                                                     (b) if the lenses are of the hard or gas‑permeable variety, demonstrates the ability, immediately after removing the lenses, to read at least 6/9 with spectacles binocularly

                                                     Note: For how to demonstrate this, see subregulation 67.150(6).

67.155  Who meets medical standard 2
 (1) Subject to subregulations (2) to (7), a person who satisfies the criteria in table 67.155 meets medical standard 2.
 (2) A person may use contact lenses to meet the criterion in item 2.35 of table 67.155 if the lenses are monofocal and not tinted, and are well tolerated.
 (3) A person whose visual acuity in either eye is worse than 6/60 must provide a full ophthalmic report to CASA.
 (4) A person who has undergone surgery affecting the refractive status of either eye is taken not to meet the criterion in item 2.35 of table 67.155 until he or she is free of safety‑relevant sequelae of the surgery.
 (5) A person who requires both near correction and distant correction to meet the criteria in items 2.35 and 2.36 of table 67.155 must demonstrate that 1 pair of spectacles is sufficient to meet both requirements for correction.
 (6) A person must demonstrate that he or she meets the criterion in item 2.39 of table 67.155 by:
 (a) in daylight, or artificial light of similar luminosity, readily identifying a series of pseudo‑isochromatic plates of the Ishihara 24‑plate type, making no more than 2 errors; or
 (b) for somebody who makes more than 2 errors in a test mentioned in paragraph (a), readily identifying aviation coloured lights displayed by means of a Farnsworth colour‑perception lantern, making:
 (i) no errors on 1 run of 9 pairs of lights; or
 (ii) no more than 2 errors on a sequence of 2 runs of 9 pairs of lights; or
 (c) for somebody who does not satisfy paragraph (a) or (b), correctly identifying all relevant coloured lights in a test, determined by CASA, that simulates an operational situation.
 (7) If a change is made to a criterion in an item of table 67.155, a person who held a class 2 medical certificate and satisfied the criterion immediately before the change, but fails to satisfy the criterion as changed, is taken to satisfy the criterion for 2 years after the day when the change is made.
