Eyesight standards query

Does anyone know how the eyesight requirements translate to dioptres? 600 degrees or less in myopia and 200 degrees or less in astigmatism per eye. Is that simply -6 myopia and -2 astigmatism?

I have the same question. If someone could clarify it, it would be most helpful.

Based on my research among Chinese native speakers' online discussions, this is how they will convert "diopters" to "degrees", but I am not sure if Singapore Airlines is looking for an eye exam for glasses or contact lenses. Does anyone have an idea for that?

Also, does anyone know if FAA Operational Color Vision Test (OCVT) and Medical Flight Tests (MFT) results are accepted by CAAS for color vision?
I have a first class medical with a Letter of Evidence (LOE) from FAA with no restrictions except must wear corrective lenses. I have read CAAS' regulation and their requirements are "the applicant shall be required to demonstrate the ability to perceive readily those colours the perception of which is necessary for the safe performance of duties", "an applicant obtaining a satisfactory result as prescribed by DGCA shall be assessed as fit", and "able to readily distinguish the colours used in air navigation and correctly identify aviation coloured lights".
It looks like FAA's exams could be considered valid for color vision? I would appreciate it greatly if someone could share some information on that!

Take a look at this post from another thread.
