Do not round or convert a contact lens power on your own. Order the exact contact lens specification prescribed for the exact model, or ask the prescriber what to do when the storefront does not offer it. This guide keeps the visual decision separate from the product, prescription and quantity checks that determine whether an order is appropriate.

Direct answer
Do not round or convert a contact lens power on your own. Order the exact contact lens specification prescribed for the exact model, or ask the prescriber what to do when the storefront does not offer it.
Evidence to compare
A contact lens prescription can include more than sphere: brand or model, base curve, diameter, cylinder and axis may all matter. A nearby menu value is not automatically an equivalent choice.
| Checkpoint | Useful evidence | Do not assume |
|---|---|---|
| Exact product | Brand, model, color and schedule | A related name is identical |
| Order eligibility | Complete live options for each eye | A headline range proves availability |
| Appearance | Comparable on-eye images | One edited photo predicts every result |
| Final order | Cart lines, quantities and timing | Remembered values are automatically correct |
A practical workflow
Read the prescription one eye at a time, preserve plus and minus signs, and compare every required field with the product selector. Pause when any field is missing instead of choosing the closest value.
- Open the exact product page rather than relying on a collection card.
- Confirm product identity, schedule and pieces per box.
- Check every required option separately for the left and right eye.
- Compare only the candidates that remain valid.
- Read the completed cart before payment.
Mistakes to avoid
Eyeglass numbers should not be copied into a contact lens order without a valid contact lens prescription. KPOP2 should clarify menu or package information, while prescribing decisions belong to an eye-care professional.
Store content can explain what a product page, selector or package says. It should not diagnose symptoms, choose a lens for an eye or invent equivalence between products. If anything about the prescription or fitted model is unclear, pause and ask the eye-care professional.
