Product description
Properties
Medical aid that diffuses latent heat to release the Meibomian glands to improve the well-being of the eyes and eyelids. Blephasteam relieves symptoms associated with Meibom gland dysfunction. The dysfunction causes a number of eye irritations, such as dry eye syndrome. The heat and moisture generated inside the glasses melt the secretions in the clogged glands, making it easier to release them through pressure and massage.
