Bausch + Lomb Lacelle Crystal Brown: Daily 30p vs Monthly 6p
Lacelle Crystal Brown Daily 30p and Monthly 6p share a current 12.7 mm graphic-diameter field, but they use different replacement systems and overall diameters. Choose the exact prescribed version before comparing routine, box count or price. The most reliable decision keeps appearance, product identity, order eligibility and timing as separate checks until the final cart review.

Direct answer
Lacelle Crystal Brown Daily 30p and Monthly 6p share a current 12.7 mm graphic-diameter field, but they use different replacement systems and overall diameters. Choose the exact prescribed version before comparing routine, box count or price.
Evidence worth comparing
The daily listing contains thirty individual lenses and the monthly listing contains six. A shared color, base curve or graphic field does not make the products interchangeable.
| Checkpoint | Useful evidence | Avoid assuming |
|---|---|---|
| Identity | Full model, shade and schedule | A related name is identical |
| Appearance | Comparable light and starting iris | One edited image predicts every result |
| Eligibility | Complete live options for each eye | A headline range proves availability |
| Order | Cart lines, quantities and dated status | A label alone proves the final outcome |
A practical comparison method
Confirm the exact version, calculate supply separately for each eye and compare exact-version appearance without transferring care instructions between schedules.
- Open the exact product or support page instead of relying on a search snippet.
- Record product identity, version, package unit and the condition being compared.
- Change one important variable at a time and remove unlike evidence.
- Confirm the complete left- and right-eye requirements without rounding or substitution.
- Read the final cart, preparation note and delivery information before payment.
Turn the evidence into a decision
Do not clean a daily lens for reuse or count a monthly replacement period only by the days it was worn.
Store content can explain product fields and ordering steps, but it does not prescribe, fit, round, convert or substitute a contact lens. Remove lenses and seek appropriate professional advice if pain, marked redness, discharge, light sensitivity or persistent blur occurs.
