just eh [SEP] i was diagnosed with bells palsy and this was recommended to me as i have been taping my eye shut for the past two months there are definitely positives and negatives to it overall i wish the string was more comfortable and that the foam was slightly sticky so that it would adhere to my face so it would not move around as muchpositives overall it does work i am able to function for a lot longer than i could with the drops alone i had to add a drop of liquid in order to really get the humidity in the patch to start to build up honestly i am going through a lot so crying is not abnormal right now so that happened on its ownnegatives the string is very uncomfortable it really needs to be much thicker so that it does not cut into the skin i was not able to sleep with this as the only protection for my eye as i move around a lot and because it does not stick at all i would have knocked it off easily
