I'm not a heavy tv watcher, but was at a relative's house late last month. A tv was on in the background and after a while I noticed that Restasis was advertising very heavily. The ads were attempting to educate consumers on DED. The ultimate message was "see your eyecare professional and get tested". IMO this campaign by Allergan equates to huge free advertising for Tearlab.
I also note that for the past couple of quarters, management has hinted at osmolarity testing getting expressly incorporated into eyecare best practices - the current investor deck on the website expressly states this will happen mid-2016.
Given that we are currently at 52 week lows, we could see a significant bump from these levels due to any positive news.
