Oh dear. We have another disappointed candidate.
The requirement for perfect vision at the start of your career is laid down by the companies. It doesn't apply if you are going to pay for your own ATPL training course which costs about HK$600,000. I don't think that it is unreasonable for a company to set the standards high when they are putting their money forward.
Most airlines are the same throughout the world - try to get a scholarship for BA with glasses - no can do!
In the far east it is even more applicable due to the physiological changes are different in caucasians compared to Asians. Just a fact of life - the eye finishes developing later for Asians so the risk of failing later in life is greater when you are only looking at someone 18years old.
Best of luck - try instructing abroad first, as a friendly suggestion to an obvious enthusiast.
