Examination are carried out on 64 school children Ist class from school "104", town of Sofia where computer training on mathematics and mother tongue is introduced in the frames of pedagogic experiment. The studies are performed parallelly at traditional and computer lessons, realized in two variants (with one and two school hours daily). In order to establish the functional status of the visual analyzer during computer training the following methods are used: studying the distance of the nearest point for clear vision (punctum proximum), stability of clear vision, threshold of the electric eye sensitivity, critical frequency of fusing of the light flickerings. A full preliminary ophthalmological examination is made by "Vision test", as well as chronometric control of each student to establish the real time of work with computers. Taken into consideration are also the data for illumination of the working places in the computer studies and class rooms where the traditional school hours are held. The analysis of the data received shows that the computer training (1 and 2 computer lessons daily) with schoolchildren, Ist class, has no unfavourable effect on the functional status of the visual analyzer in the limits of study hours up to 25 minutes.
对索非亚市“104”学校一年级的64名学童进行了检查，该校在教学实验框架内引入了数学和母语的计算机培训。研究在传统课程和计算机课程中同时进行，分为两种变体（每天1节和2节学校课时）。为了确定计算机培训期间视觉分析器的功能状态，使用了以下方法：研究明视最远距离（近点）、明视稳定性、电眼敏感度阈值、光闪烁融合临界频率。通过“视力测试”进行全面的初步眼科检查，并对每个学生进行计时控制，以确定使用计算机的实际时间。还考虑了计算机学习场所和进行传统学校课时的教室的照明数据。所获得数据的分析表明，一年级学童每天进行1节和2节计算机课程的培训，在长达25分钟的学习时间范围内，对视觉分析器的功能状态没有不利影响。
