Eye Test and Glasses Vouchers for Screen Users: Tax Exemption Rules 2026/27

Where the exemption comes from

The tax-free treatment of eye tests and glasses is rooted in health and safety law, not tax law directly. Under the Health and Safety (Display Screen Equipment) Regulations, employers must provide, on request, an eye and eyesight test to any employee classed as a display screen equipment (DSE) user — broadly, someone who uses a screen (a computer monitor, for example) as a significant and regular part of their normal work. HMRC's tax exemption simply follows this health and safety obligation: because the test is a legal requirement, not a discretionary perk, its cost is not treated as a taxable benefit for the employee.

What counts as tax-free

Two elements are potentially covered:

1. The eye test itself — always tax-free where it is provided to meet the DSE health and safety requirement.
2. Basic corrective glasses (or contact lenses) needed specifically for DSE use — if the eye test shows the employee needs glasses specifically to use their screen safely and comfortably (as opposed to needing glasses anyway for general life, unrelated to work), the employer can pay for a basic, adequate pair tax-free.

The key distinction HMRC draws is between correction needed because of screen use, versus a general vision problem the employee would need to correct regardless of their job. If the optician's report indicates the prescription is for general use rather than specifically DSE-related, the tax-free treatment may not extend to the full cost of glasses.

Where the exemption stops

Problems arise where an employer pays for something beyond the "basic, adequate" standard:

• Designer frame upgrades or premium lens coatings purely for cosmetic or convenience reasons, beyond what is needed to correct the DSE-related vision issue.
• Glasses for general use that were never really about screen work in the first place.
• Repeat replacement pairs provided more frequently than reasonably needed, without a corresponding eye test showing a change in prescription.

Where an employer's generosity extends beyond the strict health and safety requirement, the excess value is treated as a normal taxable benefit-in-kind, reportable through payrolling of benefits or on the employee's P11D, with Income Tax due from the employee and Class 1A National Insurance due from the employer on that excess amount.

Practical approach for employers

• Only offer to cover the eye test and, where relevant, a clearly defined basic glasses allowance tied to DSE use, rather than an open-ended "designer glasses" perk.
• Keep a simple policy document setting out what is covered (for example, "up to £75 towards basic frames and single-vision lenses where required for DSE use following a qualifying eye test").
• Where an employee wants to spend more than the covered amount on frames or lenses, treat the excess as the employee's own cost, or clearly identify and report it separately as a taxable benefit if the employer chooses to cover it.

Practical approach for employees

• Request your DSE eye test through your employer's normal process if you regularly use a screen for work — this is a legal entitlement, not a favour.
• Ask the optician to note clearly on the report whether the prescription relates to DSE use, since this evidence supports the tax-free treatment if ever queried.
• If you want glasses beyond the basic standard your employer covers, expect to pay the difference yourself, or understand that your employer might report the extra as a taxable benefit if they choose to cover it.
