Your eye health matters


Our eye health and vision can be compromised by many different factors, from our diet and environment to age and lifestyle. Here are a few of the most common conditions that affect people every day.


Dry Eye is a condition where the surface of the eye becomes inflamed and sore due to an imbalance between the tear film and the eyelids. This might be because you have a deficiency in the quality or quantity of your tears.


Blepharitis literally means ‘inflamed eyelids’. It can be the skin area around the eyelashes that is inflamed, or the area around the oil-producing (Meibomian) glands, or both. It is a chronic condition that can be controlled, but not often cured.


As we get older, particularly over the age of 60, we are more prone to developing eye problems. Age-related Macular Degeneration (AMD) Is a common cause for poor vision in older people.


Ocular Allergies also known as allergic conjunctivitis are very common, the same allergens that cause sneezing and runny noses can also irritate your eyes leading to symptoms including itchy, watery and red eyes. The most common cause of allergic conjunctivitis are seasonal triggers such as pollen.


A chalazion is a hot, red, painful lump under or on the eyelid, which appears within a day or two. Its size may be that of a lentil or a pea, or sometimes even an olive. The chalazion may be on the outside of the eyelid and may be seen easily, but it can also be on the inner side: from the outside, the eyelid is simply red and swollen, and the eyelid must be everted to see the chalazion.


The stye is an infection of the implantation area of an eyelash called the “pilosebaceous follicle. It presents itself as a small, red, hot and painful bulge the size of a grain of barley located on the edge of the eyelid and centred on one eyelash. It appears within a day or two then when it ripens, it forms a pocket of visible white-yellowish pus on the surface of the stye.


Demodex is an eight-legged mite from the Demodicidae family. There are many species of Demodex but only two of them are found present in humans, demodex folliculorum and demodex brevis. Demodex mites are found naturally on the faces of human beings from childhood, but especially after the age of 18.


Antioxidants, such as Vitamin A and Vitamin C, and other important nutrients have been shown to have a positive effect on eye health and reducing certain conditions. Vitamins and minerals have also been shown to be essential for good vision.
