A dry gritty eye is often a sign of a dry eye and much less common in men than in women. Often the eyes become infected and a good remedy to prevent infection is the use of a quality artificial eye drop used as often during the day as is needed. Good nutrition, which means a diet full of the correct amount of protein fat and carbohydrates is required but also especially over the age of 55 years of vitamin supplement is a really good idea. Consider asking a nutritionist about healthy meal ideas. Often this saves taking out the cookbook and keeps the required list of ingredients to the minimum necessary, thus avoiding waste or worse still, overeating.
