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.

No. Not really. "Normal" vision is around 20/20 or 20/30. Having 20/60 means that you need to be 20 feet away from an object rather than a "normal" person who can see that object at 60 feet. At 20/60 you should still be able to function with everyday life and only need glasses to drive or to read a blackboard at school. 20/60 is only a mild impairment. 20/30 to 20/60 is considered mild vision loss, or near-normal vision 20/70 to 20/160 is considered moderate visual impairment, or moderate low vision 20/200 to 20/400 is considered severe visual impairment, or severe low vision 20/500 to 20/1,000 is considered profound visual impairment, or profound low vision less than 20/1,000 is considered near-total visual impairment, or near total blindness

No, you are not yet an adult. You must reach the age of majority, which is 18.
In the term "20/20 vision" the numerator refers to the distance in feet from which a person can reliably distinguish a pair of objects. The denominator is the distance from which a person with standard VA (that is, with 20/20 vision) would be able to distinguish them-the distance at which their separation angle is 1 arc minute. The metric equivalent is 6/6 vision where the distance is 6 meters. Twenty feet is essentially infinity from an optical perspective (the difference in optical power required to focus at 20 feet versus infinity is only 0.164 diopters). For that reason, 20/20 vision can be considered nominal performance for human distance vision; 20/40 vision can be considered half that acuity for distance vision and 20/10 vision would be twice normal acuity. The 20/x number does not directly relate to the eyeglass prescription required to correct vision; rather an eye exam seeks to find the prescription that will provide at least 20/20 vision.
the fact family of the numbers 3, 6, and 18 is: 3 x 6 = 18; 6 x 3 = 18; 18 ÷ 3 = 6; 18 ÷ 6 = 3
No, 18 is a multiple of 6. 6 is a factor of 18.
