55. As for some people, house dust, mold and mildew, cat dander, smoke and much more are the allergic source for eyes. In addition, some people have a mild or strong adverse reaction to particular substances, such as cleaning chemicals. Here I want to say that eye allergies cause dry eyes easily. Dry eye syndrome is a very common condition that is characterized by a disturbance of the tear film. Some eye drops and substances get into the tear film easily. So if your eyes are allergic, please avoid Vaseline, mineral oil, and lanolin, including antibiotic eye ointments and get far away of sleep masks that no need to wash. You also should far from aromatic oils and incense. If you really feel uncomfortable, you can use soda solutions to wash your eyelids and face. After that, discuss with your eye doctor and find out the real causes of your allergies. Don't take any medical treatments by yourself, or you just worsen your condition.
