I wear a scleral lens during the day, because of the lens I don't use lubricant every 1-2 hours anymore. Dr. Ken Maller, Ft. Lauderdale, FL is THE BEST for scleral lens, if you're not in the area & can't travel, find someone near you who is proficient in scleral lenses. It was a life saver for me, now I love the wind in my face! I also put lubricant in at night when I take the lens out, then use the NITEYE bubble bandage, it makes a 'moisture chamber' for the eye & protects the cornea at night (so my open eye doesn't get scratched on the pillow). The NITEYE bubble bandage is kind of pricey, I buy them by the case. You can also cut a piece of saran wrap & tape it around your eye - I did that before I found the bubble bandage, but it was a pain in the neck & because I have long eyelashes they would bother my eye, so the bubble is best for me. So that's my protocal.
Definitely get the weight for your upper eyelid - I have a platinum weight. Also, if you can find someone to do a canthal lateral sling on your lower lid it's best, it'll last longer. & yes, the older we get, our eyes get dry, so I understand the dryness you're experiencing in your non AN eye.
