Myopia of 50 degrees is in the range of low myopia, usually around 0.7-0.8 vision when looking at the visual acuity chart. In the case of small children, 50 degrees of myopia also requires attention, because once myopia occurs in children, it will certainly gradually deepen. If you have 50 degrees of myopia after the optometry, you need to fully increase outdoor activities, to ensure two hours of outdoor activities every day, every six months to review the results of the optometry, if the degree of growth is faster, you need to wear glasses to correct and improve vision can be. If the prescription still grows more than 75 degrees per year, we should consider wearing OK lenses or low concentration of atropine drops to control the development of myopia. If it is 50 degrees of myopia in adults, it tends to have a relatively small impact on vision and both eyes can see between 0.8-1.0, which is basically enough vision in daily life. However, if you are driving or watching a movie, which has a greater impact on your vision, you can wear a pair of glasses as a backup, and wear them while driving or watching a movie to ensure clear vision.
