I had to check it out a week or so ago. A fresnel lens compensates for visual distortions due to stroke.

I’ve suspected a small stroke for a while. The sudden need for thick glasses...and the puffiness and weight gain could be from strong medication.

The MSM likes to call what she had "a blood clot". But search "transverse sinus thrombosis"; that's a little more serious.

Beyond observation, the only way to know if she has sustained permanent brain damage is if she releases her medical records (As was the case with Bill Clinton's and Obama's full medical records -- the chances of that happening are absolute zero.)

(The MSM seems to have little interest in brain pathology when it comes to Democrat candidates. Joe Biden had two brain surgeries, often exhibits quite bizarre behavior and there's been no interest as to why that might be the case.)
