You have a vitamin A deficiency
Not enough vitamin A can also lead to dry eyes, although this is more common in developing parts of the world.
This is relatively easy to fix as the nutrient is found in many foods—leafy green vegetables like broccoli; orange-colored vegetables like sweet potatoes, carrots and pumpkin; and liver.
Other aspects of a healthy diet can be critical to eye health. Studies suggest that omega-3 fatty acids may reduce symptoms of dry eye.
The compounds are found in fish (especially salmon and sardines), and walnuts.
