NHS optical vouchers — free eye tests, sight tests and help with glasses
In short. NHS sight tests are free in Scotland and Wales for every resident. In England and Northern Ireland a sight test is only free for the under-16s, full-time students under 19, people aged 60+, those receiving qualifying benefits (Income Support, Income-based JSA, Income-related ESA, Pension Credit Guarantee, Universal Credit with the relevant income test), holders of an HC2 or valid HC3 certificate, registered Sight Impaired or Severely Sight Impaired, glaucoma sufferers and certain at-risk groups. NHS optical vouchers help with the cost of glasses or contact lenses for the same eligible groups; values are set by prescription complexity and reviewed each April by the NHS Business Services Authority.
Optical voucher rules differ markedly across the four UK nations, and the value of help with glasses depends on the strength of prescription, not the chosen frames. Understanding which voucher applies — and the HC1 process for income-based help — keeps real money in households where eyesight costs are unavoidable.

NHS optical voucher values 2025/26
Voucher value depends on the complexity of the prescription, not the frame chosen. Vouchers run from type A (simple single-vision prescription, lowest value) up to type H and special complex-lens vouchers (high-power and very complex prescriptions, highest value); separate small-frame supplements apply to children. The full current table is published by the NHS Business Services Authority and updated each April — readers should check the live page before relying on a specific figure.
The voucher can be used towards any glasses or contact lenses dispensed by an NHS-registered optician. If the chosen frames cost more than the voucher value, the patient pays the difference. There is no refund if the chosen glasses cost less than the voucher value.
HC1 / HC2 / HC3 — help on low income grounds
Households not on the qualifying benefits but with a low income can apply on form HC1 (NHS Low Income Scheme). HMRC and the NHS Business Services Authority assess income, capital and outgoings against the qualifying levels. The outcome is either an HC2 certificate (full help with NHS charges including a sight test and voucher towards glasses) or an HC3 certificate (partial help, with the amount the holder must pay shown on the certificate).
Certificates are normally issued for 6 to 12 months and must be renewed. They cover the holder, their partner and any dependent children listed.
Scotland, Wales and Northern Ireland
In Scotland, NHS sight tests are free for every Scottish resident, performed at any approved optician — the broadest entitlement in the UK. In Wales, NHS sight tests are free for the same groups as England plus some additional at-risk categories under the Wales Eye Care Service. In Northern Ireland, free sight tests follow the same eligibility rules as England.
Optical voucher values for glasses and contact lenses are broadly comparable across the four nations but are set separately by each NHS body and reviewed each April.
FAQ
- How often can I have a free NHS sight test?
- Generally every two years for adults, every year for children under 16, every year from age 70, and more often if a clinician has advised it (for example after a referral or for diabetes monitoring). The optician will tell you when you are next due — booking sooner generally means paying privately.
- Can I use an NHS voucher towards designer or branded frames?
- Yes, at any NHS-registered optician. The voucher value is fixed by prescription complexity; if the frames cost more than the voucher, the patient pays the difference. Some opticians stock a range of frames at exactly voucher value so the patient pays nothing.
- Does Blind Person's Allowance entitle me to a free sight test?
- Blind Person's Allowance is a tax allowance, not an NHS entitlement. However, anyone registered as Sight Impaired or Severely Sight Impaired automatically qualifies for free NHS sight tests in England (and is already entitled in Scotland, Wales and Northern Ireland).
- What if I'm housebound — can I still get a free NHS sight test?
- Yes. The NHS funds 'domiciliary' sight tests delivered at home for patients who are unable to leave home unaccompanied because of physical or mental illness or disability. The same eligibility criteria apply.
