Vision. You must have a distant visual acuity of not less than 6/9 in metric (20/30 in feet) in each eye separately with or without the use of correcting lenses. Where the standard of visual acuity can be obtained only with correcting lenses, you may be assessed fit provided that:
1.
you wear such correcting lenses when exercising the privileges of the license or rating applied for or held;
2.
you have a visual acuity without correction in each eye separately of not less than 6/60 in metric (20/200 in feet) and the refractive error falls within the range of plus or minus five diopters (equivalent spherical error); and
3.
you have a spare pair of suitable correcting glasses available for immediate use when exercising the privileges of your license.
