Discussing functional vision during a consultation

Functional Vision Questionnaire

How your vision affects daily life — the questions we ask, so you can think them through before we speak.

Why functional vision matters

Acuity measured on a chart tells only part of the story. Two people with the same recorded acuity can have very different experiences of daily life, depending on contrast sensitivity, glare tolerance, adaptation to changing light, and the size and position of any blind spots.

Functional vision describes what you can actually do — read a menu, recognise a face across a room, drive at dusk, find a step in shadow. It is often the measure that matters most to patients, and it is a large part of what we track over the course of care.

The questions below are the ones we work through during a consultation. Thinking about them beforehand tends to make that first conversation considerably more useful.

Questions to consider before your consultation

Reading and near work

Can you read normal print comfortably, and for how long before it becomes tiring?
Do you need brighter light than you used to for the same task?
Do letters or lines appear broken, wavy, or missing in places?

Distance and recognition

Can you recognise a familiar face across a room?
Are road signs or television subtitles harder than they were a year ago?
Have you noticed a difference between your two eyes?

Light, contrast, and glare

How long does it take your eyes to adjust when you move from bright light into a dim room?
Do headlights, sunlight, or screens cause discomfort or halos?
Is low-contrast detail — a grey step, a pale kerb — harder to judge?

Movement and orientation

Do you bump into objects on one particular side?
Has your confidence walking on uneven ground or stairs changed?
Have you stopped driving at night, or stopped driving altogether?

Comfort and change over time

Do your eyes feel dry, gritty, burning, or tired by the end of the day?
Over what period did you first notice a change — weeks, months, or years?
Which single activity would you most like to be able to do again?

There is no score and nothing to submit. Bring your answers — along with your current diagnosis, recent imaging or field tests, and a list of your medications — to your consultation.

This questionnaire is for reflection and consultation preparation only. It is not a diagnostic instrument and does not replace examination by a qualified eye care professional. If you experience sudden vision loss, sudden severe eye pain, or flashes and floaters of new onset, seek urgent ophthalmic care.
