need to know some help please…! Answer 1No. But I highly doubt his vision was measured as 50/50. That’s like saying I’m 3ft 36in. Technically, it’s the same as 6 feet, but that’s not how we measure height.
The first number is the eye chart distance. The second number is the size of the smallest letters you can read at that distance. So 20/50 means you can read a 50-size letter at 20 feet. 20/30 means you can read a letter from 30 to 20 feet away (which is better). 50/50 means you can read a letter size of 50 to 50 feet. Since the eye cards are always 20 feet away, no one is going to test you and find out you’re 50/50. Please ask your provider again about your visual acuity as I’m sure you weren’t measured at 50/50 Answer 2 Some airlines require their pilots to have 50/50 vision. And 50/50 is not exactly the same as 20/20. It is true that the numerator represents the distance between you and the graph. 20 feet is considered a sufficient distance for your lens to attempt to focus at approximately infinity. But 50 feet is more accurate. If you have 50/50 vision without glasses, your eyes are considered healthy and you don’t need glasses in a normal situation Answer 350 50 Vision is meaningless. vision is measured by the top number being the number of feet on an eye chart (always 20) and the bottom number being the line on the eye chart that you can read without error. for example, 20 30 is below average and 20 10 is above average
