<p>If you are not comfortable wearing contact lenses, it could be due to degradation of the lipid layer in the eyes' natural tear film, says a study.<br /><br /></p>.<p>Patients with discomfort showed degradation of the lipid layer after a few hours of wearing contact lenses, the researchers found.<br /><br />The tear film is a three-layered "sandwich" of fluids that nourishes and protects the eyes.<br /><br />The lipid layer is the tear film's outermost layer, which is composed of fat- and wax-like molecules called lipids.<br /><br />It performs an important barrier function in preventing evaporation of tears and maintaining stability of the tear film.<br /><br />"Discomfort is the primary reason why otherwise successful contact lens users do not wear contact lenses," said Anthony Adams, editor-in-chief of Optometry and Vision Science, the official journal of the American Academy of Optometry.<br /><br />"Our authors identified the changes in the lipid layer of the tear film in people who have discomfort wearing contact lenses," Adams added.<br /><br />The researchers found that applying an eyelid spray appeared to reduce drying of the tear film and help make wearing contact lenses more comfortable.<br /><br />After the spray was used on the eyelids, the stability of the tear film increased significantly.<br /><br />The study appeared in the journal Optometry and Vision Science.</p>
