What is important to us at MH Optical Labs: Lens Quality and Accuracy

As a lab that has been around since the 1940’s, we have experienced the impact of all the changes the industry has gone through. While quality of the lenses could be getting better with new design technologies, the importance of accuracy will always be the same. Quality and accuracy is our top priority and we do all of the appropriate steps to make sure that our products reflect that. Read along to learn a few of our standard quality control procedures:

1. Full automatic inspection for all lens types

MH assures RX quality by sending every single lens through our full automatic inspection station, the A&R Auto Mapper. This machine checks for defects that the human eye cannot see, such as generating and polishing errors. The Mapper also checks for prescription accuracy. This not only helps us monitor what goes out the door, but it helps us track errors within our process before it becomes more problematic.

2. Consumable and maintenance machine schedule

At MH, we follow a very strict consumable and maintenance schedule for our machines. In order for our lenses to have a flawless outcome, we need to make sure that every machine stays on task with polish, coating, diamond blades, and many other consumable changes. Staying ahead of machine maintenance is not only important for the accuracy of the lens, but it also keeps turnaround time low by avoiding breakage or machine downtime.

3. Quality Control Inspection by a QC Technician

Our final quality assurance check takes place right before each job enters our shipping department. An intensive quality and accuracy inspection takes place by a technician along with one last automated inspection through our lab management software. This double checks that all add on items are applied and the job cosmetically passes inspection.
