During the Benghazi hearings in 2013, Clinton appeared in public wearing glasses fitted with a Fresnel prism on one lens—something she'd never done before. I've pointed this out for years as a clear indicator of a significant medical issue, likely more than just the "concussion from a fall" that was publicly acknowledged. Understanding this can help people recognize when something's off with their own vision or a loved one's. First, what are Fresnel prisms? They're not your standard eyeglass lenses. These are thin, flexible plastic sheets with a series of tiny ridges (like a flattened lighthouse lens) that stick right onto one side of a regular glasses lens. They work by bending light to shift the image seen by one eye, aligning it with the other to eliminate double vision (diplopia). Double vision happens when the eyes aren't working together properly—often because the muscles controlling eye movement are out of sync or weakened. It's a quick, non-invasive way to patch the problem temporarily, but it's not a cure. Patients use them while waiting for a permanent solution, like ground-in prism lenses, eye muscle surgery, or natural recovery if the underlying issue improves over time. In Clinton's case, that Fresnel prism on her left lens screamed trouble. She started wearing glasses publicly only after her reported fall and concussion in late 2012, which led to a blood clot in her brain. But as a specialist, I can tell you this setup is typically prescribed for persistent diplopia stemming from neurological damage—not just a simple bump on the head. Possible causes? It could be from major trauma disrupting the cranial nerves that control eye muscles, a stroke affecting brain areas responsible for coordination, multiple sclerosis (MS) damaging nerve signals, or even other conditions like thyroid eye disease (less likely for @HillaryClinton) or myasthenia gravis. These aren't minor; they often signal broader health concerns that need ongoing monitoring and treatment. The fact that she wore them during such a high-stakes event suggests the double vision was bad enough to interfere with daily function, and it raises questions about what else might have been going on neurologically that wasn't shared publicly. I've treated patients with similar symptoms, and Fresnel prisms buy time—maybe weeks or months—until we can address the root cause. If it's resolving on its own (like after some concussions), great. But if it's chronic, we move to surgery or permanent prisms to avoid long-term strain, headaches, or falls from poor depth perception. Clinton's team downplayed it as post-concussion recovery, but as a physician, I've always suspected it pointed to something more serious, especially given reports of lingering issues. Attached is a photo from the hearings showing the prism clearly—those vertical lines on the lens aren't a fashion choice; they're medical. If you're experiencing double vision, don't ignore it—see an ophthalmologist ASAP. It could save you from bigger problems down the line.
