ROAD SAFETY AND HEALTH :: LEARN ABOUT YOUR HEALTH
Why is good eyesight so important?
HOW ARE THE EYES USED WHEN DRIVING?
This is the ability to focus and see clearly with both eyes. With good visual accuracy you will see detail very easily. For professional drivers this is very important, because good visual acuity is what helps you to identify road signs, cyclists, pedestrians and animals.
All Round Vision
This is the ability to see over a wider area without moving your eyes of your head, as if you are “looking out of the corner of your eyes”.
This is the ability to judge space and distance between objects, or between an object and a vehicle. Depth perception relies on good binocular vision, which is essential for judging whether a car can be passed safely in the face of oncoming traffic or when moving from one lane to another.
The ability to see during low light beyond your headlights, to see in the glare from oncoming headlights and to recover quickly from the effects of glare. Night vision deteriorates with age and older drivers with reduced vision will need to exercise greater care when driving at dusk and at night.
SIGNS OF DETERIORATING EYESIGHT:
HOW DO VITAMINS HELP MAINTAIN GOOD VISION?
Vitamin A – Maintain good night vision, and is found in liver, carrots, cabbage, pumpkin, tomatoes and broccoli. Heat, light, alcohol, coffee and smoking destroys Vitamin A.
Vitamin B2 – A shortage of Vitamin B2 causes burning eyes, sensitivity to bright light and cataracts. Mushrooms, asparagus, bean sprouts, milk and fish are good sources of Vitamin B2.
Selenium – Too little selenium in your diet could cause cataracts. Make sure you include tuna, herring, cottage cheese and chicken to keep selenium levels up.
