Placebo Comparator: Control
30 volunters with no signs of blepharitis and with eyelashes with no demodex .None intervention. Symptoms and signs will be compared with experimental group



Primary Outcome Measures :
  1. Erradication of Demodex mites [ Time Frame: 2 months ]
    Reduction in mites count after treatment compared to baseline data. If mites are not observed in the last visit a complete eradication will be considered. Patients with one or more mites will be considered as a incomplete eradication


Secondary Outcome Measures :
  1. Change in lid margin rednes and bulbar conjunctival hyperemia categorized from 0 (none) to 3 (severe) according to the next score [ Time Frame: 2 months ]
