          4. Has a history of any of the following ocular (eye or eyelid) conditions or procedures
             in either eye within the past 90 days prior to the screening visit:

               1. Ocular trauma

               2. Chemical burns

               3. Ocular Herpes simplex or Herpes zoster infection

                  keratitis)

          5. Has undergone ocular surgery (e.g. intraocular, oculoplastic, corneal or refractive
             surgery procedure) within the past 12 months prior to the screening visit;

             (grade 2-4) allergic, vernal or giant papillary conjunctivitis; a hordeolum or stye;
             ocular surface abnormality that may compromise corneal integrity (e.g. Grade 3 corneal
             fluorescein staining, recurrent corneal erosion, corneal epithelial defect, map dot
             fingerprint dystrophy, previously treated chemical burn);

          8. Has an eyelid abnormality that affects normal lid function (e.g. entropion, ectropion,
             oedema, blepharospasm, lagophthalmos, severe trichiasis, severe ptosis);

          9. Has a systemic condition that in the opinion of the investigator may affect a study
             outcome variable;

         13. Has a history of sensitivity to rapidly blinking lights or photosensitive epilepsy;

         16. Is a member of CORE directly involved in the study;

         17. Has taken part in a clinical research study within the last 30 days. * For the
             purposes of this study, active ocular disease is defined as infection or inflammation
             which requires therapeutic treatment. Mild (i.e. not considered clinically relevant)
             lid abnormalities (blepharitis, meibomian gland dysfunction, papillae), corneal and
             conjunctival staining and dry eye are not considered active ocular disease.
             Neovascularization and corneal scars are the result of previous hypoxia, infection or
             inflammation and are therefore not active.
