Coloured contact lenses have become an increasingly popular accessory for people looking to change their eye colour for aesthetic reasons, special occasions, or everyday styling. However, unlike ordinary fashion accessories, contact lenses are medical devices that come into direct contact with the eyes, and buying them requires a degree of care and awareness. This article outlines what you need to know before buy colour contact lenses in India, including types available, safety considerations, and the buying process.
Understanding Colour Contact Lenses
Colour contact lenses are designed to change or enhance the natural colour of the iris. They are broadly categorised into three types:
Visibility tints have a very light tint, usually blue or green, added only to help the wearer locate a dropped lens. They do not significantly alter eye colour.
Enhancement tints are translucent and slightly darker than visibility tints. They are meant to enhance your natural eye colour rather than change it completely, making them ideal for people with lighter-coloured eyes.
Opaque tints are the most popular for a complete colour transformation. These lenses have a solid colour pattern that can change your eye colour entirely, regardless of your natural shade, and are commonly used for looks such as grey, blue, green, or hazel eyes.
Additionally, coloured lenses are available in both prescription (corrective) and plano (zero power) forms. Plano lenses are purely cosmetic, while prescription coloured lenses combine vision correction with a colour change.
Why Professional Guidance Matters
A common misconception is that coloured contact lenses, especially the zero-power variety, are similar to any other cosmetic product and can be purchased and used without professional oversight. This is not accurate. Contact lenses, regardless of power, sit directly on the cornea and can pose risks if not fitted, cleaned, or used correctly.
An eye examination before purchase helps determine the correct lens curvature and diameter for your eyes, since these vary between individuals. Ill-fitting lenses can cause discomfort, corneal abrasion, or reduced oxygen flow to the eye. An optometrist can also check for any pre-existing eye conditions, such as dryness or allergies, that might make contact lens use unsuitable or require special precautions.
Where to Buy Colour Contact Lenses in India
In India, coloured contact lenses are available through several channels:
Optical stores and eye clinics remain the most reliable option, as they typically have qualified optometrists on hand who can measure your eyes and recommend suitable products.
Authorised online retailers and pharmacy platforms have also become a convenient option, particularly those affiliated with established lens brands. When buying online, it is advisable to choose platforms that ask for or recommend a prescription, and that clearly display batch numbers, expiry dates, and manufacturer details on the packaging.
Regardless of the channel chosen, it is important to verify that the lenses are sourced from reputed manufacturers and are not counterfeit or unregulated products, which are unfortunately common in the unorganised cosmetic lens market.
Points to Check Before Purchase
Before buying colour contact lenses, consider the following:
- Certification and authenticity: Purchase only from sellers who stock lenses from established, certified manufacturers. Avoid products with no visible batch or manufacturing information.
- Base curve and diameter: These specifications should match your eye's measurements, ideally determined during an eye check-up.
- Material: Most modern coloured lenses are made from hydrogel or silicone hydrogel, which allow varying degrees of oxygen permeability. Silicone hydrogel lenses generally offer better breathability for extended wear.
- Duration of use: Coloured lenses are commonly available as daily disposables, monthly disposables, or occasionally longer-wear options. Daily disposables are often considered more hygienic for occasional or first-time users since they eliminate the need for cleaning and storage.
- Expiry date: Always check the expiry date on the packaging, as expired lenses can harbour bacteria or lose their intended shape.
Caring for Your Lenses
Proper hygiene is essential when using coloured contact lenses. Hands should always be washed before insertion or removal. Lenses that are not daily disposables need to be stored in fresh lens solution and cleaned as per the manufacturer's instructions. Reusing old solution or wearing lenses beyond their recommended duration increases the risk of eye infections. It is also advisable to avoid sleeping while wearing lenses unless they are specifically designed for extended wear, and to remove them immediately if you experience redness, irritation, or blurred vision, followed by consultation with an eye care professional.
Conclusion
Colour contact lenses offer a convenient and effective way to experiment with a new look, but they should be approached with the same care given to any medical device. Prioritising a proper eye examination, purchasing from credible and certified sources, and following recommended hygiene practices will help ensure that the experience is both safe and satisfying. Taking these precautions allows you to enjoy the cosmetic benefits of coloured lenses without compromising your eye health.
