We often overlook taking care of our eyes while in the elements. Dust, wind, sun and dehydration all affect them. Many of us are getting the needed anti-oxidants through our WA, MTN Ops, etc...but we need to supplement Omega-3's. When getting laser eye surgery to correct Magoo-like vision, my doctor had me taking Omega-3's as prescribed a month before the procedure to help fight dry eyes. Also, I used eye wipes to clean the lids to help unclog ducts and remove dirt, oil and pollen. Another thing introduced was eye drops. Use the preservative free single use vials. These can easily be packed on a hunt and can provide excellent relief for hours behind the glass or simply lubricate dry eyes after a monster hike. For those with chronic dry eyes, a doctor can quickly implant plugs into the tear ducts. I hope this gets some of you folks thinking.
