1. Check that the device is cleared for your market
In the US, contact lenses - including plano cosmetic lenses - are Class II medical devices. In the EU and UK they carry CE or UKCA marking. In Japan they must be PMDA approved. If a store cannot tell you which regime its lenses are cleared under, that is the first red flag.
2. Know your prescription, even for plano
Plano (0.00) lenses do not correct vision, but your base curve still has to suit your eye. If you have never worn lenses, a fitting with an eye care professional removes most of the risk and tells you the BC range that works for you.
3. Compare specification, not marketing copy
Four numbers decide whether a lens is comfortable and how it looks: DIA (overall size), graphic diameter (printed area), base curve, and water content. A 14.2 mm lens with a 13.6 mm graphic looks completely different from a 14.5 mm lens with a 13.8 mm graphic, even though both are called 'natural'.
4. Read the return policy before you pay
Cosmetic lenses are hygiene products, so opened boxes are rarely returnable - that is normal. What should be clear is what happens with unopened boxes, damaged deliveries and wrong prescriptions. A store with no visible return page is a store that will be hard to deal with later.
5. Check shipping time and duties
A three-week delivery turns an impulse purchase into a refund request. Look for a stated dispatch time and a delivery window per country, and check whether import duties are included. Lensora publishes both per market.
6. Buy one pair before buying five
Colour on a screen is not colour on your eye. Order a single pair, wear it in daylight and indoors, then decide. This is the single biggest mistake first-time buyers make.
7. Keep the packaging until you are sure
Batch numbers and expiry dates live on the box. If a lens feels wrong, you need that information. Store lenses at room temperature, away from direct sun, and never use a lens past its expiry.
Frequently Asked Questions
Can I buy coloured contacts without a prescription in the US?
No. Plano cosmetic lenses are still regulated Class II devices and require a prescription.
How long should delivery take?
Domestic 3-7 business days and international 7-15 business days is a normal range for a specialist retailer.
What if the colour looks different from the photo?
Expect variation: iris colour, lighting and pupil size all change the result. That is why buying one pair first is the standard advice.
