NHS Glasses Vouchers Explained

An NHS optical voucher (NHS glasses voucher) is a certificate issued by your optician after an eye test. It provides you with a contribution that can be put towards the cost of prescription glasses or contact lenses. This can be used towards glasses at any optician that accepts NHS optical vouchers.

The voucher does not give you free glasses in most cases, it provides a contribution towards the cost. Whether your glasses are free depends on whether the voucher value covers the full price of the frames and lenses you choose. For many children, and adults with lower prescriptions, vouchers often cover the full cost of basic frames.

Important: NHS optical vouchers must be used at a registered participating optician

Not all optical retailers accept NHS optical vouchers. As of 2026, NHS optical vouchers cannot be used on most online glasses websites, including Direct Sight. They must be redeemed in person at an optician registered to process NHS optical claims. These include opticians such as Specsavers, Boots Opticians, Vision Express, and most independent opticians.

According to NHS guidelines, the following groups are entitled to a free NHS eye test voucher in UK.

(Eligibility differs in Scotland, where NHS eye tests are free for all residents, and may also differ in Wales and Northern Ireland, check with your local health board.)

Qualifying for NHS free eye tests does not automatically mean you will receive an NHS optical voucher for glasses. Optical vouchers are available to most, but not all, people who receive a free NHS eye test. You will be entitled to an NHS optical voucher if you meet any of the criteria above. With the exception of people aged 40 or over who qualify only because of a family history of glaucoma.

The NHS optical voucher for glasses is issued at the end of your eye test as a yellow GOS3 form.

Make sure your optometrist has signed it and included their ophthalmic list number, without this, it cannot be accepted elsewhere.

NHS optical voucher values are set by the government and have remained unchanged since April 2024. There are ten voucher bands, labelled A to J, based on the strength of your prescription. The stronger or more complex the lenses required, the higher the voucher value.

Source: NHS optical voucher values (April 2024, march 2026, confirmed unchanged from April 2025 per GOV.UK). Bands F, J cover progressively more complex prescriptions up to a maximum of £233.56. Complex lens vouchers are separate and worth £15.81 (single vision) or £40.57 (bifocal) for prescriptions of ±10 dioptres or more.

If the glasses you choose cost more than the voucher value, you pay the difference. If they cost less, the difference is not refunded to you in cash, you simply pay nothing.

NHS optical vouchers are accepted at any optician that is registered to make NHS optical claims. You are under no obligation to use it at the same practice that carried out your eye test. The voucher is valid for a limited period from the date of issue, typically six months. If it expires before use, you may need a new eye test to obtain a replacement.

Currently, you can not use NHS optical voucher for glasses online at Direct Sight. This is an industry-wide limitation, not specific to Direct Sight. It applies to most online prescription glasses websites in the UK.

Direct Sight does not accept NHS optical vouchers. If you have an NHS optical voucher and want to use it, you should take it to a participating optician. Your local Specsavers, Boots Opticians, Vision Express, or independent practice will be able to help.

However, it is worth pausing to consider the numbers, depending on your prescription and what you are looking for. Our prices may still represent better value even without applying a voucher.

Here is why:

• Our prescription glasses start from £9.00 including lenses. Well below the value of even the lowest NHS voucher band (£42.40)
• A Band A NHS voucher (the most common) covers glasses up to £42.40. Many of our frames with prescription lenses cost less than this outright
• Our prices are all-inclusive, with no surprise extras at checkout
• You can order a spare pair, different styles, or prescription sunglasses at a fraction of the cost of one high street pair

If your voucher value is £42.40 (Band A) and you would otherwise spend that at a high street optician . Choosing the cheapest frames to avoid a top-up. You may find that ordering from Direct Sight without the voucher gives you more choice and similar or lower total cost.

For higher-band vouchers or complex prescriptions in-person dispensing advice maybe beneficial. Using your NHS voucher at a participating optician may still be the right choice. We encourage you to compare and decide what works best for you.

If you are entitled to a free NHS eye test, the most important thing is to use it, regardless of where you decide to buy your glasses. Your eye test is a full health check, more than a prescription update.

Optometrists can detect early signs of conditions including glaucoma, cataracts, age-related macular degeneration, diabetes, and high blood pressure, many of which develop without obvious symptoms.

The NHS recommends most adults have an eye test at least every two years. Children and those with certain conditions may need more frequent tests. Your optometrist will advise you on the right schedule for your eyes.

Once your eye test is complete, your optometrist is legally required to give you a copy of your prescription. You can take it to any optician or online retailer to have your glasses made. You are never obliged to buy from the practice that tested you.
