PD (Pupilar Distance) ?

The Pupilar Distance or 'PD' is simply the distance between the center of your left pupil & the center of your right pupil. There are 3 ways to get your PD:

1. Call your Eye Doctor. Your doctor will give you a single # between 50 & 75 or two #'s (for your left and right.) If they can't give it to you, move on to step #2...

2. Call who made your glasses last. If you still can't get your PD, move on to step #3...

3. Measure your own PD. All you need is a Sharpie or dry erase marker, a mirror and a friend (optional.) CLICK HERE FOR SIMPLE INSTRUCTIONS to measure your PD yourself.

 Ziena Kai Dry-Eye Prescription Glasses 

The Ziena Kai Dry-Eye Prescription glasses have a stylish Black or Tortoise frame with a patented moisture chamber that reduces tear evaporation and increases overall comfort for dry eye patients. The silicone shields also insulate eyes from environmental triggers. The Kai is the perfect eyewear for people dealing with dry eye issues. The patented eyecups are designed to block out air and hold in soothing moisture. The 360° bendable arms allow for custom fitting adjustments.

Ziena Kai Prescription Glasses are Compatible with the most Advanced Lens Technology

Bikershades always offers the most advanced lens technology. The Kai goes great with New Generation XtrActive Transitions lenses, so the wearer can use one pair for both day and night. Customize your lenses with any of our performance coatings. We offer Anti-Reflective, Scratch Protection, Anti-Fog, and Mirror coatings.

How the Moisture Chamber works

The patented discreet silicone shield locks in moisture while blocking out dust, air, & other airborne irritants. Micro-magnets hold the shield in place for easy removal or replacement. Available in frost or black.

Ziena Kai Dry-Eye fits Small to Medium heads

The Kai will fit Small to Medium sized heads very well.  To find the right size and fit, it is important to consider the frame dimensions as well as the curvature of your eyebrow bone & cheek bone. The various facial anatomies should be considered on how the eyecup will fit around the orbit of your eyes. Our Try Before You Buy Program is a great way to find the correct fit!
