## CL-2 Description
This app handles the oblique axis formula automatically — combining the residual refraction with the lens in situ using vector cylinder addition. No matter how much the astigmatism has shifted, you get the correct new contact lens parameters instantly. Built for practitioners who need accuracy, not approximations. 
- Switch instantly between a clean light interface and a deep dark theme. Optimized for every lighting condition, whether you're in a bright showroom or a dimly lit consulting room. 
- Export the current patient card as a high-quality image and share it instantly — via message, email, or any app on your device.
