Just for your info. glasses are not the only criterion for for medical checks.....As said in the previous post, Having glasses is definitely not an issue as long as your distant vision can be corrected to 20/20, Your eyes are checked for a host of other issues.
The best you can do is to get a list of medical requirements of the aviation agency of your country and get yourself checked according to those standards by a known oculist.
