If I need a -1.00 prescription for glasses then what is my uncorrected vision?

Question

If it is 20/20 with the corrected what would it be without?

I'm just curious... Thanks

Answer 1

hey!  that's the same as my left eye!  your vision is 20/40.

Answer 2

well lots of factors here...pupil size, etc

but BALLPARKIE 20/40-20/50

Answer 3

ask a doctor but 1.00 is very low so maybe your like 20/30 or 30/40

Answer 4

The best way for a doctor to determine uncorrected vision is to use an eye chart.  Why would one try to guess at this important information?
