As computers and cell phones are used more and more frequently, we can often hear our friends around us say that they feel dry eyes and the number of people suffering from dry eyes is rising. Some people may think it’s not just about the eyes, it’s not a big deal, but it’s not. Dry eye is a common eye surface disease with potential harm, and further development can affect other eye tissues such as the cornea, and even lead to serious harm such as vision loss. So don’t ignore this common condition. There are many symptoms of dry eye, including: dryness, foreign body sensation, redness, burning sensation, fluctuating vision, etc. However, these symptoms alone cannot fully confirm the diagnosis of dry eye. In addition to treatment with artificial tears and other medications, what should we pay attention to in our diet to improve dry eye? First of all, the occurrence of dry eye is often related to the lack of vitamin A in the diet, so patients with dry eye can supplement their daily diet with fresh vegetables and protein-rich foods, as well as carotene, which can be converted into vitamin A to make the conjunctival epithelial cells of the eye secrete mucus, thus reducing the symptoms of dry eye. Spicy and stimulating foods are not suitable for dry eye patients, and alcohol should be consumed sparingly. Secondly, we can also supplement essential fatty acids, which are essential for human life metabolism, but cannot be synthesized by human body, and can only come from food, the two main essential fatty acids are Omega-3 and Omega-6, of which Omega-3 is very important (short chain ALA and long chain EPA, DHA). A study in the United States in 2005 found that women who loved deep-sea fish had a lower rate of dry eyes than women who loved meat (pork, cattle). Omega-3 is a natural anti-inflammatory substance that keeps the lipids of the lid glands fluid and assists in the regeneration of damaged corneal nerves, among other functions. 32,000 studies of women with low intake of Omega-3 in relation to dry eye found that increasing oral intake of one gram of Omega-3 per day reduced the incidence of dry eye by 30%. Therefore, dry eye and patients with dry eye symptoms can pay attention to Omega-3 supplementation in their regular diet, while reducing the use of visual screen terminals such as computers and cell phones, and supplementing with medications such as artificial tears, which will greatly help the improvement of symptoms.
