Styes and dry eyes respond well to essentially "melting" the hardened "buttery" substance that is blocking the glands from releasing natural oils that help lubricate the friction of your blinking, coat the eye surface, and promote longer tear "stay" (tears don't evaporate as fast) improving dry eye symptoms naturally and holistically.  It is suggest to have your eye lid glands evaluated with "meibography" to check for deep chronic clogged glands that can be causing your dry eyes first.  Lipiflow, or tearcare may be prescribed before you use this product.
