Eye doctors have said that US Secretary of State Hillary Clinton is wearing a pair of special eyeglasses that have a lens which is used to treat double vision.
Clinton, recently treated for a blood clot near her brain after a fall, wore the Fresnel lens to aid her left eye during the Benghazi hearing.
Dr. Vike Vicente, a pediatric ophthalmologist in Bethesda, Md. Described it as a kind of prism that helps people who are experiencing double vision, Fox news reports.
According to the report, State Department spokesman Philippe Reines said that Clinton 'would be wearing these glasses instead of her contacts for a period of time because of lingering issues stemming from her concussion.'
He added that Clinton "got a kick" out of seeing a light-hearted NY Magazine photo-essay of her various glasses-wearing poses during recent Senate testimony, which he said she saw "crystal clear."
