In lens manufacturing, a re-do means the lab remakes a lens instead of shipping the first version. This happens when the lens fails inspection or does not match the order. A re-do can be caused by a coating flaw, a scratch, or a surfacing issue. The lab then rebuilds the lens to meet the correct specs.
read more about re-do (lens) ...A re-do can start with a wrong lens power, the wrong base curve, or an axis error on astigmatism orders. Cosmetic issues like scratches, edge chips, or coating haze can also trigger a remake. Some re-dos happen when the frame fit changes and the lens needs a new cut. The lab documents the reason and starts the remake process.
Labs check lens power, prism, and axis with verification tools before shipping. Coatings get inspected for haze, bubbles, or uneven tint. Many labs also run final checks for lens markings and edge quality. If something looks off, the order gets flagged for a remake.
A re-do usually adds extra lab time because the lens has to be rebuilt and inspected again. Shipping time stays the same once the remake leaves the lab. The updated timeline depends on lens type, coatings, and lab workload. Retailers can share the new ship date after the lab updates the order.
Accurate Rx entry helps, including CYL, axis, and any prism notes. PD and fitting height measurements matter a lot for progressives and bifocals. Frame adjustments before ordering can help the lens sit in the right spot. If something feels wrong after delivery, a fit check can confirm if a remake is needed.
Not always. Many re-dos happen from a lab defect like a scratch or coating flaw. A wrong Rx entry can also trigger a remake, so order details are worth double-checking.
A re-do can add a few extra business days, sometimes longer for specialty coatings or high prescriptions. The retailer can share the updated lab estimate once the remake starts.
Yes. If anti-reflective coating looks hazy, patchy, or has bubbles, the lab may remake the lens. Tint and photochromic issues can also lead to a redo.
Ask the retailer for the updated timeline and the reason code if available. Confirm the Rx values and measurements that were submitted. Keep the order number handy for faster updates.
