i'd suggest you consult a medical professional about this. it could be something as simple as dry eyes due to the winter season but since these symptoms came on so suddenly and severely it also could be that you have developed an eye infection called conjunctivitis. until you can get this diagnosed be sure to wash and dry your hands thoroughly many times a day especially before touching your eyes. if this is conjunctivitis it's highly contagious. even if it's not pinkeye you don't want to risk spreading any possible infection to others. hope this helps!
recently both eyes sting and burn all day. extremely dry. must blink hard non stop. extreme discomfort. not too bad when i wake up in the morning. as the day goes on they get more and more dry and start to sting and burn if i do not strenuously blink. the excessive blinking causes the muscles around my eyes to become sore. have worn contacts for over 20 years with no issues. even if i do not have contacts in this occurs. started about 3 days ago. if i try not to blink eyes start to sting and burn so badly that huge amounts of tears produce. eyes have redness as well. causes? solutions?
