According to the Optometrists Association of Victoria, around 47 per cent of the population suffer from at least minimal visual disorders.
How will you know if your eyesight is good enough for driving?
Before you apply for a driving licence, you need to declare any illness, disease or disability to the optometrist. This is important if you are facing difficulties to concentrate or focus on driving. It indicates that you have a refractive error or short or long-sightedness that needs to be rectified. Optometrists are able to provide you with a proper certificate stating that your eyesight is quite healthy for driving.
The process may include the need of corrective lenses, all the more if you have a history of eye surgery. Driving eye test in Victoria is specifically important for aged drivers to determine the medical and eyesight condition for proper driving.
Visual acuity measurement
Visual acuity is measured with the help of Snellen chart, and individuals are asked to read a series of letters starting from larger to fine prints. Even some testing includes an application of light directing right on the eyes and then reading the Snellen chart. This ensures that even if you face any bright light from the opposite side you can drive safely.
The test for heavy vehicles is more stringent, and you need to clear more intricate methods.
Visual field testing
The angle of your views from both eyes determine the quality of your driving, which means testing of your peripheral vision. To clear this test, you must have a horizontal extent of vision of at least 110 degrees. If any defect is discovered, you are not eligible to obtain a licence.
What if you have a monocular vision?
An eyesight certificate issued by a reputed optometrist is very important for drivers with a single eye vision. This is because the visual fields get reduced and they have no stereoscopic vision. Even if they clear for a license, it includes some specific rules and conditions for driving. Some monocular vision drivers are recommended to stop driving at all. Whether the license will be issued or not is then determined by the licensing authority.
Eye test for driving is very important for you and your family’s safety. Contact an optometrist immediately if haven’t yet.
