Normally your eyes produce enough natural tears to help them move easily and comfortably and to remove dust and other particles. If they do not produce enough tears, they can become dry, red, and painful. Dry eyes can be caused by wind, sun, heating, computer use, and some medications. Hyaluronate Eye Drop keeps your eyes lubricated and can relieve any dryness and pain. This medicine is safe to use with few side effects. If you wear soft contact lenses, you should remove them before applying the drops.
