Dry eye can result from a number of causes, including both physical and environmental conditions. No matter the cause, the result is a reduction or alteration in any of the three components or layers of a tear – water, mucous and oil – secreted by glands in and around the eye. When this happens, the tear film may not properly coat the eye, leading to loss of moisture, increased dryness and discomfort.
Did you know that nutrition can contribute to your eye health? Many foods – especially fish – contain essential omega-3 fatty acids that help to support eye health.
