The human eye is an extraordinary organ, constantly adapting, focusing, and protecting itself from the myriad challenges of the environment. Integral to this intricate defense system are natural tears – a complex blend of water, oils, and mucus that perform vital functions. They lubricate the eye’s surface, wash away irritants, and even deliver essential nutrients, ensuring clear vision and comfort.
