Of this form they will be able to be used with greater comfort. He is recommendable to use the solar light the greater possible time, reason why one is due to avoid that the tower in which is the CPU prevents the passage from her. The best thing is to place the computer near a window so that the solar light arrives to him from a flank, without it interrupts it to nothing to be able to take advantage of it better, and to avoid to create shades on the keyboard. However, we will have to place the monitor in a position which the solar rays cannot affect envelope he, to avoid that we did not prune to see some zones of the screen.

Simplest it consists of placing a lamp, standing up provided of screen, to about two meters in front of the monitor and igniting it when it is necessary. Also the wall can be illuminated subsequent to the monitor with a lamp oriented towards the same or to place you apply murals to its back or after the monitor that illuminates the writing-desk partially.
