asked Her Majesty's Government:How many portable prescriptions for spectacles have been processed by unregistered opticians' dispensaries since the relevant provisions of the Health and Social Security Act 1984 came into force; and how many unregistered dispensaries are currently operating?

I regret that this information is not available. However, nearly 21,000 National Health Service vouchers were used to obtain spectacles from unregistered suppliers during the 12-month period to 30th June 1987.
