Is 6-9 6-18 vision considered poor?

Answer 1

Vision of 6/9 isn't too bad but 6/18 is quite poor (although I have seen worse!). It is important to remember that the UK and the US use different units of measurement for visual acuity. Feet in the US and Metres in the UK. 20-20 is the same as 6/6. -------------------------------------------------------------------------------- Perfect vision is 20-20

. Your numbers are very much under that.

Answer 2

A 6/9 or 6/18 vision is considered relatively good for distance vision, where a person can see at 6 meters what a person with normal vision can see at 9 or 18 meters, respectively. However, it is not considered perfect and may be indicative of some degree of impairment or refractive error. It is best to consult an eye care professional for a proper evaluation and treatment if needed.
