Natural illumination depends on the degree of reflection of daylight from the ceiling, walls, furniture. Ceilings, window openings and frames must be painted white, panels - in light gray, light beige, light salad, furniture - in light colors. The painted surface should be matte., to avoid glitter.

In classrooms, the illumination should be 300 lx when using fluorescent lamps and 150 lux under incandescent lighting.

There should be a window seat for classes. Adequate artificial lighting should be used in cloudy weather and in the evening.. The light should be soft (frosted bulb), not striking, but evenly illuminating the place of study. While writing, drawing, drawing the light source should be located in front and on the left, and when reading it can be on the right.

The distance from the eyes to the book or notebook should be at least 30-35 cm. It is approximately equal to the length of the arm from the elbow to the fingertips.. This distance does not require strong eye strain and makes it possible to sit without bending over.
