Dry eye glasses sizing guide

Size guide for moisture chamber glasses

We have categorised the different models as Small, Small to Medium, Medium, and Medium to Large.

These labels are for your guidance only to help you narrow down the selection of eyewear that may suit your needs.

They are based on a combination of factors including the size of the frame and lenses, the curvature of the eye cup and our experience of fitting these glasses to customers.

Also on the the description of each pair of 7eye Airshield and Ziena glasses we have listed the approximate dimensions of each frame.

If you're in doubt about which size to order, we recommend buying two different models for comparison and then returning the one that fits less well.


A note on the Marina, although it has the widest fit in the Ziena eyewear range, it can actually be the best fit for Small to Medium and Medium faces. This is because the eye cup shape is based on the latest research and development into cranial anatomy, enabling the Marina to be one of the most versatile frame in the Ziena range.
