If you run a business in the UK and your staff spend their days glued to computer screens, you’ve got to look after their eyes. Yes, it’s a legal duty on you.
But there are a few sneaky traps that many employers fall into. These mistakes can turn a simple benefit into a real headache, usually involving unexpected tax bills!
If you’re a business owner, in HR or just curious, this guide is for you.
Here, we’ll cover:
- 7 Traps When Providing Eye Tests for Employees
- How to Avoid those traps, and
- Much More..
First off, let’s quickly cover why this is a thing and who it applies to.

Do Employers Have To Pay For Eye Tests UK?
Yes, they do. In the UK, the Health and Safety (Display Screen Equipment) Regulations 1992 state that employers must protect the health of staff who use computers a lot. This includes their eyes. The goal is to prevent eye strain and fatigue. Also the discomfort associated with screen work.
Who Is Covered?
Basically anyone who spends an hour or more at a stretch on a computer, laptop or tablet as part of their job.
It does not matter if they are in the office. Working from home. Or on a hybrid setup. If screens are a big part of their work, this applies.
What Do I as an Employer Have To Provide?
If a qualifying employee asks for an eye test, you are legally obliged to provide and pay for:
- A full eye test with a qualified optician.
- Glasses if the test shows they need special ones just for screen work. (You don’t have to pay for their everyday glasses.)
That’s the basic deal. Now, let’s look at where employers usually stumble.
The Tricky Part: Method of Provision
This is usually where things go wrong for employers.
Eye tests can be tax free but only when they’re provided in the right way. HMRC cares less about the cost and more about how the test is arranged and paid for.
Scenario 1: Employer Arranges and Pays for the Test
- How it works: The company sets up an account with an optician, buys vouchers or simply receives an invoice in the business name. The employee attends the test and the optician bills the company directly.
- Tax position: HMRC treats this as the employer meeting a health and safety duty. The test is fully exempt from Income Tax and National Insurance.
- P11D requirement: None. No benefit is created for the employee. Therefore, nothing needs to go on a P11D.
This is the cleanest and safest method. Most accountants recommend this approach.
Scenario 2: Employee Arranges the Test, and the Employer Pays
- How it works: The employee arranges the appointment, attends, hands over the invoice, and the company then pays the optician directly.
- Tax position: This looks harmless but HMRC may view it as the company clearing an employee’s personal bill. That can turn it into a taxable benefit. Why? Because the employee technically “owed” the optician before the company stepped in.
To be fully compliant, most accountants recommend avoiding this method and sticking to Scenario 1 to ensure the Exemption for Eye Tests applies clearly.
Scenario 3: Employee Arranges the Test and is Reimbursed
- How it works: The employee pays for the test upfront and claims the cost back through expenses.
- Tax position: HMRC is very clear on this one. If the company reimburses the employee, the payment becomes a taxable benefit. The cost is treated as a personal expense the company has refunded. And not a workplace health and safety provision.
This is the method that causes the most trouble during reviews and audits.
- P11D requirement: The full amount must be reported and it becomes subject to Income Tax and National Insurance.
Quick Note: What Is a P11D?
A P11D is a form employers submit to HMRC when an employee receives a taxable benefit. It is like a list of extra perks or benefits. If something lands on a P11D, the employee may owe extra tax. And the employer may owe extra NICs.

