Progressive lenses provide a transition from near, intermediate, and far vision prescription. As compared to bifocal lenses, progressives provide a wider zone of clear vision to make activities like computer use and reading easier for the wearer.
Progressive lenses have three prescriptions in one pair of glasses. That allows you to do close-up work (like reading a book), middle-distance work (like checking out a website on a computer), or distance viewing (like driving) without needing to change your glasses. They're sometimes called multifocal lenses.
Some people find that a progressive lens is better than a single-vision lens because it allows them to see clearly at different distances without the need to carry a second pair of eyeglasses. A progressive lens does the job of a single-vision lens and reading glasses, so that you only have one pair of glasses on hand.
Progressive lenses are an all-inclusive type of eyewear that helps you see up close, far away, and everywhere in between. That means that progressive lenses are good for driving, so if you plan to take a road trip or drive to work, you can feel confident in your choice of vision correction.
People have reported that they feel unstable, can't read or even can't see out of them at all. The vast majority of adaptation issues with progressives lenses aren't from the lenses at all, rather they are caused by the fitting of the lenses to the patient.
Progressive lenses tend to be blurry on the sides because each lens promotes three fields of vision: An upper lens segment designed to help the wearer see objects in the distance. A lower lens segment designed to help the wearer see objects within very close proximity.
Answer: Some people may experience a distortion of their peripheral vision after receiving a new glasses prescription. This is a fairly common occurrence that can be a result of the adjustment period as your eyes get used to the new prescription.
If you've noticed that you have to lower your head or glasses to read at a distance, this could be a sign that your progressive lenses have been fitted high on your face. Either you or your eye doctor may be able to correct this by adjusting your frames to sit lower on your face or by widening the nose pads.
Progressive lenses allow you to see at all distances with one pair of glasses. They start with your distance prescription (if you have one) at the top of the lens and increase as you move toward the bottom of the lens. You simply move your head position to allow you to focus through different areas of the lens.
The most common complaint when adjusting to progressive lenses is blurry vision, headaches, nausea and balance issues. It can take some time to train your eyes and brain to see clearly at a distance and close-up. Most people will adjust to their new lenses in only a few days but for some, it could take up to two weeks.

Once you are adapted to your lenses, wearing them part time is no problem. One exception to this is: you should not drive in your progressives until you feel comfortable in them. Usually after a day or two, this is no problem.
Bifocals do sport a traditional design with lines between the fields of vision, while progressive lenses offer seamless lens transitions and have no visible lines – a selling point to many.
Some wearers of night driving glasses report that they're better able to see at night while wearing them. However, visual tests indicate that night driving glasses do not improve night vision, and do not help drivers see pedestrians any faster than they would without them.
What that means is the image is a different size in each eye. On top of that, as you move your eyes around, this difference in magnification gets even more dramatic and causes the distortion, double vision and general discomfort you may experience.
Progressive wearers should avoid aviators and cat-eyes because both can cut off the bottom portion of the prescription, resulting in a loss of reading vision. Instead, they should look for shorter frames with rounded edges such as horn-rimmed, retro wingtip, circular, and oval ones.
When vision needs correction for near- and farsightedness as well as astigmatism, progressive lenses are an optimal choice. Progressive lenses are especially beneficial for those experiencing age-related farsightedness (presbyopia) who also have astigmatism.
Besides progressives and bifocals, there are also trifocal lenses or bifocal contacts. Like progressives, trifocals offer three fields of vision, but have two visible segment lines that mean a double image jump. New designs in bifocal contact lenses are also an alternative.
