Make sure to have your eyes looked at regularly. Many people, particularly if they do not wear glasses or contacts, have not been to the eye doctor in years. You should go at least once in your 20s and at least twice in your 30s to make sure everything is on track. Once you hit forty, try and visit the eye doctor every three years or so. And, when you reach age 65, you should go every other year.
Do you wear contacts? If so, make sure you have a pair of glasses that you can wear if your eyes get irritated. You do not want to make the situation worse by forcing yourself to wear the contacts because serious problems can result. Also, make sure you keep the contacts very clean.
