Usually, 20/20 vision is regarded as normal eyesight. However, it is stated to define the lucidity through which a person views something from a 20 feet distance. Whereas, 20/15 eyesight means that you may view something from a 20 feet distance, which an individual with normal eyesight might see clearly from 15 feet.
If you have 20/30 vision, this means, that you can see at 20 feet what the âaverageâ person can see at 30 feet, and it goes on from there. So, your optometrist will determine your visual acuity, based on the 20/20 model, and design a prescription to help you come as close to 20/20 vision as possible.
