Stye is infection of Moll & zeis gland present in every body eye lids.Stye occurs due to refractive error as book says but practically it doesn't happen & I have seen happening in persons who have no refractive error,there is no cure for recurrent& multiple states,we only prescribe antibiotic orally as well as for local application in form of ointment. Hot fomentation does only help to certain extent. There is good medicine in homoeopath for recurrent & multiple stye as I had read during my post graduation in a book written by renowned professor of ophalmology of Mumbai, who is no more (Dr muskaty) the drugs named were pulstilla & silicea
