A relative or carer can arrange an eye test for a person with dementia by finding a suitable optometrist, contacting the practice directly and explaining the support required. If attending a practice is not practical, ask whether the person qualifies for a home or residential-care visit. Booking the appointment does not automatically give the carer authority to consent to treatment. The optometrist must involve the person, assess capacity when consent is needed and adapt the examination to their abilities.

Finding and contacting an optometrist
In England, use the NHS Find an NHS sight test service to search by postcode. Contact the practice directly rather than trying to make the person manage the arrangements alone. Explain that you are booking on behalf of someone with dementia.
Ask whether the practice can accommodate their communication, mobility and cognitive needs before confirming the appointment. When booking, cover these points: The College of Optometrists advises discussing these needs in advance so the optometrist can plan an appropriate examination. It also recommends choosing the person's best time of day and preferred setting.
- The person's dementia diagnosis and level of cognitive impairment.
- Their preferred setting and best time of day.
- How they usually communicate and understand instructions.
- Whether they are likely to become tired, anxious or unable to cooperate.
- Who will accompany them and what support that person can provide.
Choosing the right person to attend
An informed relative or main carer should attend the appointment and remain involved throughout. This person can reassure the patient, explain unfamiliar instructions and provide relevant background.
A paid care worker can accompany the person, but they should know them well enough to help effectively. Someone unfamiliar with the person may not recognise their usual communication style or know whether a response reflects poor vision, confusion or distress. Before the visit, the companion should be ready to explain:.
- How the person indicates agreement, discomfort or uncertainty.
- Whether short instructions, demonstrations or extra response time help.
- Any recent changes noticed in their vision or everyday behaviour.
- Whether glasses are used and how consistently they are worn.
When to request a home eye test
A relative or main carer may request a domiciliary sight test—an eye examination provided where the person lives. Ask local practices whether they offer home visits and can adapt testing for dementia or communication difficulties. In England, an NHS-funded mobile sight test may be available if the person already qualifies for a free NHS sight test and cannot leave home or residential care unaccompanied because of physical or mental illness or disability.
The NHS explains the conditions for free sight tests and mobile services. Do not assume that dementia alone guarantees a funded home visit. Describe why the person cannot attend without assistance, then ask the practice to confirm eligibility and availability.
Consent and decision-making capacity
Dementia does not automatically mean that a person lacks capacity. Capacity means being able to make the particular decision in question, and it must be considered at the relevant time. Supporters should presume capacity and help the person understand and communicate. Simple explanations, an appropriate time of day and familiar support may help them participate in the decision.
When consent to an examination is required, the healthcare professional determines whether the person has capacity. If the person lacks capacity, they must still be involved as far as possible, and any decision must be made in their best interests. A registered health-and-welfare attorney may make medical-care decisions only after the person who appointed them lacks capacity. The attorney may need to show the lasting power of attorney document, must follow any restrictions in it and must act in the person's best interests, as set out in the government's health and welfare attorney guidance.
What happens after the appointment
The NHS recommends an eye test every two years, or sooner if an optometrist advises it. Keep a record of the examination date and any recommended follow-up so future appointments do not depend on the person remembering to arrange them. An optometrist can identify conditions including cataracts, glaucoma and macular degeneration.
If further investigation is needed, the optometrist can refer the person to an appropriate service. Ask the practice to explain the outcome in a form the person can understand. Before leaving, confirm any next appointment, referral or change in glasses with the person and the relative or carer responsible for helping them follow the plan.
