Vision Testing For Drivers

When you apply for a driver license, or if you want to renew or extend your old license, the Department of Motor Vehicles (DMV) will ask you to appear for a vision test for driving which is called as DMV Vision Test.

Reasons for the test: It is the responsibility of the DMV to ensure highway safety. For this, they require all drivers to be competent, and it is here that vision plays an important. Proper vision plays an important part in driving a motor vehicle well and safely on the highway. Proper vision ensures that you can read all road signs, see oncoming vehicles, and gauge other highway requirements, which need vision. That is why a vision test for diving is essential and must meet certain standards, not only for your own safety, but also for the safety of other drivers on the highway.

The vision test for driving is quite intensive and measures certain specific areas. It checks the severity of the vision condition, if eyesight is not normal. It checks central and side vision, both of which are necessary in road driving. It checks if your vision problem affects only one eye or both. It also ascertains if the vision problem can be corrected by contact lenses or glasses or laser surgery. The vision test for driving also checks the nature of your vision condition and whether it can improve or get worse

The test standards: All drivers must meet with the minimum standards of vision. This means that you should have at least 20/40 in both eyes. the driver could also have 20/40 vision in one eye, and at least 20/70 in the other one.

The vision test for driving uses a wall chart with five lined of letters, in various sizes. You will be asked to read the chart by standing 20 feet away from it. If you are unable to read all the letters on the wall chart, you will next be tested on a vision tester. This is a machine called the Optec 1000, and you have to look into the eyepiece with both your eyes open, and find some specific objects projected in the machine. This test helps to measure the visual acuity of the eyes together and individually.

If you are unable to meet the standard requirement of a 20/40 vision, you will be given an examination form, and asked to consult a ‘vision specialist’ who is a licensed and qualified optometrist or ophthalmologist. If your vision could be corrected, you will have to come back within 6 months with the corrective procedures and take the vision test again.
