Thank you to everyone for your advice.
I'm going to do a test flight to see how I handle that. Then I'll do the physical. Once successfully completed there's an ATPL integrated course in Valencia, Spain. I live just 2.5 hrs drive from there. It'll take me 14 months to complete.
The course dosen't include type ratings. They told me that unless you know which airline you can get a job in and what type they use, it's not worth investing the money, that the airlines usually will give you the training.
Before I go to any trouble I wear glasses for driving. This may be a stupid question but does one need perfect eyesight? Have 0.75 in each eye.
