Product Information

The term "20/20" (or 6/6 when measured in metres as used in Australia and New Zealand) and similar fractions (such as 20/60 (6/18), 20/40 (6/12) etc.) are visual acuity measurements. They also are called Snellen fractions, named after Herman Snellen, the Dutch ophthalmologist who developed this eyesight measurement system in 1862. This may be due in part to better printing methods available today vs. those in the 19th century when Snellen was determining the smallest letters a person with “normal vision” should be able to discern. a href="http://visualfractions.com/calculator/improper-to-mixed/what-is-20-6-as-a-mixed-number/">What is 20/6 as a mixed number? To answer these questions, let's take a closer look at how optometrist measure the quality of your vision. Visual acuity, eyesight and vision: What's the difference? Visual acuity

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number. Step 2: Get the new numeratorA good case could be made that "normal" visual acuity today is an ability to identify letters that are a bit smaller than those on the 20/20 (6/6) line of a traditional Snellen eye chart. Although visual acuity testing is very useful to determine the relative clarity of your eyesight in standardised conditions, it isn't predictive of the quality of your vision in all situations. On most Snellen charts, the smallest letters correspond to 20/10 (6/3) visual acuity. If you have 20/10 (6/3) visual acuity, your eyesight is twice as sharp as that of a person with normal (20/20) vision. Is it possible to see better than 20/20 (6/6)? The increasingly larger letter sizes on the lines on the Snellen chart above the 20/20 (6/6) line correspond to worse visual acuity measurements (20/30 (6/9); 20/50 (6/12) ; etc.); the lines with smaller letters below the 6/6 line on the chart correspond to visual acuity measurements that are even better than 20/20 vision (e.g. 6/5; 6/3).

Now let's go through the steps needed to convert 20/6 to a mixed number. Step 1: Find the whole number When we talk about exponentiation all we really mean is that we are multiplying a number which we call the base (in this case 6) by itself a certain number of times. The exponent is the number of times to multiply 6 by itself, which in this case is 20 times. 6 to the Power of 20Vision is a broader term than visual acuity or eyesight. In addition to clarity of sight or simply a description of the ability to see, the term "vision" all interactions between the eyes and the brain, and all neurological processes that take place in the brain to make the sense of vision possible. Visual acuity typically is quantified with Snellen fractions (see "What is 20/20 (6/6) Vision?" below). Eyesight
