The Opticians Act of 1989, amended in June 2005 regulates the sale of contact lenses in the United Kingdom. The act establishes that contact lens vendors may only supply you with the lenses prescribed and fitted by your optician and as such may require you to provide a signed and dated copy of your precription.
If you cannot provide a copy of your prescription suppliers are obliged to contact your optician prior to processing your order. Some of the providers indexed by lensfinder.co.uk are not based within the United Kingdom and as such may be subject to different rules and regulations however lensfinder.co.uk strongly advises that you apply due diligence and obtain regular checks on the health of your eyes. Lensfinder.co.uk strongly recommend that you purchase only those lenses for which you have a valid prescription and that in all cases you report any change in the state of your vision or condition of your eyes immediately in addition to obtaining regular checks as recommended by your practitioner.
