Covid, your mind probably travels straight to signs like cough or sore throat. However, there are also symptoms that won't make you want to crawl into bed with a cup of tea.
This might make it difficult to pin them down; however, knowing what to look for could help. From hay fever to spending hours in front of your computer, there are plenty of factors that could leave your eyes irritated and sore.
