Adrian Chiles needs to know that there are people who can help with his slipping spectacles problem (We can go to the moon – so why can’t we stop my glasses sliding down my nose?, 27 October).
I worked for 25 years as a qualified dispensing optician, and my job, once the optometrist had finished “faffing with the red or green bit”, was to assist a client to choose a frame suitable for the lenses prescribed, which fitted their nose, head width and length to the ears properly, and which matched their cosmetic choice.
