Question: When the eye doctor said that my vision was measured at 20/400, what did he mean!?
More specifically, what do the numbers mean and what causes me to be so nearsighted!?Www@Answer-Health@Com


Answers:
That simply means you have to be at 20 feet to see an object that a normal eye can see at 400 feet!.

Your eyes have just developed that way , genetics mostly!.

That would be your UNcorrected vision!. You are most likely 20/20 with your glasses or contacts on!.Www@Answer-Health@Com
