Is it safe to wear coloured contact lenses?
Coloured contact lenses can be a fun way to change your look or correct vision, but safety should come first. This post explores what coloured contact lenses are, the potential risks, and how to wear them responsibly to protect your eye health.
Introduction: colour and care go hand in hand
Coloured contact lenses are contact lenses that alter the colour of the iris or enhance your natural eye colour. They come in prescription and non-prescription varieties. Whether you choose subtle enhancement lenses or bold theatrical colours, understanding safety, hygiene, and proper fitting is essential. In this guide, we’ll cover practical tips for using coloured contact lenses safely and what to watch for in case you experience discomfort or vision changes.
Understanding coloured contact lenses
- Types and availability
- Prescription coloured contact lenses: Customised to correct refractive errors while changing eye colour. These require a fitting from an eye care professional.
- Prism or toric options: For astigmatism or keratometric needs, available with tinted colours.
- Cosmetic or fashion lenses: Readily available in many stores, but often require an eye test to ensure proper fit and safety.
How they work
Colours are achieved through tints placed in specific regions of the lens or by print patterns on the lens surface. Some tinted lenses have a clear center to maintain vision. The material and design influence comfort, oxygen permeability, and risks if not used correctly.
Legal and safety considerations in the UK
In the UK, regulation of contact lenses emphasizes eye health. It’s recommended to obtain lenses through reputable providers and, ideally, with a prescription or eye-care professional’s advice. Avoid buying unregulated or counterfeit products, which can pose significant risk.
Potential risks and warning signs
- Common risks
- Infection (keratitis) from contaminated solutions or improper handling.
- Reduced oxygen to the cornea leading to dryness or irritation.
- Allergic reactions to lens material or cleaning solutions.
- Scratches or microtrauma to the cornea or conjunctiva from ill-fitting lenses or debris.
- Corneal ulcers in rare cases, which require urgent medical attention.
Warning signs to watch for
- Red, gritty, or painful eyes.
- Blurry vision or sudden vision changes.
- Light sensitivity (photophobia) or tearing that won’t subside.
- Unusual discharge or swelling around the eyelids. If you notice any of these, remove the lenses and seek optician or medical advice promptly.
Safe practices for wearing coloured contact lenses
- Eye examination and fitting
- Have a full eye examination to determine suitability for contact lenses, especially if you plan to wear them regularly or for extended periods.
- Ensure the lenses fit properly; a professional fitting helps minimise movement issues and irritation.
Hygiene and handling
- Always wash and dry hands before handling lenses.
- Use fresh, appropriate contact lens solution; never reuse old solution.
- Do not wear lenses if you have an eye infection, irritation, or conjunctivitis.
- Do not sleep in contact lenses unless they are approved for overnight wear by an eye care professional.
- Clean and store lenses according to the manufacturer’s instructions.
Wearing duration and schedule
- Start with shorter wear times, gradually increasing as comfort allows.
- Adhere to the recommended daily wear time and replacement schedule (daily, biweekly, monthly).
- Avoid wearing lenses during activities with high risk of contamination (swimming, hot tubs) unless you have protective swimming goggles and your lenses are approved for such use.
Lens care and replacement
- Use only contact lens solutions designed for your lens type.
- Never use tap water, saliva, or homemade cleaning methods on lenses.
- Regularly replace lenses as advised; do not extend their life beyond the recommended period.
Colour choice considerations
Consider your lifestyle and comfort: some coloured lenses are designed for cosmetic use only, while prescription options can be worn daily.
Ensure the tint does not impair vision or create glare in bright light. Some fashion lenses may have opaque colouring that reduces contrast; this can be unsafe in traffic or driving.
What to do if you’re unsure
- Visit an optician for a professional assessment, even for cosmetic lenses.
- Ask about the differences between prescription and non-prescription coloured contact lenses and what is best for your eyes.
- If you experience persistent discomfort after wearing coloured contact lenses, discontinue use and consult a clinician.
Alternatives to coloured contact lenses
- Eye-safe cosmetic options such as coloured eye makeup or safe, non-contact modifications.
- Lens-colour options in a UV-protective sunglass that changes appearance when worn under fashion norms.
Final thoughts
Coloured contact lenses offer a fun way to change appearance, but safety must remain the priority. By obtaining lenses through reputable providers, ensuring proper fit, maintaining rigorous hygiene, and adhering to wear schedules, you can enjoy the look you want without compromising eye health. If in doubt, seek professional advice from an optician or eye care professional. Remember: safe practice with coloured contact lenses protects your vision now and in the long term.
