Whats the vision level corresponding to the third line on the eye chart?
Checking one's vision is a straightforward process that can be done using a vision chart. The different characters on the chart allow for a basic assessment of visual acuity. If one can only read the third line of the vision chart, their visual acuity is approximately 0.2. However, this does not represent the degree of myopia, and a professional eye examination and refraction test are required for accurate determination. If a conversion is necessary, this visual acuity typically corresponds to a myopia range of approximately 200 to 250 degrees. It is important to note that wearing glasses does not simply add to this measurement, and a new refraction test may be required.
1. Vitamin A: Known as a "necessary nutrient for eye health," vitamin A is essential for preventing dry eyes, vision decline, and night blindness. It is found abundantly in carrots, green and yellow vegetables, and red dates.
2. Vitamin B: Vitamin B is one of the nutritional sources for the visual nervous system. A deficiency in vitamin B1 can lead to eye fatigue, while a deficiency in vitamin B2 can cause keratitis. Foods rich in vitamin B include sesame, soybeans, fresh milk, and wheat germs.
3. Goji Berries: The benefits of goji berries for clearing the liver and improving vision are widely known. They are rich in carotenoids, vitamins A, B1, B2, C, calcium, iron, and other nutrients essential for healthy eyes.
