Remedy for a Non Centered Lens
A lens, which is on the cornea (center of your eye), will very rarely be displaced onto the white part
of the eye during wear. This, however, can occur if insertion and removal procedures are not
performed properly. To center a lens, follow either of these procedures:
a.
Close your eyelids and gently massage the lens into place through the closed lids.
OR
b.
Gently manipulate the off-centered lens onto the cornea while the eye is opened, using finger
pressure on the edge of the upper lid or lower lid.
Remedy for a Sticking Lens
If a lens sticks (stops moving) on your eye, apply a few drops of the recommended lubricating
solution. You should wait until the lens begins to move freely on the eye before removing it. If non-
movement of the lens continues, you should
IMMEDIATELY
consult your Eye Care Practitioner.
Dried Lens in Case
If exposed to air while off the eye, a soft hydrophilic contact lens may become dry and brittle. If this
happens, dispose of the lens and use a fresh new one.
