QZ's lens set
I bought 8 frames (exactly the same type) and all the lenses I need back to 20/20. I also asked my lens provider to cut all the lenses for me according to the frame. I learned how to change the lenses by myself. In this way, I want to minimize the cost also the focal plane change due to the change of frames.
Pop out the lenses are not hard!

Centermeter Log
I took 1~3 centimeter measurements every day using the Meow-sure Screen Distance app. For each measure, I recorded the average of 3~4 readings. In the table below, I summarized my monthly data as mean ± STD in the following table.
