Rating scale	Description
1	Working environment is too dark and difficult to accept (it is difficult to see the screen display)
2	Working environment is too dark, but it is acceptable (you can see the screen display)
3	Working environment is comfortable and you like it (screen display content can be clearly seen, and it is not easy to fatigue when working a long time)
4	Working environment is too bright, but it is acceptable (screen display content can be clearly seen, and the eyes are prone to discomfort for long-time working)
5	Working environment is too bright, or even glaring (screen display content can be clearly seen, and the eyes are prone to extreme discomfort for long-time working)
