Dry eye can result from a number of causes, including both physical and environmental conditions. No matter the cause, the result is a reduction in any of the components of a tear that are secreted by glands in and around the eye or an alteration of any of the layers of the tear film - lipid, aqueous or mucous layers. 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. Talk to your doctor before making changes to your diet.
