Computer Eye SPA Based on Bidirectional Optical Interference Technology
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 SPA, the different is significant(P<0.01). It can be concluded that the computer eye SPA can adjust the external visual optical environment to relieve computer visual fatigue.
