Is 0.9 cycle equal to 1

Is 0.9 cycle equal to 1

Equal to 1, this is a high school proof
There are two ways to prove that the first one is better. If you think 1 / 3 is 0.33 cycle, 2 / 3 is 0.66 cycle, 3 / 3 is 0.99 cycle, then 3 / 3 = 0.99 cycle, and obviously 3 / 3 = 1, then 1 = 0.99 cycle
The second proof is more professional, which is not clear on the Internet,

How many degrees is vision 0.2 equal to?

A little more than 500 degrees

How many degrees of vision is 0.6?

1. There is no absolute relationship between eyesight and diopter. Diopter and naked eyesight are not proportional. For example, some people with myopia of 500 degrees can see 0.2 when they look at the far vision chart, while another person with myopia of 300 degrees can only see 0.1 when they look at the far vision chart. At the same time, some people with hyperopia of 300 degrees can also see 0.2 when they look at the far vision chart
2.0.1-1.5 is the expression of visual acuity
3. The power is detected by optometry or computer optometry

How many degrees is naked eye vision 4.5 (0.3) equivalent to?
