Stella Adjustment Instructions

Stella TheraSpecs are easy to adjust for a perfect fit using some heat from your hair dryer. You can adjust them at either the nose bridge or arms.

Nose Bridge Adjustment

For a frame that feels too narrow or too wide, adjusting the nosepiece will get the fastest results:

Start by aiming your hair dryer at the part of the frame you'd like to adjust. Frequently rotate the frame, heating the plastic front and back.
After heating for ~90 seconds, the frame should be warm to the touch but not uncomfortable to hold.
While still warm, adjust the frame. Apply even pressure, slightly over-bend the plastic to the desired position, and hold for ~30 seconds.
Quickly cool the frame under cold tap water or in front of a fan to help the adjustment set.

To refine the fit, you can use heat to adjust the arms, too.

Once you have the shape you want, cool the frame quickly under cold tap water or in front of a fan to set the adjustment.
