Probably cultivate students to read and write posture, and outstanding habits, books and eyes should adhere to a city rule. Campus desks and chairs should be suitable for students to teach students to write, not too small, not too close, not to write oblique, grass characters. Don't write too long. Write and read with good light, the best light from the left. And it is to maintain the light color of both eyes, do not read, write in too dark perhaps too bright light, reduce student burden, make sure class break 10 minutes rest, reduce eyesight exhaustion. Actively carry out physical exercise, careful eye exercises.
Use the class desk and chair that regular manufacturer produces, correct sitting position, the close design of my factory stylist, still set adjustable height for each set of class desk and chair, better let student comfortable study
