Hillary Clinton is becoming a poster child for how difficult recovering from a concussion can be.
Last Wednesday when Clinton testified about the attack on the U.S. Consulate in Libya, the New York Daily News noticed that one of her eyeglass lenses had a Fresnel prism. That device helps people with double vision or muscle weakness focus their sight.
And in fact, a Clinton spokesperson told the News that the eyeglasses were necessary as the result of the concussion she suffered when she fell and hit her head a month ago.
New York Magazine followed up on the story, and Clinton’s spokesman said that the former First Lady will “be wearing these glasses instead of her contacts for a period of time because of lingering issues stemming from her concussion.”
The Daily News then interviewed several doctors, who theorized that Clinton is suffering from double vision because she damaged her 6th cranial nerve – either when she struck her head or due to a blood clot she had behind her ear shortly after her concussion.
The experts noted that double vision and blurred vision are common after someone suffers a concussion. And one told the Daily News that if Clinton’s injury causing the double vision was in the brain, rather than the nerve, it could be permanent.
