The EyeLocc™ is made from a highly flexible material. This makes it much easier for the dressing to conform completely to the eye socket and forming a complete seal around the eye. When the eye is completely sealed from the outside, it retains its moisture better and is also protected from outside harm such as chemicals and objects.
The white border around the outside of the dressing provides it with a more rigid, and easier to handle backing material. This border ensures that while you can see the eye through the clear window in the middle, you also have a reliable border that makes sure the dressing does not fold or bend while applying the dressing.
