It’s not a good idea. Blepharitis is an eye condition that causes the eyelids to become chronically irritated. There are two forms of blepharitis — anterior and posterior. Anterior blepharitis affects the outside of the lids, where lashes are located. The posterior form of blepharitis affects the inner eyelid and is caused by a disorder of the oil glands within. In both forms of blepharitis, symptoms include general irritation, flaking of the eyelid skin, redness and dry-eye sensations. Therefore, this condition may affect your ability to wear contact lenses.
