Clarity of vision is very important for driving.
Any loss of vision will reduce your ability to drive safely.
With reduced vision you may take longer to perceive and react to a hazard ahead. You may also fail to see another vehicle or pedestrian, especially in demanding conditions such as rain, highway speeds, or night driving.
If you have any vision or eye disorders, the department recommends that you speak to your doctor as you are required to provide a Medical Certificate for Motor Vehicle Driver (form F3712). You will also be required to provide a medical certificate from your doctor if you only have vision in one eye (monocular vision).
Note: Your doctor may refer you to an optometrist or ophthalmologist for further assessment before they issue the required medical certificate.
If you need to wear glasses or contact lenses when driving, your licence will show an 'S' licence code indicating that you must wear corrective lenses when driving.
