Some people, in particular children aged under 16 and those on a low income, may be entitled to help towards the cost of glasses or contact lenses in the form of a NHS optical voucher.
Some people may also be entitled to a NHS optical voucher to help with the cost of repairing or replacing glasses or contact lenses.
Further information on NHS optical vouchers can be found on NHS Inform.
Information on how to submit an application for a HC2 or HC3 certificate under the NHS Low Income Scheme - either using the paper HC1 form or, currently only for some people, online - can be found on the NHS Business Services Authority website.
Additional information for refugees and asylum seekers who may be eligible to receive a NHS optical voucher via a HC2 certificate can be found on a separate area of NHS Inform.
