NOTE
1. Some people may feel blurry or distorted for the first time, but after 7-14 days of adaptation, you can easily switch vision in your office and enjoy the convenience.
2. Imagine multiple focal points existing into a convex magnified lens - that's multi focus.
3. Therefore, it is normal for there to be some distortion at the left and right sides of the lens.
4. The trick is to move your head together with your vision, not just your eyes.
5. For example, if you see a friend walking towards you, turn your head towards your friend instead of just moving your gaze.
