Thank you for the suggestion. I tried to drink two bottles of water during golf today instead of one. It's certainly possible that we don't drink enough water, but it's also possible that aging plays a part in dry eye syndrome.
I have dry eye syndrome. Take the Omega oils, and drink tons of water. It just might start helping. Include good oils in your diet, olive oil, and coconut oils too. Cold pressed are best.
I also take nutrient vitamins for the eye. Many brands out there. There are goggles to help retain moisture in the eye while you sleep as well.
