There are many causes of a chronic red eye ranging from an infection to simple dryness. The first thing you need to do is have your refraction
done to make sure there is no need for a spectacle prescription as an exertion of the eye muscles can lead to fatigue
at the end of the day. Redness and tiredness
is quite often fixed with a course of lubricating eye drops used frequently for a few weeks. If you have an inflammation of the upper lids avoid using any eye make up for a while if you do and add an eyelid cleaning ritual with a warm water and soapy solution ( baby shampoo) twice a day to clear any blepharitis
or lid infection. Using a mild antibiotic eye ointment at bedtime can help. Try this for a few days and the symptoms should subside.
