简要总结
Computer vision syndrome also referred to as digital eye strain, describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader, and cell phone use.
It is suggested that 64-90% of computer users experience visual symptoms that may include eyestrain, headaches, ocular discomfort, dry eye, diplopia, and blurred vision either at near or when looking into the distance after prolonged computer use. Reports have noted a strong association between dry eye and CVS, with longer periods of computer work being associated with a higher prevalence of dry eye.
Dry eye during computer operation could be caused by either a reduced spontaneous blink rate, increased corneal exposure and poor environmental conditions.
Over a period of time, the dry eye leads to higher blink rates with incomplete blinking due to increased tear film instability. The instability of the precorneal tear film affects the interval between the blinks with alternating interblink periods of longer and shorter duration . This vicious cycle of altered blinking rate with component of incomplete blinking and variable interblink intervals disturbs the work efficiency and the dry eyes among computer users and also has become an important public health problem.
In this study we are trying to compare two groups in which one who gets optimized blinking and the other with a standard treatment to observe the effectiveness of optimized blinking in cases of computer vision syndrome.
