Will electrooculography be used to track my eye movements during a computer study?

I am 30 and doing a test to see how people read a computer screen. Will they use eclectrooculography? Is this harmful
In electrooculography (EOG) electrodes are placed on your skin near your eyes and it measures changes in resting potential between the eyes as they move. For example, if the right eye is moved to the right, the electrode on that side notes that positive movement and the opposite electrode sees the negative aspect of this eye movement. This results in a potential difference between the two electrodes. Thus, this recorded potential change is a measure of eye movement. There are various different uses of EOGs and your physician can help describe its use in your specific situation. Since EOGs can be used to detect eye movements, it is possible that it could be used during your test to track how quickly your eyes move when a new stimulus is shown. To get the full details in what your exact test will entail, you should speak your physician that will be conducting the computer screen test. An EOG is also useful in assessing the function of the ocular pigment epithelium. It can be used to measure the difference in potential between light and dark environments. EOGs have been used to help gamers improve their playing speed. They are also a part of a full night polysomnography (sleep study). You should follow up with your primary care physician to discuss your specific test, electrooculography, its uses, benefits, and disadvantages. An ophthalmologist can be consulted if you have any ocular or vision concerns.