The Real Traps Employers Fall Into (And How To Avoid Them)
Many businesses think providing eye tests is simple. Someone asks, you approve of it, job done!
But that’s not the case.
Below are the traps to avoid if you want a smooth and compliant process.
Trap 1: Assuming Eye Tests Are Optional
Some employers believe eye tests are just a nice-to-have or part of a general wellbeing programme. This is not correct.
If an employee is a screen user and requests it, the employer must pay for the eye test. Ignoring the request is actually breaking the Display Screen Equipment (DSE) rules.
Trap 2: Offering Eye Tests Only to Office Staff
It’s easy to forget that screen use isn’t just in the office. Many companies accidentally exclude:
- remote workers
- hybrid staff
- part timers
- employees working on tablets or POS screens
If they regularly use a screen, location doesn’t change the requirement. Overlooking this can land your company in non compliance without even realising it.
Trap 3: Not Understanding the Exemption for Eye Tests
Some employers confuse the rules and incorrectly treat eye tests as medical benefits.
But in reality, there is an Exemption for Eye Tests when the test is required under DSE regulations. That means the employer can pay for it without triggering a taxable benefit for the employee.
Trap 4: Paying for Eye Tests in the Wrong Way
This trap creates huge confusion and it is usually related to the two common routes, which we have already discussed:
Employer arranges and pays for the test
This is simple and rarely causes problems. The employer sets up a provider and pays directly.
Employee arranges the test and the employer pays
This model causes trouble when there is:
- no clear reimbursement policy
- no cap on cost
- no requirement for a standard sight test only
- poor documentation
Without a clear policy, a business can end up paying for enhanced tests or personal extras that are not required under the law.
A simple fix is to set a cost limit and make the employee submit proof of a standard sight test only.
Trap 5: Not Providing Tests at “Regular Intervals”
Many employers provide one test and then forget about it. But the rules say tests should be repeated whenever the optometrist recommends it.
Not following this advice is a compliance tripwire.
Trap 6: Forgetting About Specs for DSE Work
The employer must also pay for basic glasses if an employee needs them solely for screen work. This is not the same as paying for personal glasses.
A frequent mistake is reimbursing the full cost of expensive frames. This is not required and often leads to unnecessary expense.
Trap 7: Poor Communication
Some companies have a policy on eye tests but never actually tell anyone about it. So people end up booking tests themselves, picking expensive options or assuming everything will be paid back or not even asking at all.
It’s easy to avoid this trap. How? Just tell everyone how it works!
A simple note or email explaining whether the company arranges and pays, or whether they get reimbursed can clear up a lot of confusion.
You can use the HSE website’s DSE guidance as a clear, official reference point for your internal communications.
The Main “Traps” Explained Simply
To avoid problems, especially with taxes, follow these two simple rules:
| The Trap (Mistake) | The Solution (Correct Way) |
| Reimbursing the employee: The employee pays the optician and you give them the cash back later. This is a taxable benefit (extra tax must be paid). | Pay the optician directly: Set up an account with an optician, use a voucher scheme, or pay the optician’s invoice directly. This is not taxable. |
| Paying for general glasses: You pay for glasses that the employee uses for everything (reading, driving, watching TV, etc.). | Only pay for “DSE-only” glasses: The optician’s report must confirm the glasses are specifically for the working distance of their screen. You are only required to cover the cost of a basic pair of these work-only glasses. |
By paying the optician directly and only covering the cost of glasses needed solely for screen work, you comply with the law. And avoid unexpected tax bills.
How Often Should Eye Tests Be Offered
There isn’t any strict “every X months” rule written into the law. But the usual guideline is every two years.
Some people might need one earlier if an optician advises it or if they start noticing symptoms linked to screen use such as headaches or blurred vision.
And just to clear things up, this isn’t only for office employees. This applies to everyone who regularly works with screens. This includes remote employees, hybrid staff, and in some cases even contractors, depending on their agreements and how often they use display equipment.
Exemption For Eye Tests: What You Can And Cannot Skip
A lot of employers think they’re exempt because someone already wears glasses or because the job isn’t “office work”. That’s not how the rules work.
Exemptions are limited and only apply when someone:
- Isn’t classed as a DSE user
- Only uses screens occasionally
- Recently had an eye test and isn’t due for another one yet
But if an employee is a genuine DSE user and asks for an eye test, you’re legally expected to provide it.

The Bottom Line
Eye tests for screen users aren’t optional. They’re a legal requirement. And things only get complicated when the rules are misunderstood.
Once you know who qualifies, what you need to cover and what HMRC expects, the whole process becomes simple.
The easiest approach is to organise and pay for the test directly, keep basic records, and make sure staff know what’s covered.
