Pilot vision tests
Hi everybody,
I recently checked out CAAS's eyesight test requirements and i am quite confused (my apologies if my questions seem stupid).
The requirements states that "Distant visual acuity with or without correction shall be 6/9 or better in each eye separately, and binocular visual acuity shall be 6/6 or better. No limits apply to uncorrected visual acuity. Can somebody explain the following:
1) what is binocular visual acuity and does it mean corrected or not corrected?
2) Why is it that they say that Distant visual acuity WITH OR WITHOUT CORRECTION..... but then goes on to say " no limits apply to uncorrected visual acuity? Isn't this a contradiction
3) Last of all, the requirements also says that Where this standard of visual acuity can be obtained only with
correcting lenses, the applicant may be assessed as fit provided that:
(a) such correcting lenses are worn during the exercise of the privileges of the licence
or rating applied for or held; and
(b) in addition, a pair of suitable correcting spectacles is kept readily available
Does this mean that actually as long as you meet the requirements with glasses it is ok?
Sorry for so many questions and thanks a lot!

Medical forum may have been a more appropriate place to post.
Binocular is with both eyes, corrected is OK.
No limits apply to uncorrected means you could theoretically be blind without glasses but as long as with them you meet the standard your OK, no limit to uncorrected. They say with or without correction as if you meet the limits without correction you pass. There is no lower limit though as in the example above.
Yes as long as you meet the requirements with glasses you are OK, there would be a note on your medical stating you must wear lenses (glasses) during flying and have a spare set of glasses with you.
