Another strategy is the usage of a screensaver to help during times the computer is left unattended. Covering the ...
The flicker of a CRT monitor can cause various symptoms in those sensitive to it such as eye strain, headaches [9] in migraine sufferers, and seizures in epileptics. [10]As the flicker is most clearly seen at the edge of our vision there is no obvious risk in using a CRT, but prolonged use can cause a sort of retinal shock where the flickering is seen even when looking away from the monitor.
ThinkVision displays are high-end computer monitors manufactured, designed and developed by IBM and Lenovo.. ThinkVision products are built using the design language of other Think devices such as the ThinkPad line of notebook computers and the ThinkCentre or ThinkStation lines of desktops.
In fact, early generations of computer displays were frequently related to eye strains and headache due to flickering, jitter and radiation.

A number of computer and smartphone applications adjust the computer video color temperature, reducing the amount of blue light emitted by the screen, particularly at night. Dry eye is a symptom that is targeted in the therapy of CVS. The use of over-the-counter artificial-tear solutions can reduce the effects of dry eye in CVS.
The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science , more specifically in the psychophysics of visual perception .
