Blink Lubricating Eye Drops address the redness, burning, itching and sensitivity associated with occasional and chronic dry eye syndrome, which impacts up to 40 percentof Americans. Blink Eye Drops are so named because they provide relief with each and every blink of the eye. Blink Lubricating Eye Drops replenish tear film and improve tear film stability with each blink, too – that has been clinically proven. Made with natural ingredients, these lubricating eye drops can actually adapt to your specific eye needs to provide longer relief than typical eye drops. In addition, Blink Gel Tears Lubricating Eye Drops have a more viscous formula for additional comfort in patients with more severe cases of dry eye. These formulas can be used day or night.
