lenses are designed with a clear center to ensure you can see through them. Despite their intimidating size, their design does not obstruct your vision; However, some designs like blackout (or blind) lenses can slightly limit peripheral vision, so they’re not recommended for driving or detailed visual tasks.
Cosplay and Halloween Effects
Sclera contacts are easily one of the most popular cosplay accessories; costume fanatics use these lenses especially for characters with intense or otherworldly appearances to dress up for Halloween and cosplay conventions.
These lenses completely cover the iris and sclera, making them ideal for portraying demons, vampires, zombies, aliens, and a variety of other fictional species. Sclera lenses offer a full-eye transformation that dramatically enhances the realism and impact of a costume. Whether you're dressing up for a convention, a Halloween party, or a photoshoot, sclera lenses help bring your character to life in a bold, unforgettable way.
Use in Movies and Theater
Sclera lenses are also commonly used as an accessory during films, TV shows, and theatrical performances. Sclera lenses are frequently used to heighten the visual impact of fantasy, horror, and sci-fi characters.
Their ability to fully change the look of the eyes makes them a valuable tool in creating monsters, creatures, and supernatural beings. You’ve likely seen them in action in popular productions such as Supernatural, The Exorcist, or Underworld, where intense, full-eye effects are key to character design.
For professional makeup artists and costume designers, sclera lenses are essential for achieving cinematic-level realism.
Medical Applications (Brief Overview)
Sclera lenses nowadays are mostly known for their appearance-shifting properties. These lenses were originally medically prescribed. Used to treat advanced eye conditions such as keratoconus, dry eye syndrome, and corneal irregularities.
Unlike soft cosmetic lenses, medical scleral lenses are rigid and filled with sterile saline before insertion, creating a fluid reservoir that keeps your eyes hydrated and improves vision.
These lenses are prescribed and fitted by eye care professionals and fall under a distinct medical category regulated for therapeutic use.
Are Sclera Contacts Safe?
Yes: When Worn Correctly
Much like regular soft contacts, Sclera lenses are generally safe to use if you use them properly and responsibly. Keeping sclera lenses clean using proper contact lens solution and storing them in properly sealed containers.
They are designed for cosmetic use, but because of their large size and coverage, they must meet the same safety standards as regular prescription lenses. To wear them safely, it's essential to follow a few key guidelines:
- Purchase only from licensed and reputable sellers.
- Get professionally fitted by an eye care specialist.
- Follow recommended wearing times and hygiene practices.
When these precautions are taken, many users experience comfortable and trouble-free wear, especially for short-term use during events, photoshoots, or cosplay.
Potential Risks and Misuse
Despite their popularity, sclera contacts can be risky if misused or purchased from unreliable sources. Remember, you can not legally purchase a pair of contacts without a prescription.
Common mistakes that lead to complications include:
- Buying from unregulated costume shops or online vendors
- Sharing lenses with others
- Wearing them for extended periods without breaks
- Failing to clean or disinfect them properly
Improper use may result in eye irritation, corneal scratches, infections, or even long-term vision damage. Due to their size, sclera lenses also reduce oxygen flow to the eye more than standard lenses, making proper care and limited wear time especially important.
Are Prescriptions Required?
Yes, in the United States and many other countries, all contact lenses, including cosmetic sclera lenses, legally require a prescription. This is to ensure the lenses fit the unique shape of your eyes and do not cause harm. Getting a prescription not only protects your eye health but also helps you find the most comfortable and accurate lens size for your needs.
Fitting and Wearing Sclera Contacts
Why Professional Fitting Is Crucial
Sclera contact lenses are not one size for all; an ill-fitted lens can cause more than just discomfort; it can damage the corneal surface it is designed to protect. So always make sure to keep an updated prescription and get scleral lenses fitted by an eye-care professional who can measure your eye size and curvature.
Steps to safely insert your contact lenses:
Because of their large size, sclera lenses can be trickier to handle than regular lenses. Their diameter covers not just the iris but also the sclera (the white part of your eye), requiring extra care, precision, and hygiene during insertion. To ensure a safe and comfortable fit, follow these step-by-step instructions carefully:
- Before you open the lens package, ensure that there’s no leakage of sterile solution and the lenses are in perfect condition.
- Wash your hands thoroughly and dry them off with a lint-free towel before you handle your contacts.
- Place the lens in the palm of your hand and gently rinse it with enough lens solution.
- Use the padding of your fingertips to lift your contact lens in an upright position, ensuring your lenses aren’t inside out.
- Use your non-dominant hand to hold your bottom eyelid, and look up at the ceiling as you insert your contacts.
- Then blink a few times and let your lenses align in the center.
How Long Can You Wear Them?
It depends on the condition of your eyes and the type of lens you’re wearing. It is generally recommended to limit wearing time to 8-10 hours, although you might want to reduce the time if you’re new to sclera lenses.
Never sleep in them or wear them continuously through an event without using rewetting eye drops.

With a wide range of colors and designs available, you can match nearly any character or creature, from demonic to alien to undead. For those aiming to make a dramatic statement, sclera lenses are the ultimate finishing touch.

Additionally, discuss with your optometrist about any underlying issues that can cause further problems.
