Abstract: A composition and method for applying the composition topically to an eye for improving corneal and surface hydration and reducing blue light neuro-stimulation, especially during the several hours preceding sleep. In one embodiment, the composition combines an artificial tear with fluorescein sodium. The artificial tear may include carboxymehylcellulose sodium, polyvinyl alcohol, hydroxypropyl cellulose and glycerin. In another embodiment, the composition comprises synthetic human melanin combined with fluorescein sodium in an aqueous solution to reduce ocular UV light and HEV light exposure.
