My doctor is big on Tears Natural II – 2 drops, 4x daily - so that is what I use. Remember that whatever you try must be a eye "lubricant" and NOT contain any of the red eye or other stuff.
I also found this some time ago -- didn't actually do a trial test to prove/disprove any of this worked, but it might be worth checking your diet for these vitamins.
VITAMINS AND MINERALS
The following are some of the essential nutrients for treating dry eyes:
• Vitamin A: In parts of the world where vitamin A deficiency is widespread, severe dry eye syndrome is a leading cause of blindness. Vitamin A is needed for the health of all epithelial (surface) tissues; it is actually found in the tear film of healthy eyes, and is fundamental to the production of the mucous layer of the tears.
We recommend eye drops containing vitamin A because they protect the eyes from free radicals, such as toxins, irritants, allergens and inflammation. In addition, take a daily dose of 10,000 I.U. of vitamin A and 25,000 I.U. of beta-carotene (also called pro-vitamin A because it converts to vitamin a in the body).
Note: before beginning a regimen of vitamin A or beta-carotene, have your thyroid activity checked by your doctor. Hypothyroid patients - people with underactive thyroids - are always vitamin A deficient. They cannot convert beta-carotene to vitamin A, nor can they convert vitamin A to the form usable by the eyes. One way to check this yourself is to take your temperature under your arm when you wake up in the morning, but before you get out of bed. If it is regularly below 97.8 F degrees , you might have any underactive thyroid.
• Vitamin B6: All of the B vitamins are important in treating dry eyes, but vitamin B6 aids in the proper absorption of magnesium. Magnesium helps the body produce a hormone called prostaglandin E-7, which is necessary for tear production.
• Vitamin C: Vitamin C is concentrated in the tear film to a higher level than that found in the blood.
• Potassium: Probably the most important mineral for dry eye symptoms, potassium is usually very low in dry eye patients. This is usually linked to low intakes of folic acid, vitamin C and vitamin B6 along with high sugar consumption. You can take in at least 500 mg per day by increasing your consumption of fruits and vegetables (one banana contains 400 mg).
• Essential Fatty Acids: These are important for the production of both the oily, lipid and the watery aqueous layers of the tear film. After only ten days of taking essential fatty acids plus vitamins B6 and vitamin C, dry eye sufferers have seen an increase in tear production.
