1. Prescription
PWR from a current contact lens prescription, not a glasses prescription. Plano still requires a fit check.
2. Base curve
Match your current lenses. This is the number that decides comfort.
3. Diameter and graphic diameter
Stay within about 0.3 mm of your natural fit, and choose the printed area for the look.
4. Market clearance
Confirm the product is cleared for sale in your country and carries the required marking.
5. Replacement cycle
Daily if you wear occasionally, monthly if you wear regularly and will clean properly.
6. Stock and expiry
Check the batch date and that the power you need is in stock, not backordered.
7. Shipping and customs
Know the delivery window and who pays import duty. A cheap lens with a four-week transit is not cheap.
8. Returns
Confirm the policy covers unopened boxes and what happens with a fit problem.
9. Spares
Order one extra pair. The most common regret is a torn lens the day before an event.
Frequently Asked Questions
What is the single most important check?
Base curve. A lens with the wrong curve will not be worn.
Should I buy a year of lenses at once?
No. Buy one cycle first and confirm the fit before committing.
Do I need a prescription for plano lenses?
In the US, yes. Elsewhere the rules vary but a fit check still matters.
