FAQ

Is the price for one lens or for the pair?

It's for a complete pair made with the data for both eyes.

What if I don't understand some of the data?

Write to us with any questions before buying, or give us the details exactly as they appear on your prescription: we will check the configuration before starting production.

What's the difference between the indexes?

1.50 is the standard option. Higher indexes reduce thickness for strong prescriptions; their availability depends on the finish.
