20/20 vision explained
The 20/20 scale measures the sharpness of a person’s vision. To test your vision, an eye doctor will place a chart 20 feet away and ask you to read the letters starting with the large capital E at the top and continuing down ten rows of letters. If you have normal 20/20 vision, you can read the first 8 rows of letters from 20 feet. If you have 20/50 vision, you can see at 20 feet away what a person with normal vision sees at 50 feet. And so on.
No matter your number, with the proper vision correction, such as prescription eyeglasses or contact lenses, you can improve your vision and see the world in all its beauty.
