What is the quickest way to get rid of eye strain?

Hello Guys,

​

Is there any quick and easy method that I can use to get rid of eye strain immediately or do I have to refrain from using any digital devices for at least a week? I have been on annual leave for the past three days and so far I have barely used any digital devices. However, I still feel an awful pain in my right eye and sometimes on my left as well. I was wondering what it would take to get rid of it, and how long would that take? I am thinking that I should spend a week off work without using anything digital?

​

Thanks in advance guys!
