Check the registration
In the US, a lawful lens carries a prescription requirement and the seller asks for it. In the EU and UK, the packaging carries a CE or UKCA mark and a manufacturer address. In Japan, it carries a 高度管理医療機器 approval number.
Look at the labelling
Cleared products print the manufacturer name, country of origin, material, water content, diameter, base curve, power, sterility method and expiry. A box that omits these is not compliant.
Seller signals
A seller that never asks for a prescription, sells at implausibly low prices, uses stolen brand photography, or ships from an unrelated category is a warning sign.
Packaging quality
Blister seals should be intact and printed cleanly. Vials with damaged foil or cloudy solution should be discarded, not used.
What to do if unsure
Ask the seller for the registration number and manufacturer. A legitimate seller answers without hesitation.
Frequently Asked Questions
Are cheap lenses always fake?
No, but price far below the market norm for a given cycle is a reason to check the registration.
Can I verify a lens myself?
Check the registration database for your market using the number printed on the box.
What if I already wore a suspicious lens?
Stop wearing it and watch for redness, pain or blurred vision. Seek care if symptoms persist.
