Are Coloured Contact Lenses Safe? What Eye Experts Want You to Know
Coloured contact lenses are a fun and stylish way to enhance your natural eye color or even completely change your look for a special event or everyday wear. From subtle enhancements to dramatic transformations, these lenses have become increasingly popular, especially among beauty enthusiasts, influencers, and costume lovers. But with their rising popularity comes a crucial question: Are coloured contact lenses safe?
In this article, we’ll dive into what eye experts have to say about the safety of coloured lenses, how to wear them responsibly, and what risks you should be aware of before popping in a pair. Whether you’re considering green contact lenses or vibrant violet hues, understanding the facts can help you make informed decisions about your eye health.
What Are Coloured Contact Lenses?
Coloured contact lenses are cosmetic lenses that alter the appearance of your eyes. They come in a variety of shades and styles — from natural colors like brown, blue, and green to more theatrical or fantasy designs used in film or cosplay. These lenses can be prescription-based for vision correction or non-prescription (plano) for cosmetic purposes only.
There are generally three types of coloured contact lenses:
1. Visibility Tint
These have a faint tint added to help you see the lens better during handling. They don’t affect your eye color.
2. Enhancement Tint
Designed to deepen and intensify your natural eye color. Best suited for people with lighter eyes.
3. Opaque Tint
Completely changes the color of your eyes. Ideal for dramatic transformations and darker eyes.
Are Coloured Contact Lenses Safe?
The short answer is yes, coloured contact lenses can be safe—but only when used properly. According to eye health professionals, the safety of these lenses depends entirely on how they’re purchased, fitted, and maintained.
What Eye Experts Say
The American Academy of Ophthalmology (AAO) and optometrists worldwide agree that coloured contact lenses are medical devices — just like regular contact lenses. They require a valid prescription, even if you don’t need vision correction. This is because lenses that don’t fit properly or are made from poor materials can cause serious eye problems.
Let’s break down what the experts highlight when it comes to safety:
Common Risks of Improper Use
Wearing coloured contact lenses without proper precautions can lead to several complications, including:
1. Eye Infections
Using lenses without cleaning them correctly or sharing them with others can lead to bacterial or fungal infections like keratitis, which may require intensive treatment.
2. Corneal Abrasions
Lenses that don’t fit well or are inserted incorrectly can scratch the surface of your eye, causing pain, blurred vision, or even permanent damage.
3. Reduced Oxygen Supply
Some low-quality cosmetic lenses don’t allow enough oxygen to reach the cornea, leading to dry eyes, irritation, and long-term health concerns.
4. Allergic Reactions
Some individuals may have sensitivities to the dyes or materials used in coloured contacts.
How to Wear Coloured Contact Lenses Safely
To reduce your risk of complications, here’s what eye care professionals recommend:
1. Get a Prescription from a Licensed Eye Doctor
Even if you’re only interested in wearing lenses for aesthetic purposes, always schedule an eye exam. Your doctor will ensure the lenses fit properly and won’t damage your eyes.
2. Never Buy from Unverified Sources
Avoid purchasing coloured lenses from beauty stores, costume shops, or online sellers without credentials. Always buy from reputable retailers that require a prescription. You can find a list of trusted sellers [here].
3. Follow Proper Hygiene
- Always wash your hands before handling lenses.
- Use a sterile solution to clean and store them.
- Never use tap water or saliva to clean contacts.
4. Replace as Recommended
Don’t try to extend the life of your lenses. Follow the manufacturer’s or doctor’s guidance on when to replace them, whether daily, weekly, or monthly.
5. Avoid Sleeping with Lenses In
Unless your lenses are specifically designed for overnight use, remove them before sleeping to allow your eyes to breathe and recover.
What to Consider When Choosing Coloured Contacts
When selecting coloured contact lenses, consider the following:
✅ Material and Breathability
Look for lenses made from silicone hydrogel or other oxygen-permeable materials.
✅ Brand Reputation
Stick with FDA-approved brands or ones recommended by your optometrist.
✅ Color and Purpose
If you’re going for a natural look, enhancement tints or green contact lenses might be ideal. For bold looks, opaque tints work best.
Green Contact Lenses: Popular Yet Safe?
Green is one of the most sought-after colors when it comes to eye enhancement. Green contact lenses offer a natural yet captivating effect, especially for people with lighter eye colors. But remember, popularity doesn’t guarantee safety.
Just like any other colored lens, it’s crucial to choose green contact lenses from a reputable brand and follow all usage guidelines. Never wear them longer than recommended, and consult your eye doctor if you experience any discomfort or vision changes.
Can You Share Coloured Contact Lenses?
Absolutely not. This is a major red flag among eye experts. Sharing lenses can transmit harmful bacteria and viruses, leading to severe infections. Even if someone has the same prescription, each person’s eyes are different in shape and moisture level. What fits one eye may damage another.
Final Thoughts: Safety First, Style Second
Coloured contact lenses can be a safe and stunning way to express your personality—when used responsibly. From dramatic costume looks to subtle everyday changes like green contact lenses, the key lies in buying the right lenses, using them properly, and listening to your eyes.
Remember, your vision is precious. No aesthetic trend is worth risking your eye health. Always consult an eye care professional before starting to use any type of contact lenses, cosmetic or not.
