You have to be able to see without glare and reflections during the day, but also clearly and with contrast at night. Your eye care professional can assist you in selecting anti-glare sunglasses or distance glasses for driving. While most presbyopes these days choose line-free progressive lenses, conventional bifocals and trifocals have some advantages over progressives. In particular, bifocal and trifocal lenses usually provide wider lens areas for reading and computer work than progressive lenses. As we grow older it becomes more difficult to focus on objects close by. This is a perfectly normal process called presbyopia. The purpose of the lens in our eyes is to change shape as we focus on objects at different distances, with age the lens becomes less flexible so even if you have never worn prescription glasses before you will need help with reading. If you have previously worn glasses you will now need a different prescription for reading. Some people who are short-sighted may find that they are able to read if they take their glasses off. What is the difference between bifocals and varifocals - will the lenses have a line? The Double-D multifocal lens is great for car mechanics, who need to see their tools and other near objects, but also need to work on vehicles on a lift above them.

To test the best night driving classes, we wore each pair while driving through a city at night. We compared the effects of driving without the glasses and between each set of glasses. In addition to driving with each pair of glasses, our tester also gazed directly into the bright high beams on our test vehicle from outside the car. Why You Can Trust UsThe E-D trifocal is an excellent choice for someone who needs a very wide field of view for objects at arm’s length and also must see clearly both close-up and in the distance. A television production person, for example, who must keep an eye on several TV monitors spread out in front and to the sides while being able to read notes from a clipboard and recognize someone across the room, is a good candidate for this lens. Your driving lenses must meet a combination of requirements to ensure safe and comfortable vision on the road. Bifocal glasses are a common style of corrective lenses that help combat vision changes that come with age. As you get older, it becomes more difficult for your eyes to focus on close objects. Bifocals are great corrective tools for this since they include two prescription vision strengths on each lens. But, how easy is it to drive with bifocals?

Bifocals and trifocals have visible lines, but the line in a round-seg bifocal tends to be less noticeable than the lines in flat-top and executive styles. Computers are an excellent example of something that is in a person’s intermediate zone. Motorists who need to see in the distance to drive, to see the gauges on the dashboard, and to read a map also would benefit from a trifocal.Measurements conducted by the FKFS 2 Institute on behalf of ZEISS shows that drivers look at the road ahead and at oncoming traffic for an average of 97% of their overall driving time, probably a higher average than you would’ve guessed! On top of that your eyes also have other tasks to perform. They need to rapidly shift focus between the side mirrors, the rear-view mirror and the dashboard. This is an easy task for young drivers, but when you reach the age of 35-40 onwards, your eyes are no longer able to adapt (or "accommodate" as the experts say) to different distances as fast as they could when you were younger. You may need special progressive lenses, also known as varifocals for driving to overcome this obstacle.
