What if i wear two different colour opaque contact lenses, will any harm come to my eyes?

Not necessarily: Herpes will not be cured with antibiotic given for uti, gonorrhea may be cured if given Cipro (ciprofloxacin) for example, but certain strain of gonorrhea are becoming resistant to cipro, (ciprofloxacin) it also can help with chancroid.

Should be OK: There is no problem when wearing contact lenses of different colour, BUT, contact lens is a foreign body, various complications can develop like infection, or trauma. Please make sure how to handle the lenses, clean them, store them and dispose them after a period of time. Please refer to safe use of lenses.
