Driving & Defective Eyesight

As expected, Malaysian law is as informative as a nut.

So here's UK law, mind-mapped because I needed an excuse to try out the mind-mapping software, followed by the criteria used to assessed eyesight.



Eyesight requirements
The following requirements apply to holders of licences for cars and motorcycles. It is a criminal offence to drive a vehicle on the road if you cannot meet these eyesight requirements

Visual acuity
You must be able to read in good daylight, with the aid of glasses or contact lenses if worn, an old style standard vehicle number plate at a distance of 20.5 metres (67 feet) or a new style number plate at a distance of 20 metres (65 feet) where narrower characters are displayed. New style number plates were introduced on 1 September 2001 and start with two letters; for example AB51 ABC.
This is the standard eyesight requirement for someone taking a driving test.

Field of vision
You must have a good all-round field of vision for safe driving to ensure that you are aware of approaching vehicles and other hazards. You must report to the DVLA any significant loss of field of vision when you have both eyes open. This is likely to apply to people with eye conditions where there are defects in the field of vision, including severe glaucoma or retinitis pigmentosa.

Monocular vision
You must notify the DVLA if you have lost sight in one eye. You may drive provided you have good sight in the other eye and can meet the eyesight requirement; the field of vision in the other eye is normal; and when advised by a doctor or eye specialist that you have had enough time to adapt to the loss of sight in one eye.

Visual field defects
Included here are conditions such as severe glaucoma or retinopathy in both eyes, retinitis pigmentosa and others. You must be able to meet the recommended national guidelines for visual field before you can drive.

Cataract
If your sight is affected by cataract or post-cataract surgery, you must be able to meet the standard eyesight requirement above. The effect of glare on your sight may mean you are not able to meet the requirement.

Night blindness
You must notify the DVLA if you are unable to meet the above standards for visual acuity and field of vision, in all conditions.

Diplopia (double vision)
You must stop driving when this is first diagnosed. You may be allowed to drive if it is confirmed to the DVLA that your diplopia is controlled by glasses, or by an eyepatch you have adapted to wearing and which you undertake to wear when driving.

Colour blindness
It is not necessary to notify the DVLA of colour blindness.

Blepharospasm (involuntary blinking or closure of eyelids)
You may continue to drive provided satisfactory medical reports are submitted. You must however inform the DVLA of any change in the condition.

Appealing against a refused driving licence
If you are refused a driving licence or your licence is revoked because of your sight loss, you do have a right of appeal to a Magistrates Court (or Sheriff Court in Scotland). It is important to remember, however, that the Courts cannot overturn what is set down in law. You should seek expert advice at this stage and your local Citizens Advice Bureau or Law Centre can help.
