What does it mean to have 20 70 vision?
The ratio measurement of vision describes visual acuity, or the sharpness of vision, at 20 feet from an object. For example, having 20/70 vision means that you must be at 20 feet to see what a person with normal vision can see at 70 feet.
What is a 70 20 10 individual development plan?

What does 20/70 vision mean?

The goal of glasses or contacts is to bring a person’s vision to 20/20.
What is the difference between 20/70 and legal blindness?
A person with 20/70 vision can read only down to the third line on the Snellen chart, which represents low visual acuity compared with the norm 2. Legal blindness is defined as 20/200 in the United States, All About Vision reports, so people with 20/70 vision are not considered legally blind 2. The Snellen test determines visual acuity only.
Is 20/60 vision good for blind?
No. 20/60 means you can see something at 20 feet while someone with normal vision can see it at 60 feet. The estimated refractive error is -1. 25 so it fairly mild. To be legally blind, you must have a visual acuity of 20/200 or worse. 20/200 vision.
