The eye is often said to be the gateway to the soul or the mirror of our deepest emotions. It is also a highly developed anatomical wonder that processes data instantaneously and passes it on to the brain, while expressing emotion in a way that defies all explanation. With just a glance – be it smiling, questioning, tired or lovestruck – people’s eyes can indicate their emotional state and sometimes even reveal what they are thinking. The eye is a gateway that is open in both directions.

This connection between the world outside and the world within is subject to constant strain in our visually oriented society. We receive 90% of our sensory perceptions through the eyes. This being the case, it is hardly surprising that they are occasionally reddened or dry.
