Visual acuity
We measure central visual acuity in each eye, with or without your usual glasses or contact lenses as required.
Reliable assessment of visual functions
Eye examination reports for driving and recreational boating licences
An ophthalmological assessment involves more than reading letters on a chart. Depending on the licence you need and the purpose of the assessment, we test several aspects of vision that help you navigate safely on the road or on the water.
Understanding the procedure
The examination you need depends on the reason for your visit.
A basic vision test is different from a full ophthalmological assessment. A more detailed examination may be required if you do not pass a mandatory vision test, there are concerns about your eyesight or you are applying for certain licence categories.
Please bring the authority’s request or the form you need completed. This lets us tailor the examination to the legal requirements and avoid missing tests or an incomplete certificate.

Used where needed
Which visual functions can be tested?
Not every licence requires the same tests. The applicable regulations and purpose of the assessment determine what is needed.
Visual field
Perimetry checks whether you reliably detect light in the relevant parts of your visual field.
Low light and glare
Contrast and glare tests show how reliably you see details in dim light or with light shining towards you.
Binocular vision
Depending on the assessment, we check alignment, double vision, depth perception, eye movement and how the two eyes work together.
Step by step
That's how the appointment goes.
Bring the full assessment request and the correct glasses or contact lenses.
Checking your documents
We clarify the licence category, reason for assessment, authority’s requirements and form needed.
Measuring visual values
Visual acuity and current correction are measured using standard methods. Further tests follow according to the requirements.
Examine the eyes
Where needed, we assess alignment, the front of the eye, lens, optic nerve and retina.
Interpreting the result
We record the results according to the applicable requirements and discuss any medical findings separately.
Understanding the results
An assessment answers a specific question.
We assess measurements together, checking whether the required visual functions are met and whether corrective lenses, conditions or follow-up need to be considered.
An ophthalmological report does not replace the licensing authority’s decision. The authority uses the documents submitted to decide on a licence, renewal, conditions or further steps.
Well prepared
How to prepare for your visit
- Identity card or passport
- existing glasses and, where appropriate, contact lenses
- Official letter or required form
- Previous eye examination reports for known conditions
Frequently asked questions
Clear, concise answers.
How long is a certificate valid?
This depends on the type of certificate and its legal basis. We record the examination date; the relevant authority can confirm the deadline for your application.
Can I be examined with contact lenses?
Often, yes. Still bring your glasses and any contact lens details. Some assessments require testing with the correction you normally use.
Can I drive myself after the appointment?
Usually, if your pupils have not been dilated. If they have, or your vision is otherwise affected, drive again only when you can see safely and meet the legal requirements.
