看电视是一种休息、消遣和娱乐,但其中是有学问的。首先是坐的位置,距离屏幕太近,电视扫描线及闪光清晰可见,但对视力造成过重负担,妨碍收看;如果离荧光屏太远,要看清图像的各个部分,不得不加大视力的紧张程度。那么,坐在多远的地方为宜呢?这取决于荧光屏的大小。荧光屏对角线为67厘米的彩色,坐在相距2.5米处比较舒服;而31和32厘米的小电视,合适距离为1米左右。
Watching television is a kind of rest, recreation and entertainment, but it is learned. The first is the sitting position, too close to the screen, the TV scanning lines and flash can be clearly seen, but the vision caused by excessive burden, hinder the viewing; too far from the screen to see all parts of the image, had to increase vision Tension. So how far should I sit? It depends on the size of the screen. Screen diagonal 67 cm color, sitting 2.5 meters away from the more comfortable; and 31 and 32 cm small TV, the appropriate distance of about 1 meter.
