I take fish oil, sea buckthorn oil. Do Systane PF eye drops and ointment, and warm compresses. I’m female so I take bio identical hormones. To low estrogen can dry you up everywhere. I have tried the expensive eye drops and the tubes but it didn’t help. I had multi focal lens replacement 6 years ago and my kind of dry eyes went from a 3 to a 9. I just should have opted for new glasses. I did t have cataracts, I just wanted to se close near and far. Now I can’t see in bright sunlight, or at night. I have had sclera abrasions from this. It’s a pitiful thing.
