32ºN lenses include a liquid crystal layer that can dynamically change its optical power. When it’s off, it’s completely transparent, and you can see well to far distance, just like you would with conventional sunglasses.

When you swipe to turn it on, it’s switches to your desired reading magnification power.

The programmable and flexible reading magnification power allow full control on the reading magnification power that will be applied when you swipe your glasses. 

The initial reading magnification power is determined in a simple setup process of your sunglasses, using 32°N's dedicated phone app. You can always update the reading magnification power.
