How to measure your face to see if this mask fit you.

If you look in the description there is a face seal size. You would need to measure the width and height of your face. Width is from one (outer) corner of the eye to the order corner and the height is from the eyebrow to under the nose

Pre-made Rx lens is tempered for safety, and will be installed on the mask in our studio.
