9. Tired eyes/difficulty focusing
Everyone experiences tiredness in their eyes from time to time, just from general fatigue and day to day living, however, a long standing issue with your eyes having trouble focusing could be a sign that you need to go and get them checked. Common activities such as using a computer, watching TV or going for a drive shouldn’t create symptoms of tiredness or trouble with your focus and if you do notice anything when doing these activities then you may be in need of a pair of spectacles!
