You can get free glasses on Universal Credit if your household’s take-home pay in your last assessment period was £435 or less, or £935 or less when your award includes a child element or a limited capability for work element. Meeting that test gives you a free NHS sight test and an optical voucher toward the cost of glasses or contact lenses. Earn a little over the line and you may still get partial help through the NHS Low Income Scheme.
The Earnings Thresholds That Decide It
Being on Universal Credit is not enough on its own. What matters is your household’s take-home pay during your most recent assessment period:
- £435 or less is the standard threshold, and it applies whether you earned that amount or nothing at all.
- £935 or less applies if your Universal Credit includes a child element, or if you or your partner have been assessed as having limited capability for work, or limited capability for work and work-related activity.
Take-home pay here means the net income everyone in your household earns after tax, National Insurance, and pension contributions come out. It is not the Universal Credit payment itself. It is the wages sitting alongside it.1NHS Business Services Authority. HWHC – Universal Credit
If you clear that test, the help extends beyond glasses. You also get free NHS prescriptions, free NHS dental treatment, and help with travel costs for NHS treatment.1NHS Business Services Authority. HWHC – Universal Credit
What the Optical Voucher Is Worth
After your sight test, if you need corrective lenses, the optician assigns you a voucher code based on the strength and complexity of your prescription. Straightforward single-vision lenses get the lowest voucher. Bifocals, prisms, and very strong prescriptions get higher ones. Most adults with a standard prescription land on Voucher A (£42.40) or Voucher B (£64.26). Complex prescriptions can go up to £212.40 for the highest standard voucher.2GOV.UK.

Will the glasses actually be free? Often, yes. Most high-street opticians carry a range of frames covered fully by the lower voucher values, so walking out without paying is realistic for many people. If you choose frames and lenses that cost more than your voucher, you pay the difference. If they cost less, the optician keeps the voucher value and you pay nothing, but you do not get change back.3NHS. NHS Voucher Values for Glasses and Lenses
The voucher can be used at any NHS-registered optical provider, so you are not tied to the practice that tested your eyes.
How to Claim at the Optician
Book an eye test at any optician offering NHS services and mention when booking that you believe you qualify for a free test. Bring proof: your most recent Universal Credit award letter showing your earnings and any relevant elements, or a valid HC2 certificate.4NHSBSA: NHS Low Income Scheme. NHS Low Income Scheme The optician will ask you to sign a declaration confirming you qualify. If your sight test shows you need glasses, the voucher is issued straight away and you can choose frames on the spot.
If You Earn Just Above the Threshold
Take-home pay of £440 or £950 does not shut you out entirely. The NHS Low Income Scheme is designed for people whose income is a little too high for automatic full help. You apply with an HC1 form, which you can complete online through the NHSBSA website in about 20 minutes.5NHSBSA. Apply Online for Help With NHS Costs
Based on your income and outgoings, you get one of two certificates. An HC2 gives you the same full help as if you had met the Universal Credit threshold. An HC3 gives partial help: the cost of your glasses is reduced by the difference between your voucher value and the amount your certificate says you must contribute yourself. If that contribution is higher than the voucher value, you end up paying the full price, so the scheme is most useful for people with stronger prescriptions or genuinely tight margins.6NHSBSA. HC3 Certificates (Limited Help With Health Costs)
Certificates expire, and if your circumstances change you can submit a fresh HC1 at any time.
Getting It Wrong Has a Cost
The NHS does check eligibility claims, sometimes months after the appointment. If you sign the declaration saying you qualify and it later turns out your earnings were over the threshold, you can be issued a penalty charge notice on top of what the treatment would have cost. Nobody questioning you on the day does not mean you are safe.
Before your appointment, look at your latest Universal Credit statement and check the take-home pay figure for your last complete assessment period against the £435 or £935 threshold. If you are close to the line, applying for an HC1 certificate first removes the guesswork, because the NHSBSA will tell you exactly what you are entitled to.7NHS.

Other Routes If Universal Credit Does Not Cover You
If your earnings put you over the threshold this period, you may still qualify for free NHS sight tests and vouchers on other grounds. That includes being under 16, or 16 to 18 in full-time education; being 60 or over; being diagnosed with diabetes or glaucoma; being 40 or over with a parent, sibling, or child diagnosed with glaucoma; being identified by an ophthalmologist as at risk of glaucoma; being registered partially sighted or blind; or being on Income Support, income-based Jobseeker’s Allowance, income-related Employment and Support Allowance, or Pension Credit Guarantee Credit.8National Health Service (NHS).
