Am I allowed with glasses? And if yes how big is the maximum size?

Hi Gabriel, yes you can join up wearing glasses. However you would have to wait to go through the medical examination to ensure your eyesight is of the required standard.

Gabriel, once you have attended your Army Brief at your chosen armed forces careers office, they will give you something called an OPTO form for you to take to your opticians. Once your optician has complete it, if you then return it to the careers office where they will upload it to be reviewed by the National Recruiting Centre.
