The Topcon EZ-200 Advance is the most sophisticated spectacle and lenses measuring system is also the easiest to use.


The EZ-200 Advance allows the user to do an accurate measurement in only three steps:
1. insert glasses,
2. push the measurement button

3. obtain measurement results.


The Topcon EZ-200 Advance employs a Hartmann Shack sensor. Through the Hartmann Shack plate, the entire lens area can be scanned at once. Compared to manual alignment with a conventional lens meter, this improved method is faster and more efficient. Automatic sensing over a wider measuring area reduces the chance of missing measurement points and provides repeatable measurements that are not dependent on the operator’s skill.
