基于双向光干预技术的爽目电脑护眼仪

Computer Eye SPA Based on Bidirectional Optical Interference Technology

针对长时间使用电脑造成的视疲劳问题,研制出了爽目电脑护眼仪.该护眼仪采用双向光干预技术,其中,纵向光采用8 000K色温的仿自然光光源,横向光通过特殊设计的护眼色谱卡后变为波段为550~700nm的组合光谱.对比爽目电脑护眼仪使用前后的效果,使用后被试者的主观评价更好、满意程度更高,客观试验结果表明,闪光临界融合频率和眨眼次数在使用该护眼仪后得到了明显增加,经统计学t检验处理,差异具有显著性(P<0.01).由此可知该爽目电脑护眼仪通过调整外部视觉光环境有效缓解了电脑视疲劳.

To solve the problem of computer visual fatigue caused by the prolonged use of computers, a computer eye SPA was developed. The computer eye SPA applies the technology of bidirectional optical interference. The vertical light imitates natural light source of 8 000 K temperature, the transverse light absorbs the light of other bands via a eye protection spectrum card developed by a special designed micro- nano-sized material and only reflect a combination spectrum ranged in 550 - 700 nm. The research indicates that the subjective evaluation and the degree of satisfaction are better compared users with non- users. Objective experimental results show that the number of critical flicker fusion and blinking frequency have increased after using the computer eye he concluded that the computer eye SPA can adjust computer visual fatigue. SPA, the different is significant（P^O. 01）. It can the external visual optical environment to relieve
