Vision Question?

Question

To become a pilot here in canada you are allowed to wear glasses, but they said the applicant has to possesses a visual acuity without correction in each eye separately, not less than 6/60 (20/200) and the refractive error falls within the range of ± 3.0 diopters (equivalent spherical error);
what does this mean? i know that with glasses my prescription is about -3.25 how can i find out what is it in terms of 20/ ?

Answer 1

This isn't exactly answer to your question, but there are some exercises that can improve your vision. They work, but you must practice them every day persistently.

I used to be short sighted (-1.00 D) with small astigmatism and was able to completely improve my vision with these exercises within a few months.

Hope this helps!

Best regards,

Answer 2

The -3.25 you mentioned is the power of your glasses in diopters, which is slightly outside the acceptible range of +/- 3.0 diopters regardless of the 20/200 limit. Note: the results of the eye exam are a little bit subjective as to when something is in focus or not, and you are right on the borderline of passing/not passing, so you might get retested and come out as -3.0 or even -2.75 which would pass. The problem is, you would be very close to the cut-off limit; and they might have a rule that, once you are a pilot, if you vision gets worse than 20/200 uncorrected maybe they don't let you fly any more (I don't know for certian, you should check on this).
