CASA Aviation Eye Examinations

Obtain aviation eye examination approved by Civil Aviation Safety Authority

The Australian Civil Aviation Safety Authority (CASA) regulations require that all pilots with a Class 1 commercial licence and all air traffic controllers with a Class 3 licence must have an aviation eye exam performed by either a designated aviation credentialed optometrist (CO) or ophthalmologist (DAOs).  

In the field of aviation, good visual function is necessary for the safe performance of aviation activities: pre-flight checks, take-offs, navigation, landings and the proper use of displays, dials, gauges, and maps in modern cockpits.

The eye exam is a required part of the medical certificate for a Class 1 or Class 3 licence. The pilot eye tests and exams must be performed by a designated aviation credentialed optometrist (CO) or ophthalmologist (DAO).  


CASA-credentialed optometrists

Credentialed Optometrists (COs) are trained to perform vision and eye exams for Class 1 and 3 medical certificates. They are formally recognised as trained occupational vision experts. All applicants for Class 1 and Class 3 licences can be assured that the COs have the essential skills to provide the proper vision assessment, exam and vision care to critical staff in the aviation industry.

COs are required by CASA to maintain certain clinical competencies, including familiarity with the aviation standards and CASA’s medical record system and statutory declarations.


Key components of CASA aviation eye exams

What’s included in a pilot eye test:

  1. Visual Acuity Tests:

    1. Distance Vision: Pilots must achieve a minimum distance visual acuity of 6/9 in each eye and 6/6 binocularly (with both eyes) with or without corrective lenses.

    2. Near Vision: Pilots must be able to read N5 vision at 30-50cms (control pad distance) as well as N14 vision at 1m.

  2. Binocular Vision: Assessing the eyes abilities to work well together to maintain fixation and depth perception

  3. Peripheral vision: Assess the ability to detect objects outside the direct line of sight. This is done via monocular or binocular visual field assessment.

  4. Colour vision Assessment: candidates must demonstrate adequate red-green colour discrimination for safe aviation operations. Those with red-green colour vision deficiency detected with Ishihara, and are class 1 or 2 licenses, can go on to have further assessment using Farnsworth Lantern-test or Optec-900. Following this, if the standards are not met, they can consider further assessment with CAD or OACVA. This only applies to licence category 1 & 2. Class 3 must pass Ishihara testing to meet the standards.

  5. Contrast sensitivity: Assessing the candidate’s ability to see adequately in low-contrast environments.


The aviation eye examination

An eye exam for a Class 1 or Class 3 licence typically takes approximately one hour. It involves a full assessment of vision, including binocular vision, peripheral vision and an ocular health assessment.

Remember to bring your glasses and contact lenses (if appropriate) to the exam. CASA requires that you have a minimum of two pairs of glasses and that your vision is tested with both pairs of glasses, so bring all glasses with your current prescription to the exam.
