How CVS Affects Vision?
Computer vision syndrome develops when the eyes follow the same path of repetitive motions for an extended duration of time. People while working at a computer eyes have to focus and refocus constantly , eyes move back and forth as they work or read and may also have to look down for information and then type. The eyes are made to respond to repetitively moving or changing images, altering focus and sending rapidly changing images to the brain, all of which put the eye muscles under tremendous strain. Things get even worse as the screen adds glare, contrast and flicker.
People tend to blink far less frequently while working at the computer which makes the eyes dry and blurs the vision. Problems can also get worsened if you have any previous eye issues, using the wrong glasses and not using the glasses when you have to.
