Did you know there are two main types of dry eye conditions?
ADDE: Aqueous Deficient Dry Eyes – which is simply defined as a reduction in the production of tears from the lacrimal gland.
EDE: Evaporative Dry Eyes – which is the loss of the lipid layer from the surface of the tear film where there is a normal production of tears. This type of dry eye can be confusing as the eyes are still watering but due to the loss of the protective lipid layer, it is unable to retain moisture on the surface and still feels irritated.
Meibomian Gland Dysfunction MGD is the result when the Meibomian glands cease to function optimally. MGD is associated with EDE. These blocked glands can no longer secrete the oils necessary to maintaining a healthy tear film.
MGD is often thought to be the leading cause of dry eye disease. If MGD is left untreated for an extended period of time, permanent damage to the eyes may occur.
Although, dry eyes are broadly classified into these two categories, they are not mutually exclusive and you can have a combination of the two.
Eating certain foods can help with dry eyes. These include:
1. Foods rich in potassium such as bananas, sweet potatoes, potatoes, white beans, yogurt and soybeans.
2. Foods rich in antioxidants such spinach, kale, Goji berries and blueberries to protect the eyes from free radicals damage.
3. Omega 3 for anti-inflammatory effects in foods such as cold-water fish, walnuts, pumpkin seeds, flaxseeds, chia seeds, palm oil and soybean oil.
4. Zinc helps Vitamin A create a pigment melanin which protects our eyes. Fish,legumes, liver, mushrooms, sunflower seeds and whole grains are rich in zinc. As our body doesn’t store zinc, it is important to get enough from daily dietary intake.
5. Water is essential for keeping our body function properly and eyes are no exception to this. To keep our eyes hydrated an intake of 8 to 10 glasses of water is recommended.
