The term 20|20 vision does not come strange to a lot of people. You may have even used it yourself without knowing its actual definition. It represents a clear vision to most people, and quite frankly, they are not very far from the truth. So now, what is the actual meaning of a 20|20 vision?
In this article, we will be describing the term 20|20 vision, what it actually means and how you can achieve it.
How common is 20|20 vision?
Most people do not have complete vision without wearing contact lenses or eye glasses. According to studies, only 35% of the adults have full vision without the need to wear their glasses or lenses. You may contact your eye surgeon who will suggest about the right option to improve your vision.
Does 20|20 vision mean perfect eyesight?
In a way, 20|20 vision refers to the sharpness of one’s vision or visual acuity. The term consists of two numbers, one on the numerator and the other on the denominator.
The numerator refers to the distance from the patient’s eyes to the eye chart. This is usually 20 feet. If an individual can read all the letters on the eye chart from this distance, then the individual is said to have a 20|20 vision. However, suppose an individual can only read the larger lines of letters on the chart. In that case, you may have a 20|40 vision or a 20|60 vision.
On the other hand, the denominator refers to what a person can see compared to what a person who has a 20|20 vision see. For example, having 20|20 vision means the individual sees what a normal person sees at 20 feet. On the other hand, having a 20|40 vision means the individual can see at 20 feet what a normal person sees at 40 feet.
However, 20|20 is not the penultimate in terms of vision, as 20|10 and 20|15 visions are better than 20|20 vision. A person with a 20|10 vision can see at 20 feet what a normal person can see at 10 feet. The same principle is applied to a 20|15 vision. Basically, a 20|20 vision is seen as the average vision. There has been evidence of people having 20|10 or 20|15 visions, which is very impressive in its own right.
How can one achieve a 20|20 vision?
20|20 vision seems like a great idea for people who have problems with their eyesight or people who have refractive errors. For some other groups of people, achieving a 20|20 vision.
For instance, people with myopia or short-sightedness and hypermetropia or long-sightedness can achieve a 20|20 vision by going for laser eye surgery. Laser eye surgery for people with myopia or hypermetropia works by surgically altering the shape of the cornea with bladeless technology. This action corrects the focus on the retina, ultimately correcting the vision. Laser eye surgery can also treat other refractive errors like astigmatism.
People with other eye problems like cataracts will not correct their eyesight problems through laser eye surgery. Instead, they can have their vision corrected through cataract surgery. The surgery involves the removal of the cloudy lens that is responsible for blurred vision. Besides cataract surgery, the vision can be corrected, and 20|20 vision is achieved through Refractive Lens Exchange (RLE) or Implantable Collamer Lenses (ICL).
If you do not have any problems with your eyesight, you are more likely to achieve 20|20 vision with common prescriptions.
Achieving a 20|20 vision after years of wearing contact lenses or glasses sounds like the best news yet. Previous patients have confirmed the success of eye surgeries to correct eyesight and how 20|20 vision has made their lives easier.
