In daily life, people often use some electronic products, the most common ones include mobile phones, tablets, televisions, etc. Children nowadays especially like to use electronic products to play games or watch cartoons, etc. If parents do not stop them, these practices will hurt children’s eyesight. Some children’s vision is 46 when they go for testing. How many degrees is this? What is the visual acuity of 46? A vision of 4.6 indicates mild myopia, which can be corrected by wearing glasses with a degree of 50 to 75. If it is false myopia, you do not need to wear glasses, as it will get better after a period of adjustment. Do not wear glasses often if it is required for work. If you are a student, you must keep your vision from getting worse. If your vision deteriorates, you must wear glasses. Based on the medical history and age provided, it is recommended that the patient go to the hospital for further optometry examination and consider laser myopia surgery if necessary. Pay more attention to the correct eye posture and eye habits in daily life. There is not much relationship between naked eye visual acuity of 4.6 and myopia degree, but it can be clearly told that if the visual acuity remains at 4.6 and there is no improvement after a good rest, in most cases you are already myopic. The degree is generally around -1.00DS~-1.50DS, usually not exceeding -2.00. After all, if a myopic patient squints to see things, his vision can be temporarily improved in a short period of time. Therefore, 4.6 does not have much meaning. : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : |
