Abstract: Provided are processes for increasing secretion of meibum in a subject in need thereof, where the processes may include or be exclusively: applying light emitted from a treatment apparatus to an outer surface of one or more eyelids of the subject, the light emitted from the treatment apparatus having a predetermined set of photomodulating parameters, the light emitted from the treatment apparatus comprising or consisting of one or more wavelengths from 380 nm to 500 nm, and increasing secretion of meibum in the subject thereby. It was found that particular short wavelengths of light promote movement of meibum thereby treating or preventing one or more conditions of the eye related to suboptimal meibum secretion.

Abstract: Provided are methods and systems for treating or preventing dry eye syndrome in a subject. The methods involve applying light of a set of photomodulating parameters to the region of the eyelid. The light of these particular photomodulating parameters will increase the production of collagen, elastin or both thereby improving the tone of the eyelid. Improved eyelid tone will increase the level of meibum secreted through the meibomian duct thereby treating or preventing dry eye syndrome. Particular apparatuses are provided that emit and locate light of the necessary photomodulating parameters tailored for delivery to the eyelid areas activating fibroblasts specifically in this area and thereby improving eyelid tone and meibomian gland function.
