An eye examination is a series of tests performed to assess vision and ability to focus on and discern objects. It also includes other tests and examinations pertaining to the eyes. Eye examinations are primarily performed by an optometrist, ophthalmologist, orthoptist, or an optician.
The eye examination will be carried out by a registered eye health professional, such as an ophthalmologist, ophthalmic clinical officer, cataract surgeon or ophthalmic nurse, at the county referral health facilities or any other NTSA accredited health facilities, and will entail the following.
- Visual acuity (VA) testing, performed using a standard (Snellen) visual acuity chart, placed 6 metres away in a well-lit room
- An anatomical eye examination, using a torch and ophthalmoscope or slit lamp
- A visual field examination using standard methods, but at least by confrontation method
- Testing of gross ocular motility to rule out diplopia, and fundoscopy for all patients with (or suspected of having) diabetes or glaucoma.
Criteria for visual assessment
Vision is one of the most important sources of information to ensure safe driving. It is important to have good visual acuity and to be able to judge distances so drivers can react appropriately. Applicants should meet the following criteria in order to be certified fit to drive (with spectacles or available correction).
- Two normal eyes which are aligned (no strabismus), freely moving and able to identify images as one (no double vision)
- Visual acuity of at least 6/9 in the best eye
- Visual acuity of at least 6/60 in the other eye
- Normal visual fields.
Developing the guidelines
With technical support from the World Health Organization (WHO), a technical working group (TWG) was formed to develop practical guidelines to implement these legal requirements. The group was led by the Ministry of Health’s Division of Non-Communicable Diseases (NCD) and included representatives of all of the following:
- Medical professionals: both general practitioners and specialists (ear, nose and throat [ENT] and ophthalmic)
- Professional associations and councils
- The National Transport Safety Authority (NTSA)
- The traffic police department
- Owners of public service vehicles (minibuses – also known as ‘matatus’).
During a series of workshops, the group developed feasible technical criteria and a recommended examination process for drivers (involving visual assessment, hearing assessment, and a general health assessment). Here is what was decided in terms of the criteria for visual assessment and the eye examination process.
The road ahead
Finally, before the mandatory assessment is implemented, a wider public discussion is planned and agreement will be sought on guidelines, the assessment form, and the final medical certificate that will be issued before a license can be renewed. The guidelines will be pilot tested before being Gazetted (i.e. become part of Kenya’s law) and will be revised based on trends and new evidence.
Note: These guidelines do not apply to private/small cars.
