To relieve itchiness and irritation around the eyes, one may apply an over-the-counter hydrocortisone cream for a few days. Itchiness from rashes can also be relieved by applying a cold pack or cucumber slices on the eyes.
Avoid touching or rubbing the area with your hands, as this might intensify symptoms.
Finally, if these measures do not relieve your rash around the eyes after a few days, consult a dermatologist or medical doctor who may evaluate the cause of your symptoms and prescribe appropriate medications.
