When we look at an image, the eyes focus on it and the light rays enter the eyes through the iris; this is then focused on the cornea or lens of the eye. The image formed is then transmitted to the brain, which tells us what we are seeing. All this activity needs the coordination of both the structures of the eyes and their muscles. When we look at objects like a computer or phone screen the eyes and the muscles around the eyes are worked excessively as they are trying to adjust to the light that is emitted from the screen. This constant adjustment to quickly changing images or text is what causes the structures within the eye to get strained.
