What is 20/20 Vision And How To Achieve It?
What is 20/20 vision? The most common practiced way to measure vision in a clinical setting is using standard letter charts, called a Snellen chart, with a single large letter at the top and rows of progressively smaller letters continuing down the chart.
In the United Kingdom, the standard placement of the eye chart is on a wall that’s 20 feet away from your eyes. Since many eye doctors’ rooms aren’t 20 feet long, in a smaller room the eye chart may hang behind the patient chair, using mirrors to make it appear in front of you at a simulated distance of 20 feet.
So What Is 20/20 Vision Exactly?
So if you can read the letters on the ’20’ line (which is the green shaded line at the lower end of the chart) from 20 feet away – then you have 20/20 eyesight.
However, most people are able to see better than 20/20 after laser vision correction. See our laser eye surgery results for more information.
According to the American Optometric Association, “20/20 vision is a term used to express normal visual acuity (the clarity or sharpness of vision) measured at a distance of 20 feet. If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. If you have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at 100 feet.”
Can I Drive Without 20/20 Vision?
The driving standard is 20/40 where the chart letters are twice as big as those on the ’20’ line. If you have to stand at 20 feet away to be able to read this bigger letters, when your normal sight friend can still pick them out from 40ft away, then you have 20/40 vision (the red coloured line on the chart)
Will I Have 20/20 Vision After Laser Eye Surgery?
The answer is YES, but that depends on the clinic and the eye surgeonswho performs the treatment.
For the past 3 years, 100% of Focus patients with typical short-sighted (myopic) prescriptions have achieved 20/20 vision with a single treatment. We do not know of any other clinic that has achieved this success rate.
(Prescriptions up to -8.00 and 2.00 dioptres of astigmatism, binocular vision 6 months post-op – see our full results and statistics.)
The goal of any refractive surgical procedure is to reduce or eliminate your dependence on corrective lenses. However, we cannot, nor can any clinic, guarantee you will have 20/20 vision as a result, although that is indeed the most common outcome our patients confirmed from our own a results audit and published in a professional peer-reviewed journal.
