Contact lenses have an optical advantage over glasses. The change of image size is minimised compared to glasses. Ring scotomas (area of visual field missed) caused by spectacle frame and lenses are eliminated as are peripheral aberrations induced by a spectacle lens.
However, an ATCO will need to ensure that the lenses can be worn comfortably for the duration of their duty. It is important that the wearing times do not impact on the visual acuity, comfort or eye health. All contact lens wearers are expected to attend for regular check-ups as advised by their contact lens practitioners.
All contact lens materials (Gas permeable, soft, soft disposable, hard) are acceptable provided they are well tolerated. Optimum correction must be achieved. The correction of astigmatism should always be considered for soft contact lens wearers (toric lenses).
