Tranquileyes Chronic Dry Eyes Therapy with ThermoEyes provides soothing relief from chronic dry eyes. Used with warm water, tanquileyes create heat to help stimulate tear production. Increased humidity helps prevent the evaporation of natural and artificial tears, bathing the cornea in moisture, relieving dry, tired eyes. The moist heat treatment is further enhanced by using the thermoeyes reusable heat packs which provide an extra heat source to boost and prolong the benefits of the original treatment. Use daily 30–45 minutes or during sleep.
