Here's something I didn't know--people with MSA blink less. Plus people that stare at computer screens all day (like me) do too. A normal rate is 10-15 times per minute. The eye doctor suggested over-the-counter artificial tears, 3 times per day. Easy solution, but costly. I thought "if you don't blink enough, just blink MORE". I find adding those drops at night when I'm lying in bed is easier.

Here are other low or no cost ideas:
1. Warm washcloth compress. 
2. Salmon--in this case, the omega 3 can improve the eye’s oil film, also is an anti-inflammatory.
3. Computer breaks. 20-20-20 rule: Every 20 minutes, spend at least 20 seconds looking at something 20 feet away.
4. Blink more. I have post-its stuck on fridge, computer screen, tv etc
