Vision is a complicated thing that most people do not truly understand. We have all heard about 20/20 vision, but how many people truly know what it means and how optometrists achieve this in their patients? Keep reading to find out more.
What is 20/20 Vision?
20/20 vision is a term that is often used to express what the normal range of vision is. This refers to the sharpness or the clarity of an item or a specific thing that someone can see at twenty feet distance.
Someone with perfect 20/20 vision can see an object clearly at 20 feet distance without having to strain their eyes and without the help of contacts or other corrective lenses. Twenty feet is the average distance that a person can see before the image or the object starts to become blurry or hard to see.
In contrast, someone with vision that is 20/175 can see at a distance of twenty feet what another person would be able to see at 175 feet. In order for them to see something clearly, it must be much closer than it would be for someone with perfect vision.
Visual acuity is an important concept to grasp, especially if you are in need of corrective lenses or contacts, or you have vision that might not be perfect or what might not be considered normal. It is important to visit your eye doctor at least once a year to make sure that if you are having trouble seeing, you get the corrective lenses that you need or you get the care that you need to correct your vision.
How Do Eye Doctors Correct Vision and Check Eye Health?
Eye doctors, or optometrists, work to determine if you have perfect vision or not, what your corrective prescription will be, and what type of lenses you need. There are two major types of vision, nearsightedness, which means you see better close up, or farsightedness, which means you see better further away.
Within the scope of corrective eye services, there are so many different things that can be done to correct your eyes and a huge range of conditions to correct. You may also have what is referred to as astigmatism, this means your eye is oval or football-shaped rather than round.
Visiting an eye doctor every year is a crucial part of making sure your eyes are healthy, adjusting and changing your prescription if need be, and making sure that your eyes are as healthy as possible. Your eyes can change each year and getting a new prescription will help make sure that you are seeing as clearly as possible and that you are not missing some other eye condition that might need to be treated.
