Medical Faxes And Confidentiality Statements Are Eye Test Prescriptions In The UK Treated With The Same Confidentiality As Medical Records?

Are eye test prescriptions in the UK treated with the same confidentiality as medical records? - medical faxes and confidentiality statements

I am currently in Peru and want a new pair of glasses, but I have my eye exams in order for me. I wanted to ask my mother for a copy of the fax and my results. Is this possible or is there a law prohibiting their optical this information to other persons to disclose than me? If it is a law, what can I do to get a copy of my recipe in Peru?
