Best for: Dry eyes that are accompanied by flaking along the lids, which could be a sign of blepharitis, a dandrufflike inflammation of the eyelash follicles.
How they work: “People with blepharitis tend to overproduce oil, which can block the glands and cause tears to evaporate too rapidly,” says Christopher Gelston, an assistant professor of ophthalmology at the University of Colorado School of Medicine, in Aurora. An over-the-counter eye wash contains mild cleansing agents to dissolve oil and remove flakes (as well as irritants and allergens that can exacerbate the problem).
How to use them: Rinse or massage over the lash line once a day, typically at night (some washes come with a cup for application). If your symptoms don’t clear up after several days, see your doctor.
