Description for Mares Opera Mask:The unique, elegant styling and low internal volume make the Opera a beautiful and distinctive mask, ideal for all underwater activities.
Constructed using the most up-to-date technology, its ergonomic shape adapts to virtually any face thanks to the soft hypo-allergenic silicone skirt, with a lip seal that adheres perfectly to the skin. The Opera has symmetrical glass panels to facilitate the application of corrective lenses. In fact, it is possible to exchange the left and right lenses without altering their focal points. Thanks to the special optical system, the desired corrective lenses can be easily applied in minutes. A complete range of diopter strengths is available, from -1 to -10, in .5 increments.
The lenses are made of tempered glass according to strict international directives (ANSI - DIN).
