Review (3/5): Works well for mild to moderate cases of Bells Palsy in my opinion.
I used this when I was suffering from a mild case of Bell's palsy. I was still able to blink somewhat unlike moderate/severe cases of Bell's where you can't blink to close the eye, period. Worked wonderfully when I needed it the most. I got Bell's prior to taking my medical board exams. This helped me during that marathon of an exam so I didn't keep tearing up. It was a pain to manually keep using my fingers to blink every few seconds to keep my eye lubricated.
Overall, I recommend this patch. Only drawback I had was that it would constantly fog up which is a good thing, but when taking a 9 hour exam on the computer ... not so much. Also, make sure to get some liquid gel eye drops. Regular Visine won't cut it, so get something like GenTeal which can be found OTC and most pharmacies.
Also make sure to see your Physician/Neurologist and/or Optometrist and follow up with them as needed. Bell's palsy can make your eyes especially vulnerable to drying out and ulcerations.
