Tinted lenses are not recommended for night driving or when visibility is poor. Although the tint can reduce the intensity of headlights, it will also reduce the brightness of surroundings. It is more difficult to see in the dark than in the light, so making everything darker will make things even more difficult to see.
Sunshine can dazzle drivers, particularly when the sun is low. If you wear glasses you should find it helpful to wear prescription sunglasses such as Xperio polarising lenses. We also recommend our range of Mint Magnetic frames which include a polarising Clip Lens which attaches magnetically to the front of the frame. Polarising lenses improve contrast and definition in bright light.
If your glasses have photochromic lenses, which go darker in the sunshine, you will probably find that they do not go as dark in the car. This is because the darkening is triggered by the ultra violet radiation in sunlight, and much of this is absorbed by by the windscreen. We recommend Transition XtraActive lenses which are designed to have greater activation behind the windscreen when compared to standard Photochromic Lenses.
When Choosing frames for driving, try to avoid those that have thick, heavy sides. This is because they tend to block your vision to the side (rather like a horse wearing blinkers).
Frames with thinner sides are better for driving as you will be able to see around them to the side more easily.
Have regular eye examinations and check your vision between these
Your vision can deteriorate slowly without you noticing it, particularly if this happens in one eye only as you will still see clearly with the other eye.
We recommend that you make yourself aware of what is normal for you in each eye separately (with glasses if required), and visit us if you notice any changes.
Even if you do not notice any changes in your vision, we recommend regular eye examinations to make sure your eyes are healthy and you are seeing as clearly and comfortably as possible. For most people we recommend an eye examination at least every 2 years.
