What does eye flash mean?

Some people feel a bright spot in front of their eyes when they overuse their eyes, as if there is a white light, which is particularly dazzling. If this phenomenon is transient, it means that it is just caused by eye fatigue. There is no need to worry too much. As long as the eye fatigue is relieved, the symptoms of eye flashes will naturally disappear. However, some people experience flashes in their eyes due to posterior vitreous detachment or intracranial lesions. In this case, they should go to the hospital for treatment in time.

1. Causes of eye flashes

1. The most common cause of flashes in ophthalmology is vitreous pulling on the retina, which is one of the symptoms of posterior vitreous detachment. Posterior vitreous detachment occurs suddenly, and the main symptoms of patients include floaters and flashes, and sometimes black circles can be seen in front of the eyes. Especially people with high myopia often have floaters. The patient feels that there are floating dots or hair-like turbidities in front of his eyes, which last for a while and then disappear, but may reappear or persist later, and their number and shape rarely change. Usually no treatment is required. But be sure to rest your eyes! If similar symptoms occur frequently, or if local visual field loss occurs suddenly, you should go to the hospital to check the fundus in time to prevent retinal detachment. Pay attention to changes in symptoms and seek medical attention if they worsen.

2. The following are other reasons for eye flashes: intracranial lesions, migraine, orthostatic collapse, hypoglycemia, hypotension, temporary cerebral anemia, retinal detachment, posterior vitreous detachment, visual impairment, multiple transient white dot syndrome, uveitis, retinal tear, multiple easily dissipated white dot syndrome, sphenoid sinusitis, pathological myopia, extensive fibrosis of the extraocular muscles syndrome, birdshot retinal choroidopathy, acquired retinoschisis, choroidal metastatic carcinoma, vascular retinopathy, and uveitis.

2. What can you eat to protect your eyes?

1. For staple foods, focus on yellow grains such as yellow corn, millet, and rhubarb rice, which contain lutein, zeaxanthin, and carotene; purple rice, black rice, etc., which contain anthocyanins. The staple food arrangement every day, apart from white rice, is white flour, which is very detrimental to the anti-aging of the eyes. All of these whole grains and beans also contain vitamin E and B vitamins needed to fight eye fatigue. 2. Vegetables: Pay attention to various dark green leafy vegetables such as spinach, rapeseed, and Chinese cabbage, which contain a lot of lutein, carotene and vitamin C; there are also purple-red vegetables such as purple cabbage, red amaranth, and purple cabbage, which contain anthocyanins and vitamin C.

3. For fruits, pay attention to red, purple and blue fruits such as blueberries and strawberries, which are rich in anthocyanins and vitamin C; mangoes, papayas, citrus fruits, etc., which contain carotene and vitamin C. Everyday fruits such as apples, pears and peaches have very limited effects. 4. The last eye-protecting food to be introduced is wolfberry, which is the richest natural food in lutein and is also particularly rich in carotene.
