What does uncorrected visual acuity mean?
Uncorrected visual acuity (UCVA) is defined as visual acuity measured without correcting refractive errors. Best-corrected visual acuity (BCVA) is examined after correcting refractive errors. The degree of difference between UCVA and BCVA depends on the amount of refractive error .
What uncorrected vision is legally blind?

The term 20/20 means that you can see an object clearly when it’s 20 feet away from you, just like normal. If your vision is 20/100, then viewing an object from 100 feet away is too far for you but fine for others; to see it clearly, you must come within 20 feet of that object.

That means you can see clearly 20 feet away from an object. 20/100 – This is just an example, but those who have a vision type that is 20/100 would have to be 20 feet away from an object that most people can see at 100 feet. The same goes for 20/80, 20/60 and so on when it comes to distance.
What does a person with 20 200 vision see?
That means you can clearly see an object 20 feet away. If you’re legally blind, your vision is 20/200 or less in your better eye or your field of vision is less than 20 degrees. That means if an object is 200 feet away, you have to stand 20 feet from it in order to see it clearly.
What is corrected and uncorrected visual acuity?
When you have an eye examination, the eye doctor measures your visual acuity without glasses or contact lenses, called uncorrected visual acuity. Then, they perform a refraction to see what your visual acuity is with your eyeglass prescription, which is your corrected visual acuity.
What does 20/20 visual acuity mean?
Visual acuity is how clearly you see at a specific distance. For example, when your eye doctor asks you to read letters off a chart during an eye exam, they are measuring your visual acuity. With a measurement of 20/20, the first number indicates the test distance. In other words, how far you are standing from the eye chart.

What causes poor visual acuity?
Refractive errors or neural factors usually cause poor visual acuity. Refractive errors are visual impairments that affect the way light is bent, or refracted, in your eyeball, resulting in decreased visual acuity. Common refractive errors include:
