Eye test costs UK: who gets a free NHS sight test and what the rest pay for

This guide explains who pays for an eye test in England and what the money covers. It quotes no private test prices, because Whito has not yet collected them and will not invent them; opticians publish their own, dated on their own pages. The eligibility rules below are the NHS’s, read 5 October 2026.

Who gets a free NHS sight test

Large groups qualify, among them: under 16s, under 19s in full-time education, people aged 60 or over, people with diabetes or glaucoma, close relatives of glaucoma patients aged 40 plus, people registered sight-impaired, and people on qualifying benefits. The full list is on the NHS website, and the optician checks eligibility when you book. If you are in a qualifying group, the test itself costs you nothing.

Optical vouchers: help with the glasses, not just the test

Some groups, children and people on qualifying benefits among them, also get NHS optical vouchers towards glasses or contact lenses. Voucher values are set nationally by prescription strength, and the voucher pays that amount off any pair, so a voucher can cover a basic pair entirely or part-pay a dearer one. Ask the practice to show the voucher value on the receipt; it is your money, visibly applied, or not.

What a private test is actually buying

A sight test is a clinical examination, prescription plus eye-health checks, performed by a GOC-registered optometrist. Practices publish their own test prices, and the cheap test subsidised by glasses sales is this trade’s standard model: the test price is the door, the frames are the business. Knowing that, judge a practice by the examination and the prescription, then buy frames wherever suits, which the prescription they must give you makes possible.

The add-on scan question

Many practices offer OCT or retinal photography as a paid add-on. These scans are genuinely useful clinical imaging, and they are also upsold hard. A fair practice tells you what the scan is for in your case and what it costs before the chair reclines, not after.

The check that frames all of it

Optometrists and optical businesses are registered with the General Optical Council, and the registers are public. Whito’s guide to checking an optician on the GOC register covers it in two minutes; the price conversation belongs only at practices that pass.
