According to the AsnaV, more than 90% of the decisions and gestures involved in driving a car rely upon the driver’s eyesight. But your eyes are not accustomed to working in low or very strong light, nor at high speeds. Here are a few remarks about eyesight….and the law.
How to see better while driving at night or day
Good visual acuity helps to guarantee safe driving, so it is necessary to have regular check-ups with an ophthalmologist;
- Driving is prohibited for people who don’t have binocular acuity of at least 20/40 (if one eye has a visual acuity of less than 20/200 the other must have at least 20/34);
- Not wearing corrective eyewear if your driver’s license says it is mandatory is an infraction of the law;
- Opt for glasses with a protection index from 1 to 3; category 4 is forbidden for driving;
Polarized lenses, corrective or not, diminish glare and improve the driver’s comfort;
- Photochromic lenses, corrective or not, automatically adapt to the intensity of light so the wearer does not have to carry more than one pair of eyeglasses for different light conditions;
- Glasses for night driving improve contrast and reduce glare;
- Glasses worn while driving must be clean and without scratches or nicks; these irregularities accelerate eye fatigue.
A closer look at eye protection for ATV and motocross
Dust and other projections mean that fans of motocross and ATV’s must wear protective masks. Here is some advice on deciding which ones to choose and what to do if you wear glasses.
- The best choice is a mask with a ventilated double lens; at the very least, choose a simple lens with anti-fog treatment;
- Choose a polycarbonate lens;
- Equip your mask with a tear-off lens cover to keep your lens clean while riding;
- If you wear glasses, look into prescription goggles or optical clip-ons.
Cyclists and mountain bikers, protect your vision!
Choose wraparound glasses for cycling. For mountain biking in rugged terrain, choose curved frames with anti-slip arms and bridge; for downhill, choose a mask;
- Avoid frames with a large rim at eyebrow level
- Opt for lenses, corrective or not, with a protection index from 0 to 4 depending on the intensity of the sun; photochromic or interchangeable lenses are another option;
- Get hydrophobic, polycarbonate lenses with anti-fog treatment;
- Try to find ventilated frames if possible.
On a motorcycle or scooter, seeing clearly is critical!
If necessary, wear protective eyewear but avoid contact lenses; they risk coming out or drying your eyes;
- Eyeglass frames should be flexible and the lenses (or a helmet’s visor) must be anti-glare, anti-fog, scratch-resistant and hydrophobic. Use lenses or visors made with organic material so as to avoid injury in the event of a fall.
- Even in sunny weather, use an untinted visor and sunglasses with a protection index from 1 to 3. This is more convenient than using a tinted visor, which is forbidden at night. Photochromic lenses are recommended because they adapt automatically to different light;
- Using a visor and polarized lenses at the same time will hinder your vision.
