## Lens Manufacturing Process
To ensure the highest quality, our lenses undergo:
1. Attachment of suction to the focal point before inserting into the 3D stereoscopic design equipment.
2. PD, OH, and bevel setting before 3D processing.
3. 3D stereoscopic processing with specialized equipment.
4. Manual finishing to prevent distortion and to trim sharp edges.
After lens processing:
1. Insert the lens into the frame and check the balance on both sides.
2. Fit the glasses for comfort, suitable for more than 90% of Koreans.
