Many people construe that someone stating they have 20/20 vision means that the person has perfect visions, the eyes of an eagle. But many people are surprised to find out that 20/20 is not perfect vision. Someone with 20/15 vision has extremely sharp vision, and would be able to see a line on the eye chart from 20 feet away, while the average person could probably only see at about 15 feet away.
Typically, eyeglasses and contacts are prescribed in order to let us see with 20/20 vision. So, what exactly does that even mean? 20/20 simply describes normal vision. The reason it is referred to as “20/20,” is because it means that the person is able to see clearly at 20 feet away, as they normally should be able to do. To dissect the numbers a little bit further, we can examine another example. Let’s say you have 20/50 vision, this means that you need to be as close as 20 feet in order to see what a person with “normal vision” could see at 50 feet away. Technically, the higher the latter of the numbers, the worse your vision would be.
An adult with naturally 20/20 vision isn’t common, as only about 35% of all adults have 20/20 eyesight without using eyeglasses, contact, or undergoing corrective surgery. And with corrective measures, only about 75% of adults have 20/20 vision. The fact remaining at hand is that many adults falsely believe their vision to be better than it actually is. Many people don’t realize they aren’t seeing as sharply as they could be until they actually are given the opportunity to see through the lens of corrective glasses, which is why it’s important to regularly visit your optometrist in Arlington.
According to the American Academy of Ophthalmology, it is recommended to have your child’s vision tested as soon as they reach an age that is old enough to cooperate undergoing an eye exam. Surprisingly enough, after the age of about 8 or 9 years old, most people’s vision acuity stays about the same, usually only decreasing around their 60’s or 70s. It is common however, for most middle-aged people to suffer a decrease in the ability to see up close. As we age, our eye’s lenses, like most of the muscles in our body, become less flexible which makes it more difficult for the eye to focus, therefore negatively affecting one’s near vision.
As we mentioned, many people falsely believe that their vision is much better than it actually is, and this is one of the reasons why it is so important to have your eyes checked regularly. Not only does unclear vision often go unnoticed, but there are many other eye problems that can occur with silent symptoms.
