  • Gender: Male or Female

Inclusion Criteria:

  • Subject is able to read, understand and sign an Informed Consent (IC) form
  • 22-85 years of age
  • Subject is able and willing to comply with the treatment/follow-up (FU) schedule and requirements
  • In the study eye, TBUT 7 seconds
  • In the study eye, Meibomian Gland Score (MGS) 12
  • In the study eye, at least 5 non-atrophied meibomian glands in the lower eyelid
  • Symptoms self-assessed using the Ocular Surface Disease Index (OSDI) questionnaire 23

Exclusion Criteria:

  • Fitzpatrick skin type V or VI
  • Contact lens wear within the month prior to screening
  • Unwilling to discontinue use of contact lenses for the duration of the study
  • Ocular surgery or eyelid surgery, within 6 months prior to screening
  • Neuro-paralysis in the planned treatment area, within 6 months prior to screening
  • Other uncontrolled eye disorders affecting the ocular surface, for example active allergies
  • Current use of punctal plugs
  • Pre-cancerous lesions, skin cancer or pigmented lesions in the planned treatment area
  • Uncontrolled infections or uncontrolled immunosuppressive diseases
  • Subjects with ocular infections, within 6 months prior to screening
  • Prior history of cold sores or rashes in the perioral area or in the planned treatment area that could be stimulated by light at a wavelength of 560 nm to 1200 nm, including: Herpes simplex 1 & 2, Systemic Lupus erythematosus, and porphyria
  • Within 3 months prior to screening, use of photosensitive medication and/or herbs that may cause sensitivity to 560-1200 nm light exposure, including: Isotretinoin, Tetracycline, Doxycycline, and St. John's Wort
  • Over exposure to sun, within 4 weeks prior to screening
  • Use of prescription eye drops for dry eye, within 7 days prior to screening, excluding artificial tears and glaucoma drops
  • Radiation therapy to the head or neck, within 12 months prior to screening
  • Planned radiation therapy, within 8 weeks after the last treatment session
  • Treatment with chemotherapeutic agent, within 8 weeks prior to screening
  • Planned chemotherapy, within 8 weeks after the last treatment session
  • New topical treatments within the area to be treated, or oral therapies, within 3 months prior to screening- except over-the-counter acetaminophen-based analgesics for pain management, new oral omega 3 fatty acid supplements and topical artificial tears
  • Change in dosage of any systemic medication, within 3 months prior to screening
  • Anticipated relocation or extensive travel outside of the local study area preventing compliance with follow-up over the study period
  • Legally blind in either eye
  • History of migraines, seizures or epilepsy
  • Facial IPL treatment, within 12 months prior to screening
  • Any thermal treatment of the eyelids, including Lipiflow, within 6 months prior to screening
  • Expression of the meibomian glands, within 6 months prior to screening
  • In either eye, moderate to severe (Grade 3-4) inflammation of the conjunctiva, including: allergic, vernal or giant papillary conjunctivitis
  • In either eye, severe (Grade 4) inflammation of the eyelid, including: blepharochalasis, staphylococcal blepharitis or seborrheic blepharitis
  • Ocular surface abnormality that may compromise corneal integrity in either eye (e.g., prior chemical burn, recurrent corneal erosion, corneal epithelial defect, Grade 3 corneal fluorescein staining, or map dot fingerprint dystrophy)
  • Eyelid abnormalities that affect lid function in either eye, including: entropion, ectropion, tumor, edema, blepharospasm, lagophthalmos, severe trichiasis, and severe ptosis
  • Any systemic condition that may cause dry eye disease, including: Stevens-Johnson syndrome, vitamin A deficiency, rheumatoid arthritis, Wegener's granulomatosis, sarcoidosis, leukemia, Riley-Day syndrome, systemic lupus erythematosus, and Sjgren's syndrome
  • Unwilling or unable to abstain from the use of medications known to cause dryness (e.g., isotretinoin, antihistamines) throughout the study duration. Subjects must discontinue these medications for at least 1 month prior to the baseline visit.
  • Any condition revealed whereby the investigator deems the subject inappropriate for this study
