If you have never tried our eyewear before, follow the steps below to ensure maximum success to fitting.

The goal is to seal completely around the eyes. It is not as much as referencing the frame size (e.g. the large frame for a large face or a small frame for a small face), but rather focusing on the curvature of the frame to seal around the curvature of your brow bone and cheekbone.

  1. Give us a call - If you’ve never worn our frames before, allow us to help you select the styles! 909-509-8228. We can help narrow down the selections especially if you can provide us with pictures that include both front view and side view of your face by text or email.
  2. Try many styles - Try as many frames as you can to find the best fit. This is not typical eyewear as we have to gauge the curvature of the frame to the curvature of your face, which is not quite quantifiable. So best way to know what seals is to simply try as many styles as possible.
  3. Where to find glasses to try? First check out the vendor locator on top of the web page. If there is no store near you, you can either do the 10 Day Trial program or purchase the glasses directly from us to try.
  4. Get the Ear Gripper – Between 60-70% of our users are recommended to use a leash or ear gripper to tighten the seal. It’s amazing how such a simple contraption can make a world of difference to the fitting! Trust us on this! - Check out the Ziena Ear Gripper How To Video to learn more.
  5. Find a buddy - When you receive the glasses, have someone in front of you check the seal above, below, and around the side of your eyes. Sometimes the silicone is so soft that you don’t notice it’s sealed already.
  6. Fogging issue? It is ok to have a little bit of gap about ¼th of your finger because to have too perfect of a seal would not allow your perspiration to escape and therefore have higher chance to fog the lens. (Medical providers will need at least 99% seal however).
